About Fine Grinding:
High precision surface grinding or fine grinding is a super finishing process performed by removing material from two surfaces of a component resulting in extremely precise geometric accuracy and surface finish. Typically, it is the last grinding step of a mechanical production chain utilized to improve and/or correct the geometry of parts coming from sintering, sawing, molding or similar operations. Depending on the application, the stock removal also can be taken from just one surface.

When the machine is working, upper and lower grinding discs as well as the planet wheel rotate simultaneously to drive work pieces to do reciprocating planet motion between the two grinding plates. Various grinding materials such as super hard abrasive: Diamond grinding plates, CBN(cubic boron nitride) grinding plates; Conventional abrasives: Cast iron plates, GC plates, etc can be adopted for different requirements of various products, so as to achieve double side precision grinding on work pieces made from various materials. Our equipment take advanced probe side measurement and Sony size measuring controller to realize real-time online measurement control on processed work pieces.
