In fact, machining uneven outer cylindrical surface workpiece or irregular outer cylindrical surface workpiece on CNC turning machine center or CNC lathe machine requires a fundamental understanding of the relationships between workpiece surface integrity, tool life, type of workpiece material, size of workpiece, type of tool tip and machining parameters setting such as depth of cut, spindle speed and cutting tool feed rate and how severe the workpiece outer surface condition. Of course, the tool tip material also need to be considered but I'm not going to emphasize it here because I'm using the standard tool tip, High Speed Steel (HSS) tool tip with nose radius range from 0.4 mm to 0.8 mm to perform the tuning and facing operations. In some cases, I will use the same tool tip for turning and facing operations.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi-t68LQlShLvdLOcY4dAbuxAAs59V5dgAXdwxj58cHZpypP9wyY4RPRHCbFkvPtlqoRaVnfJzp91UF4YfqARw2g5JsPHi88YjjsjF_ebWJnzxXsmQG0zjqn72bHs6hyphenhyphenLCPdMMs3dT1UT8/s1600-h/uneven-cylindrical-surface-2.jpg" target="_blank"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi-t68LQlShLvdLOcY4dAbuxAAs59V5dgAXdwxj58cHZpypP9wyY4RPRHCbFkvPtlqoRaVnfJzp91UF4YfqARw2g5JsPHi88YjjsjF_ebWJnzxXsmQG0zjqn72bHs6hyphenhyphenLCPdMMs3dT1UT8/s1600/uneven-cylindrical-surface-2.jpg" border="0" alt="how to machine and cut uneven outer cylindrical surface with cnc turning machine center" id="BLOGGER_PHOTO_ID_5420303371664652130" width="400px"></a><br /><br />If the machining operation involve time consuming especially when performing mass production then you need to have more powerful tool tip such as carbide tool tip. In CNC turning machine center, single point cutting tool or tool tip also known as an insert because we need to insert the tool tip onto the forged tool holder and attach the tool holder on the turret system or Auto Tool Changer (ATC) before we can use it in the machining operation.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIgltl2NoBlCN_We6MIAYH1B2LqG8YKRwDEivRKFSSKcY3mOdtTsyB0ofcZCHXdgcftHjd-aQna8RuWuoWpKOfOhxvWLYCecCDFMZiwS_Ynb3fPRAt07KZi5d8oA6DAZPM6gm_9QWADA0/s1600-h/uneven-cylindrical-surface-3.jpg" target="_blank"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIgltl2NoBlCN_We6MIAYH1B2LqG8YKRwDEivRKFSSKcY3mOdtTsyB0ofcZCHXdgcftHjd-aQna8RuWuoWpKOfOhxvWLYCecCDFMZiwS_Ynb3fPRAt07KZi5d8oA6DAZPM6gm_9QWADA0/s1600/uneven-cylindrical-surface-3.jpg" border="0" alt="cutting irregular outer cylindrical surface" width="400px" id="BLOGGER_PHOTO_ID_5420303379802481714"></a><br /><br />Machining the uneven outer cylindrical surface workpiece on CNC lathe machine, a rough cut need to perform. When performing rough cut on the uneven outer cylindrical surface or irregular outer cylindrical surface workpiece, it is very crucial to have a correct machining parameters setting. Incorrect machining parameters setting especially the spindle speed, feed rate and depth of cut will led to tool tip blunt very fast, crack or breakdown.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3Vpzd3awJR7ZuA2vhiR19p-JYvXYVKADnCeDOatt6Ae4MfrN5pWLyivx9KFDrSE_MxGh5nq008ndV6Hs6YsYsC3P2Y-6pG863v9F29yF6VeMx7GqCu-ZmlqT289uar_fBuXxP3ZgYyuo/s1600-h/uneven-cylindrical-surface-5.jpg" target="_blank"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj3Vpzd3awJR7ZuA2vhiR19p-JYvXYVKADnCeDOatt6Ae4MfrN5pWLyivx9KFDrSE_MxGh5nq008ndV6Hs6YsYsC3P2Y-6pG863v9F29yF6VeMx7GqCu-ZmlqT289uar_fBuXxP3ZgYyuo/s1600/uneven-cylindrical-surface-5.jpg" border="0" width="400px" alt="machining cylindrical workpiece with cnc lathe" id="BLOGGER_PHOTO_ID_5420303388798824370"></a><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhRryLzH-G6s8xQwRxvXOoPAHFkMc2dxlA0szYH9pBNMWQc9A0tCoSU1gKygrU-ptJO_dMAeIZorSS4tmh4Ke6eCinD2l_-4OTvr-Y8QeqDk2X_tQedXA2hzVxboNWSPrQVFDXLoBIcs5U/s1600-h/uneven-cylindrical-surface-4.jpg" target="_blank"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhRryLzH-G6s8xQwRxvXOoPAHFkMc2dxlA0szYH9pBNMWQc9A0tCoSU1gKygrU-ptJO_dMAeIZorSS4tmh4Ke6eCinD2l_-4OTvr-Y8QeqDk2X_tQedXA2hzVxboNWSPrQVFDXLoBIcs5U/s1600/uneven-cylindrical-surface-4.jpg" border="0" alt="machining uneven outer cylindrical surface" id="BLOGGER_PHOTO_ID_5420303381379269186" width="400px"></a><br /><br />Here are my machining parameters setting when performing a turning rough cut on irregular outer cylindrical surface or uneven outer cylindrical surface workpiece.

For high surface roughness, I myself use roughing cut, boring tool feed rate range from 2 to 4 feed per minute, spindle speed equal to 180 RPM and depth of cut equal to 2.5 mm. For finishing, the boring tool feed rate equal to 5 or 6 feed per minute, spindle speed is 400 RPM and depth of cut is 0.5 mm. The workpiece material is mild steel SS41<br /><br />Summary for boring bar cutting operation:<br /><br /><b>Boring Bar Roughing Cut</b><br /><br />Feed Rate = 2 ~ 4 F/M (Feed Per Minute)<br />Spindle Speed = 180 RPM ( Rotation Per Minute)<br />Depth of Cut = 2.5 mm (millimeter)<br /><br /><b>Boring Bar Finishing Cut</b><br /><br />Feed Rate = 5 ~ 6 F/M<br />Spindle Speed = 400 RPM<br />Depth of Cut = 0.5 mm<br /><br /><br /><img alt="symmetrical workpiece" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkwUPLGGiMeXdEC7SzHVQLbwVtTtYT3XFojvwsugO_hyWuREvxWMhNhYB1l7ioBWlmyeQJzmjqr8uuURTPwtaUv4QOXofZDDS1U1km8ZKyrE300CqFx_RSqguRwnFPJnHBCzeiixeVbFI/s1600/symmetrical-workpiece.jpg" width="400px" /><br />Completed machining part.

It is essential that the CNC machine moving parts should be correctly and adequately lubricated. Failure to practice a proper CNC machine lubrication program at a correct intervals with a proper amount and viscosity of lubricant oil especially on the moving parts will drastically increase the machine maintenance and repairing cost, increase the unscheduled downtime, increase the production cost and reduce the CNC machine lifetime performance. The CNC machine lubricating program is the first defense against premature wear or damage to the machine.<br /><br />The CNC machine lubrication program is the responsible of preventive maintenance staffs. They have to design a solid preventive maintenance program especially the machine lubricating program on the moving parts such as spindle, linear guides and ballscrews. Base on my experienced, the machinists or the machine operators are part of the first defense system against chronic CNC machine failure because they have the capabilities to monitor the lubricant oil level especially during ordinary machine operation then, they should be part of the CNC machine preventive maintenance team.<br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjsDml9FOipbT-cfBaMOC6cJvos8BmizATlnoc6YvZs6JwEwHp0XuFN5LJqglr1eiy9KahBnA8M83L5WBZ2S-axEuK20MQwVUSYRlTCJmhBdiDa5C_1KAON2dhnplxF1mOq0wjVvCcLGas/s320/manual-lubrication-pump.jpg" border="0" alt="centralized manual lubrication pump" /><br /><br /><b>Centralized manual lubrication pump</b><br /><br />Nowadays, most of the CNC machines in the market are equipped with the centralized lubrication system to deliver the lubricant oil to the lubrication points on the CNC machine whether using hand operated oil pump (manual lubrication pump) or motorized oil pump (automatic lubrication pump). Basically, most of the centralized manual lubrication pumps are used on the small CNC machines and most of the centralized automatic lubrication pump are used by bigger CNC machine or multiple axises CNC machine. Centralized <a href="http://cnc-machine-center.blogspot.com/2009/05/automatic-lubrication-pump.html">automatic lubrication pump</a> uses programmable timer to deliver precise amount of lubricant oil to the lubrication points. The centralized lubricating system drastically reduce the preventive maintenance cost. However, centralized manual lubrication pump still need comprehensive machine lubricating schedule. An efficient CNC machine lubricating program is the essential tool to keep the CNC machine running smoothly.<br /><br /><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgO5wU0MEAElfhO5KFCvJ1tD8Ws5dz3wgeUzCOEQKmYCZ4PhUxaSPVVZrC3gCLwuX9UGpGH6iAzpZxHyGUSxBM8hh_khk-R5b7Hln3Nb1tAShatBHsCiBcu0qlQ4CpyRaFYO2zBAjs-o3c/s320/automatic-lubrication-pump.jpg" border="0" alt="centralized automatic lubrication pump" /><br /><br /><b>Centralized automatic lubrication pump</b>Anonymoushttp://www.blogger.com/profile/04031240857354225771noreply@blogger.com0tag:blogger.com,1999:blog-8705889039742763167.post-74415091523197699822008-12-19T03:23:00.000-08:002008-12-19T04:17:11.992-08:00415VAC 3 Phase to 240Vac Single PhaseThis is the CNC machine basic wiring diagram to step down the 415 VAC 3 phase power line to 240VAC single phase.

In fact, most CNC machine spindle motor can use whether 415 VAC 3 phase or <a href="http://cnc-machine-center.blogspot.com/2008/12/220vac-3-phase-to-110vac-single-phase.html">220 VAC 3 phase</a>. The use of 240 VAC single phase is very seldom in CNC machine however some CNC machine retrofitter will use this power line to retrofit the CNC machine especially to power up the lamp and lubrication system but mostly depends on the industrial electrical components standard input power of each country or state.<br /><br />When building a CNC machine, Earth Leakage Circuit Breaker (ELCB) and MCB must be used to ensure all the CNC electrical and electronic components are well protected. For extra protection, fuses are also will be used. I myself use ELCB range from 40 Amp to 80 Amp, MCB range from 20 Amp to 32 Amp and fuses range from 10 Amp to 20 Amp.Anonymoushttp://www.blogger.com/profile/04031240857354225771noreply@blogger.com1tag:blogger.com,1999:blog-8705889039742763167.post-56002709873907373282008-12-16T09:13:00.000-08:002008-12-16T09:47:58.016-08:00220VAC 3 Phase to 110VAC Single PhaseNowadays, most CNC machines are using 220VAC 3 phase power supply to power up the spindle motor and other electrical components such as coolant motor and inverter.

Basically this CNC machine controlled by the CNC machine controller which consists of a CNC servo drive to control all the electrical parts such as axes servo motors, coolant motor, hydraulic motor, spindle motor, lubrication motor, inverter, working light, DC contactors and DC reversing contactor. The CNC controller panel is located in front of the CNC machine and not shown on this CNC circuit diagram.<br /><br />The type of CNC servo drive shown on the diagram is 2 in 1 CNC servo drive which consists of servo drive and programming logic control section (PLC). The PLC section has some input and output (I/O). The electrical parts which will generate the signal such as limit switches, sensors, button, emergency switch and etc will be connected to the PLC input to be processed and the PLC will turn on some of the related PLC output. Those electrical parts that will receive the instruction from PLC such as motor, light, solenoid valve, contactors and etc will be connected to the PLC output. The output itself can be act as an input or signal to the PLC but the input never be act as an output. <br /><br />Each axis servo motor and its encoder are connected directly to the CNC servo drive to ensure the CNC servo drive gain fully control on each servo motor in order to synchronize the movement of the mechanical parts especially the movement of machine tool on the raw material when machining the part. The coolant motor, hydraulic motor, lubrication motor and working light will be connected to DC contactors and each contactor will be connected to the servo drive PLC output.<br /><br />The rotation of the spindle motor whether clock-wise (CW) or counter-clock-wise (CCW) is controlled by the DC reverse contactor when instructed by the servo drive. The encoder of the spindle motor is connected to inverter and servo drive to ensure to machine tool can do rigid tapping. In fact, you can connect the output spindle CW and the output spindle CCW on the servo drive directly to the inverter CW and CCW respectively to control the spindle rotation direction without using DC reversing contactor. I will show you the circuit diagram on my next blog post. I also will try to get more vivid CNC circuit diagram image for the next blog post. <br /><br />The limit switches are used to determine the homing position and the maximum travel distance of each axis.

The diameter of EDM wire is between 0.05mm (0.002") to 0.33mm (0.13") and the wire tensile strength is more or less than 900N/mm² (130,000psi) depends on the type of wire.<br /><br /><img src="http://www.landmarktec.com/01-edm_cutting_wire.jpg" alt="edm brass wire" ><br />EDM brass wire<br /><br />Photo by <a href="http://www.landmarktec.com/" target="_blank">Landmark Technology Co., Ltd</a><br /><br />The wire EDM machine is generally used when the cut goes all the way through the workpiece and the electrode will be electrically energized to slice through the metal workpiece. The wire is pulled through the workpiece being cut and cooled by a dielectric fluid or deionized water which acts as a coolant. During machining process, the wire itself will be traveling from wire spool into the wire bin reel and the traveling distance will be controlled by the machine program.<br /><br /><img src="http://www.xactedm.com/images/wire.jpg" alt="edm wire" ><br />EDM Wire<br /><br />Photo by <a href="http://www.xactedm.com/" target="_blank">XACT Wire EDM Corp</a><br /><br />The electrode and the workpiece are either fully submerged, or flushed with a deionized water. To start machining it is first necessary to drill a hole in the workpiece or start from the edge. When the electrically energized wire approaching the workpiece the electrical discharge or spark will be created. The spark will jump to the workpiece which will erode some small amount of workpiece and flush away by the deionized water to form the spark gap between the wire and the workpiece. The spark gap size can be controlled as small as 0.0127mm (0.0005").<br /><br /><img src="http://tds.ic.polyu.edu.hk/dfm_guide/edm_wire_cut_product.jpg" alt="EDM wire cut possible machining shapes" width="" height=""><br />EDM wire cut possible machining shapes<br /><br />Photo by <a href="http://tds.ic.polyu.edu.hk/dfm_guide/edm_wire_cut.htm" target="_blank">Hong Kong Polytechnic University</a><br /><br />The Wire EDM machine uses rapid and repetitive electrical discharges to create more and more spark gap. The spark gap will allow the wire to advance further until the workpiece is cut through. The EDM is a non-contact cutting process, the wire itself does not touch the workpiece and the actual cut is done by the spark. This eliminates machining forces that can cause distortion. The quality of the product depends on the spark gap size, the smaller the spark gap size, the smoother the surface, but the machining time is much more longer.<br /><br />EDM wire cut produces excellent dimensional accuracy with a high quality surface finish, suitable for cutting intricate shapes or irregular shapes and tight radius contours to create complex dies and other tools from extremely hard materials. It is ideal for cutting hardened materials above HRC 38.<br /><br /><img src="http://www.cncmachinery.com.au/mmedia/JS%20W-A430.jpg" alt="cnc edm wire cut machine" width="" height=""><br />CNC EDM Wire Cut Machine<br /><br />Photo by <a href="http://www.cncmachinery.com.au/" target="_blank">CNC Machinery, Inc.</a><br /><br />Most EDM machines are controlled by computer numeric control (CNC). The CNC wire cut machine is an equipment to produce very fine cuts in the metal workpiece. The cut can be as thin as 0.0127mm (0.0005"). The accuracy of the machine could be as precise that it can produce a tolerance of less than 10 micron. This kind of machine is an essential requirement for making precision dies or moulds. Wire EDM requires no special special fixtures and in most cases the machine can run unattended. This makes the EDM wire cut is one of the most cost-effective process, allowing you to reduce inventory and fast delivery dates. This will contribute to improve cash flow and reduce operating expenses.Anonymoushttp://www.blogger.com/profile/04031240857354225771noreply@blogger.com0tag:blogger.com,1999:blog-8705889039742763167.post-22059167157906417442008-10-04T23:54:00.000-07:002009-04-08T09:01:06.310-07:00CNC Lathe / CNC Automatic Lathe LNT36/52/65 S-Series<b><i>LICO Machinery Co., Ltd., the professional manufacturer of Cnc lathe,CNC turning centers, CNC AUTO LATHE,AUTO LATHE,CNC Machine Center</i></b><br /><br />Issued By: Lico Machinery Co.,Ltd<br /><br /><a href="http://www.prlog.org/" style="text-decoration: none;">PRLog (Press Release)</a> – Aug 29, 2008 – The machine CNC LATHE / CNC Automatic Lathe - LICO, a leading manufacturer of automatic lathes in Taiwan,recently announced a newly developed automatic bar machine,LICO CNC Multi-Slide Automatic lathe,model LNT36/52/65 S-SERIES.

These tools are made from sub-micro grain carbide and are available in regular and long lengths. Additionally, they can be ordered uncoated or with a high performance zirconium coating. We have been marketing American made tooling on the internet and have been serving customers for over 2 years. We offer a full line of metal cutting tools such as…end mills, drill bits, threadmills, micro end mills, hand taps, NPT Pipe taps, S&D drill bits, and center drills.<br /><br />End mills are fluted tools designed specifically for periphery and slot cutting applications. They can be used to machine steel, plastic, wood, stainless steel, aluminum and many other materials. They are sought after because of their precise ability to cut to exacting tolerances when utilizing a manual or CNC milling machine. A flute is simply a cutting edge, sometimes with a helix, sometimes straight, your application will determine which style you choose. Helical flutes pull the chips up, and out of the way, the cutter can then cut more freely reducing heat buildup and decreasing machine cycle times.<br /><br />End mills can have a vast number of flutes. Most common in machine shops are 2, 3 and 4 flute tools. Four flute cutters give you four cuts per rotation and are preferred in profile milling applications. Four flutes are not as useful in softer materials because they do not provide enough space between the flutes to evacuate chips sufficiently, whereas the two flute cutters are not as durable in very abrasive materials. Therefore, two flute end mills are superior in softer more flexible materials and four or more flute cutters are generally preferred in very hard or abrasive materials.<br /><br />When using an end mill to cut a slot in a work piece, it’s best to have a hole already in the part. That way the end mill will not have to cut to center. Kodiak cutting tools offers a wide variety of hss, cobalt and carbide drill bits for your slot starting needs. Also, a two flute end mill is the best tool for a slotting cut. When a 2 flute end mill is used, the chips are lifted out of the slot. If the chips don’t get up and out of the cutters way, the end mill will re-cut the chips causing premature failure. Additionally, if a four flute end mill is used, the chips may become lodged in the flutes causing the tool to break. Kodiak Cutting Tools offers a wide variety of 2, 3, 4, 5 and 6 flute end mills.<br /><br /><br /><b>About The Author</b><br /><br />Written By Dave Butry, An associate of <a href="http://www.kodiakcuttingtools.com/" target="blank">www.kodiakcuttingtools.com</a><br /><p><br /><p>Anonymoushttp://www.blogger.com/profile/04031240857354225771noreply@blogger.com1tag:blogger.com,1999:blog-8705889039742763167.post-45608696528711998352008-10-01T09:51:00.000-07:002009-04-08T09:00:18.557-07:00Guide To CNC Machinesby: <b>Charles Mohaney</b><br /><br />CNC machines are used in a variety of industrial settings and in woodworking shops. Most are out of the price range for the individual user, but can be purchased used for about half the price. These machines increase speed and accuracy when doing large jobs or repetitive tasks.<br /><br /><b>How CNC Machines Work</b><br /><br />CNC machines are used in a variety of industry, manufacturing processes and woodworking shops. CNC routers are used for drilling holes. Some machines have the capability of holding several tools. This allows them to perform more than one operation at a time. They save time and improve accuracy.<br /><br />CNC stands for Computer Numerated Control. This technology was first seen in the 1970s. The machines need to be programmed and set up properly before operation. Once the initial set up is completed, they are fairly easy to operate and keep running. <br /><br />In CNC routers, they can be programmed to drill holes in an automatic fashion. This is faster and more accurate over several pieces than in manual drilling. The results are more uniform. This method is very beneficial for larger jobs that require a lot of drilling. Manual drilling can become tiring and when the operator becomes tired, the results can become inconsistent.<br /><br /><b>Types of CNC Machines</b><br /><br />A CNC lathe is a good piece of equipment for cutting wood. These come in models ranging from fifteen to forty horsepower. The amount of power you need depends on the amount of wood you will use with the lathe. The best models operate in several different modes, from completely manual to all CNC. This allows you to tailor the machine’s operation for each project.<br /><br />A Bridgeport mill is the best in milling technology. Mills are used in many industries, both large and small shops. They are efficient and reliable. Bridgeport mills are built to last a lifetime. However, they are very expensive. The price is out of the range that most people can afford.<br /><br />The CNC mill is a specialty piece of equipment. It uses computer programming and robotics for accurate operation. The results are more accurate than any person could ever achieve. For this reason, Bridgeport mills are often used in the airline industry. Once the specs are entered, the CNC decides which tools need to be used and automatically changes the tools as needed.<br /><br />Engraving equipment is made to engrave a variety of materials including glass, stone, metal, wood, composites and many others. The machines mark and engrave with more accuracy than could ever be achieved by hand. Everything from large signs to small lettering can be done, depending on your needs.<br /><br /><b>Buying Used units</b><br /><br />CNC equipment is very expensive and out of the price range of most people. Buying used CNC electronics is an affordable option for some people. You can save nearly 50% or more on some equipment. Be careful when buying used, you want to be sure the equipment is in good condition.<br /><br />A better option is to look for refurbished equipment. These machines have been inspected at the factory. Any broken or damaged components are replaced. In many cases, the machine is painted and new decals are applied. It’s like getting a new machine for a significantly reduced price. Often, you will get a one year warranty with reconditioned equipment. This gives you time to be sure it is working properly and if not, you can get it fixed for free.<br /><br /><br /><b>About The Author</b><br /><br />Charles Mahoney publishes many articles for the website <a href="http://www.inside-woodworking.com/" target="blank">http://www.inside-woodworking.com</a>.

A laser cutter works by focusing a high power laser beam at a specific location on the surface of the workpiece. The energy in the laser beam is absorbed into the surface of the workpiece, and converted into heat. The energy density in the laser beam is extremely high, it is enough to melt or vaporize the surface of the workpiece. The melting surface will be propagated until the workpiece is cut through.<br /><br /><br /><img src="http://www.mundtinc.com/artic_sm.jpg" alt="laser cutter arm" width="350" length="267"><br />Articulated laser cutter arm - 6 axes of motion<br />Photo by <a href="http://www.mundtinc.com/" target="_blank">Mundt Inc</a><br /><br /><br /><img src="http://www.madewellproducts.co.uk/images/bysprint.jpg" alt="cnc laser cutting machine" width="350" length="96"><br />CNC Laser Cutting Machine<br />Photo by <a href="http://www.madewellproducts.co.uk/" target="_blank">Madewell Products Limited</a><br /><br /><br /><img src="http://www.vancemetal.com/Images/LaserCutter.jpg" alt="laser cutter machine" width="350" length="231"><br />Laser Cutter Machine<br />Photo by <a href="http://www.vancemetal.com/" target="_blank">Vance Metal Fabricators, Inc</a><br /><br /><p><br /><p>Anonymoushttp://www.blogger.com/profile/04031240857354225771noreply@blogger.com1tag:blogger.com,1999:blog-8705889039742763167.post-44650330595418669162008-09-26T05:17:00.000-07:002008-09-26T09:40:58.687-07:00CNC Surface Grinding Machine<b>What is CNC surface grinding machine?</b> A CNC surface grinding machine is a machine tool uses for producing micron-precise or ultra-fine finishes on tough workpiece and extremely accurate surface finishing with maximum precision and short cutting times. The surface finishing process will be performed by a rotated abrasive wheel which will remove the access metal from the surface of the workpiece. The abrasive wheels can be made up of various sizes and types of stones, diamonds or inorganic materials.<br /><br />CNC surface grinding machine excels with repetitive, tedious and complicated parts, combines with extremely effective operation of conventional surface grinding machine with the user-friendliness and precision of modern CNC controller, servo drive and measuring systems. Normally the surface grinding machine is used for final machining process to the workpiece which has been machined by other method to get high accuracy in dimension of the workpiece.<br /><br /><img src="http://www.leechind.com/images/jig_grinding2b.jpg" alt="cnc surface grinding machine" width="236" hight="177" ><br />Internal cylindrical grinding <br /><br /><img src="http://www.leechind.com/images/cylindricalGrinding1b.jpg" alt="cnc surface grinding machine" width="236" hight="177" ><br />External cylindrical grinding<br /><br /><img src="http://www.leechind.com/images/cylindricalGrinding3.jpg" alt="cnc surface grinding machine" width="236" hight="177" ><br />Surface grinding final result<br /><br />Photos by <a href="http://www.leechind.com/" target="_blank" >Leech Industries, Inc.</a><br /><br /><br />Surface grinding machine is also used to grind very hard workpiece especially the harden workpiece such as tools, dies and punches.

In fact, certain cases the CNC retrofitting will also take place due to limited capability of the machines especially the manual machines. <br /><br />Downtime will cause a lot of delay in the work flow and it will cause a lot of headaches for a lot of people. Any downtime will cause serious losses and will cause huge loss of revenues as well. Certain machines could have excessive downtime due to a high frequency of maintenance, which may support the decisions to upgrade or retrofit ineffective machine that continues to adversely affect the bottom line and make the production more costly. Sometimes downtime occurred due to improper maintenance, low lubricant levels, high operating temperatures and other factors.<br /><br />CNC retrofitting will be done by converting the manual machine into CNC machine or by replacing existing CNC controller with a new more flexible, and powerful latest generation CNC controller to increase the machines machining capabilities with the most cost effective way to suit your needs. Cost effective retrofit that help you to maximize your productivity. The retrofit provides superior machining capability for much less than the purchase price of a brand new machine.<br /><br />The retrofit possible benefits include:<br /><br />* Improve the machine flexibility up to 5 axis or more<br />* Improve machine accuracy and grad of machining<br />* Easy and flexibly parts programming and machining<br />* Equipped with USB port, RS323 port and Local Area Networking (LAN)<br />* Easy to edit, modify, download and upload programming file<br />* Reduce machine downtime and maintenance cost<br />* Easy machine trouble shooting<br />* Reduce parts damage and scrap<br />* Link the CNC controller with the computer network<br />* Increase the workers confident level and moral<br />* Easy to automate the retrofitted machine with the production line<br /><br />Machines are suitable to retrofit included:<br /><br />1. Milling machines<br /> * Knee mill, bed mill or ram mill type<br /> * Vertical machining center or horizontal machining center<br />2. Lathe machines<br /> * Manual lathe machine<br /> * Horizontal tuning center or vertical tuning center <br />3. Router machines and<br />4. Water jet cutting machines<br />5.

Other popular name for EDM is Electro Discharge Machine. There are two most popular EDM machine, Ram EDM Machine and <a href="http://cnc-machine-center.blogspot.com/2008/10/edm-wire-cut-machine.html">EDM Wire Cut</a>. Ram EDM also known as, Sinker EDM, Die Sinker, Vertical EDM or Plunge EDM. Ram EDM divided into two main categories, Conventional EDM and CNC EDM. EDM is a non conventional machining method to remove unwanted material from electrically conductive workpiece or metal. EDM is a machining method primarily used for hard metals, super-tough alloy, hardened materials or cutting delicate cavities that would be impossible to machine with conventional machining method such as milling, drilling, grinding or with other type of conventional machine tools. Some of the EDM applications are machining aerospace alloys such as titanium, inconel, & hastalloy, removing broken taps, drills, & bolts and machining of carbide dies and tools.<br /><br /><img src="http://www.creatoredm.com/images/PdKind/c-pro1-2-1_01(2).jpg" alt="conventional edm or edm ram type machine" ><br />Conventional EDM or EDM Ram Type<br /><br /><b>How EDM works?</b> Basically, the EDM process is simple the unwanted material removes by use of recurrent sparks applied to a hard metal. An electrical discharge is created between an electrode and the workpiece known as spark to create spark gap or spark erosion between the electrode and workpiece. For Ram EDM, a special brass will be fabricated into a desire shape and use it as an electrode. The brass will be attached to the EDM machine and use it to machine the workpiece under carefully controlled conditions. Read this blog post about <a href="http://cnc-machine-center.blogspot.com/2008/10/edm-wire-cut-machine.html">Wire Cut EDM</a> for more details information.<br /><br /><img src="http://www.creatoredm.com/images/PdKind/pro1-1-1.jpg" alt="edm or electrical discharge machine" ><br />CNC Electrical Discharge Machine / CNC EDM<br /><br />Photos by <a href="http://www.creatoredm.com" target="_blank">Creator Precision co., Ltd</a><br /><br />During EDM process, the current will be switched on and off by moving the electrode up (current off) and down (current on) to control the spark gap. When the current is switched on the spark jumps across the gap and the small amount of unwanted material is removed from the workpiece to allow the electrode to be moved through the workpiece. The electrical spark are very short in duration, approximately 1 microsecond to 1 millisecond each. This process repeats its self over and over again until the electrode is slowly advanced deeper and deeper into the cut. The path of the electrode is typically controlled by a numerical controller (NC) for NC EDM machine or computer numerical controller (CNC) for CNC EDM machine, which allows a desire shapes to be produced.<br /><br />The spark always takes place in the dielectric of deionized fluid which acts as a coolant and when the current is switch off the deionized fluid will flushes away the eroded particles from the workpiece. In fact, the electrode itself does not touch the workpiece being cut because the actual cutting is being done by the electrical discharge or spark created between the electrode and the workpiece.Anonymoushttp://www.blogger.com/profile/04031240857354225771noreply@blogger.com0tag:blogger.com,1999:blog-8705889039742763167.post-54863667764015574912008-09-20T04:45:00.000-07:002008-09-20T09:49:26.412-07:00What is CNC Router Machine?<b>What is CNC Router?</b> The CNC Router is a multipurpose machine. This machine is used to cut wood, plastic or metal, as well as engrave or route out letters on signs. The CNC router is an amazing machine that can do seemingly almost anything, so you can get a lot of usage from this machine. Many small fabrication shops, and even individuals are finding the accuracy and versatility of a CNC Router is very useful. The CNC Router is great for hobbies, engineering prototyping, product development, art, robotic education, production work, furniture, advertisement and other fields.<br /><br /><img src="http://www.axyz.com/Images/table_6000_lrg.jpg" width="350px" height="263px" alt="3 axis cnc router machine"><br />The 6000 series CNC Router Machine<br />Photo by <a href="http://www.axyz.com/" target="_blank">AXYZ Automation Inc</a><br /><br />The 6000 series CNC Router Machine applications including<br />* Plastic fabrication<br />* Education<br />* Aircraft manufacture<br />* Mould making<br />* Wood working<br />* Sign making<br />* Solid surface<br />* Boat building<br />* RV manufacturing<br />* Metal working<br />* Engineered composite panels<br /><br />A CNC Router machine has a similar operation with a plotter and controls by a computer. The CNC Router works on the 3D motion control to make high quality parts for you. Basically, the CNC Router has three axes X, Y and Z. Each axis will be motorized with stepper motor or servo motor that drives the router via a gantry system to form a 3 axis CNC Router machine.<br /><br />Normally, the CNC Router machine will be supplied with a powerful software to do your design or drawing. You draw your work on the computer and convert it to G codes then send your drawing to the CNC controller for final result in 3D. The CNC controller will command the CNC Router machine to make the desired parts for you, quickly and accurately. Most CNC router software will convert your drawing into G codes automatically before send to CNC router machine via router CNC controller. This makes CNC Routers ideal for woodworking, plastic molding, advertisement fields and aerospace industry.Anonymoushttp://www.blogger.com/profile/04031240857354225771noreply@blogger.com0
