Wire EDM Machining

Jan. 23, 2020

At present, the Wire Cutting EDM Holes Machine has a more precise structure. In order to ensure high-precision processing, many technical measures have been adopted to improve the accuracy of the host: temperature control. The water temperature cooling device is adopted to make the internal temperature of the machine tool the same as the water temperature and reduce the thermal deformation of the machine tool. Use linear motor. High responsiveness, precise positioning can achieve 0.1m equivalent control, feed without vibration, noise, increase the discharge frequency, maintain stable discharge, cut Ry5m twice. Made of ceramic and polymer artificial granite, its thermal inertia is 25 times greater than that of cast iron, reducing the effect of temperature changes on cutting accuracy. The wire cutting machine adopts a fixed table and a column moving structure, which improves the bearing capacity of the table and is not affected by immersion processing and changes in workpiece weight. Using immersion processing to reduce thermal deformation of the workpiece. Motor servo, closed loop electrode wire tension control. High-precision tool setting: using voltage modulation tool setting power. Tool setting accuracy can reach ±0.005mm without damaging the workpiece, whether it is wet or dry.

In the middle of the 20th century, when the lazarinkos of the Soviet Union studied the phenomenon and cause of corrosion damage of switch contacts by spark discharge, they discovered that the instantaneous high temperature of electric sparks could cause local metals to melt, oxidize and be corroded, thereby creating and inventing electricity. The spark machining method and wire-cut electric discharge machine were also invented in the Soviet Union in 1960. At that time, a projector was used to manually feed the work surface to the front and back after viewing the outline. In fact, although the processing speed is slow, it can process fine shapes that are not easy to be processed by traditional machines. A representative practical example is the processing of special-shaped holes for chemical weaving nozzles. Mineral oil (lamp oil) for processing fluids used at the time. High insulation, small distance between poles, processing speed is lower than the current machinery, limited practicality. NC-based, machine models processed in deionized water (close to distilled water) were first exhibited by the Swiss EDM factory at the 1969 Paris Machine Tool Exhibition to improve processing speed and establish safety in unmanned operation . However, the production of NC paper tape is very troublesome, and it will be a great burden on the user if automatic programming of a large computer is not used. Before the introduction of cheap automatic programming devices, their popularity was slow. Japanese manufacturers have developed wire-cut electrical discharge machining machines designed with a small computer automatic program that is inexpensive and has accelerated its popularity. The machining shape of the WEDM is a two-dimensional contour.
