Discharge parameters that affect the dressing efficiency, trimming precision grinding wheel dressing effect and the key factor in performance

Ultra-precision grinding wheel diamond powder is ultra-precision machining technology research focus . The use of diamond powder grinding wheel for engineering ceramics and other brittle materials for ultra- precision grinding , grinding and polishing  synthetic diamond  the need , not only to meet the machining accuracy and surface quality requirements , but also greatly improve productivity and reduce processing costs. Ultra- precision grinding wheel diamond powder one of the key technologies of diamond powder dresser . EDM trimming method is an cubic boron nitride metal bond diamond powder wheel approach. Diamond grinding wheel dressing spark experiments showed that: discharge parameters that affect the dressing efficiency , trimming precision grinding wheel sharpening effects and performance of one of the key factors , thus finishing with a spark pulse power is very important. A metal-bonded diamond powder  polycrystalline diamond  dressing spark pulse power requirements analysis , including wheel dressing shaping and sharpening two parts. Shaping its axis of rotation of the grinding wheel surface satisfy certain geometric relationships between , for flat grinding wheel grinding wheel is to ensure roundness and cylindricity . Dressing is to make the surface of the abrasive wheel protruding to form a sharp cutting edge and the chip space .
