edm
Edm is suitable for machining complicated parts such as small cavity, narrow gap, groove and corner.The edm process is superior to the milling process where deep cutting is required and the aspect ratio is particularly high when the cutter is difficult to reach the complex surface.For the machining of high technology parts, redischarging of the electrode by milling can improve the success rate.In addition, where an edm finish is specified, edm is provided to provide the surface of the flame pattern.
With the rapid development of high-speed milling, the development space of edm has been squeezed.At the same time, high - speed milling also brings greater technological progress to edm.For example, high-speed milling is used to make electrodes. Due to the realization of small area machining and high quality surface results, the number of electrodes is greatly reduced.In addition, manufacturing electrodes with high-speed milling can also improve the production efficiency to a new level, and ensure the high precision of the electrodes, thus improving the precision of edm.If most of the machining of the cavity is done by high-speed milling, edm can only be used as an auxiliary means to clear the Angle and trim, so that the amount is more uniform and less.
A precision discharge motor with a machining area of less than 20 square centimeters can achieve mirror spark machining of Ra<0.1 micromm and uniform matte surface and all levels of grain surface machining.For a micro part, such as a connector, the result of a clear Angle less than 0.02mm and machining accuracy less than 5 mm is available.Technology of expert system of machine tool, and in the popular process, intelligent discharge parameters generated excellent processing results can be realized, for the discharge of special and complex components, provides the specialized technology module, such as IC, leds, connectors, large cavity, narrow gap, RSM surface, etc., the optimization of the process are the integration of expert experience.In the case that the machine tool is equipped with a fast clamping positioning jig and an automatic electrode replacement device, it can be automatically discharged for a long time without humanization.
