The relative moving passage between the wire electrode and workpiece is controlled by a CNC system according to a preprogrammed CNC program to cut the workpiece into desired shapes. Wire Erosion is widely used to cut punches and dies, shaped pockets and many other industrial applications.2009-3-3http://www.china-edm.com/10/89.htmSpark Erosion is a recent machining technique with lot of advantages in particular when machining difficult pieces with intricated shapes. The principle of spark erosion is uncomplicated. A workpiece and tool are placed in a working position in such a way that they do nor touch each other. The workpiece and the tool are conected to a DC source via a cable. The voltage applied between the electrode and the workpiece and the discharge current have a time sequence. The voltage builds up an electrical field throughout the space between the electrodes. They are separated by a gap which which is filled with an insulating fluid.2009-3-3http://www.china-edm.com/19/88.htmHONGKONG TOPWEDM MACHINE TOOL CO.,LIMITED is a high-tech company which specializes in the research and manufacturing of EDM machines including CNC High Speed Wire-cut EDM Machine, CNC Medium Speed Wire-cut EDM Machine, EDM machine and High Speed Small Hole EDM Machine. The "CYAN" and "Topwedm" brand are the registered trademarks.2009-2-28http://www.china-edm.com/10/87.htmSimply speaking, the wire cut EDM machine have repeatedly cutting function, similar with low-speed wire cut EDM machine. In order to maintain the stability of molybdenum wire, to enhance the quality of workpiece surface finishing, therefore, will reduce the wire speed, thus named "Medium speed wire cut EDM".2009-2-26http://www.china-edm.com/10/86.htmCNC high speed wire cut EDM is the special local products in china, which is widely used in mould industry. It is different from CNC slow speed wire cut EDM which is high price in other countries. The price of low speed wire cut EDM is about ten times higher than high speed wire cut EDM. But on the quality, high speed wire cut EDM can also satisfy the wide customers¡¯ demands well.2009-2-26http://www.china-edm.com/10/84.htmSmall hole drilling EDM is used to make a through hole in a workpiece in through which to thread the wire in Wire-cut EDM machining. The small hole drilling head is mounted on wire-cut machine and allows large hardened plates to have finished parts eroded from them as needed and without pre-drilling.2009-2-23http://www.china-edm.com/10/83.htmBoth die-sinker and wire-cut EDM machines use sparks to remove electrically conductive material. But while both types are electrical discharge machines, there are differences in their use and operation. Some of these differences are listed in the following text.2009-2-23http://www.china-edm.com/11/82.htmCNC Middle Speed WEDM(Model: MS-430B/540B/650B), new design, automatic wire tightening, automatic rise and fall.2009-2-21http://www.china-edm.com/11/81.htmCNC Medium Speed WEDM(MS-430C/540C), new design, automatic wire tightening, automatic rise and fall.2009-2-21http://www.china-edm.com/10/80.htmWire Cutting is a type of an electrical discharge machining. It is a thermal mass-reducing manufacturing process by using a continuously moving wire. A thin single-strand metal wire is fed through the workpiece, occasionally occurring submerged in a tank of dielectric fluid or being continuously sprayed by dielectric fluid. This process is used to cut plates that are too thick or too difficuilt to cut with other methods. The wire, which is constantly fed from a spool, is held between upper and lower guides.2009-2-20http://www.china-edm.com/10/79.htmElectrical Discharge Machining (or EDM) is a machining method primarily used for hard metals or those that would be impossible to machine with traditional techniques. One critical limitation, however, is that EDM only works with materials that are electrically conductive. EDM can cut small or odd-shaped angles, intricate contours or cavities in pre-hardened steel without the need for heat treatment to soften and re-harden them as well as exotic metals such as titanium, hastelloy, kovar, and inconel.2009-2-20http://www.china-edm.com/20/78.htmProvide 60 sets of files for storages, three axises can change dimension between meter and Inch. There are 10 functions to mended the processed metal automatically:(1) Program by oneself: You can program the processing conditions depends on your experience; (2) AUTOZ programs automatically: Giving the biggest depth at the first of electric current and finished choosing thickness or thinness, AUTOZ would program the processing conditions; (3) Intelligent programmed the conditions: only if choose the shape of electrode, the materials of both of electrode and work piece, the square of the electrode and choice size (thickness / thinness) of processed work piece when finished, the setting of depth, machine can program the processing conditions automatically.2009-2-20http://www.china-edm.com/20/77.htmWith 10 groups of automatic machining function and auto-shift from point to point. Providing 5 groups undulation setting function, the same one mold may establish 5 different undulation ways. With correcting automatically of electrode-consume, it can be setting the electrode-consume in advance when machining in the multi-hole.The computer will compensate the depth automatic so that each hole depth to be sonsistent. 2009-2-20
