electron discharge grinding

It is widely believed that the cylindrical grinding which is required to shape the boule to its final diameter, introduces damage below the machined surface. This subsurface damage, which can easily extend 50-70 microns into the material, triggers microcracking along the edge of the wafer. ... small footprint wire electron discharge machine ...

Module 04 Electron Discharge Machining

Electrical Discharge Machining ... The grinding action of the paste gradually shaped the die cavity to its final form, but the process was time consuming. With EDM, the total time required to produce a die is greatly reduced. Hand polishing with diamond paste is still necessary, but only as the final finishing step. ... Learn More
