DOUBLE SIDE FINE GRINDING MACHINE
Main Purpose:
Double side fine grinding machine is an automatic high-efficiency machine that is suitable for batch processing of parts. It can achieve 0.002mm flatness & parallelism and surface finish up to 0.1 Ra. It is widely used for grinding and polishing the surface of parts, using CBN grinding wheels, diamond grinding wheels, diamond grinding pads to achieve efficiently and accurately double-surface grinding and thin processing for metal and non-metallic hard & brittle materials such as hydraulic and pneumatic components, automobile fuel pump components, refrigeration compressor components, oil pump components, engine components, seals, piston rings, measuring tools, carbide blades, ceramic valve, cutting tools, magnetic materials and other products.

FINE GRINDING PROCESS
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.
