Q What are the differences between slow-speed Wire EDM and fast-speed Wire EDM？
A – The wire travel speed is different. The fast wire travel speed is 8~10m/s, and the slow wire travel speed is 0.001~0.25m/s.
– Wire material is different. The electrode wire material of fast-moving wire is molybdenum, tungsten-molybdenum alloy, and the electrode wire material of slow-moving wire is brass wire and copper-based plating material.
– The working fluid is different. The working fluid of a fast-moving wire is an emulsion, and the working fluid of a slow-moving wire is deionized water or kerosene.
– The processing speed is different. The processing speed of fast wire is 20~16mm2/min, and the processing speed of slow wire is 20~240mm2/min
– Different precision. The processing accuracy of fast wire is 0.01~0.04mm, and the processing accuracy of slow wire is 0.004~0.01mm
-
Q What are the machining advantages of WEDM？
A – High machining accuracy. 0.01mm electrode wire can be used, and the highest precision can reach 0.001mm
– High surface quality. The surface roughness can usually reach Ra=0.8μm and above.
-
Q What materials do Wire EDM process
A As long as it is a conductor or semiconductor, it can be processed regardless of the hardness of the workpiece material.
