Description
Principles and processes of high-precision surface grinding:
High precision surface 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.
Xinxiang SKF Machinery Co., Ltd. has focused on researching and developing high-precision grinding technologies of single sided and double sided grinding machines for many years. We hope to share rich process experiences and technological achievements with users.
Flatness:
Work pieces’ flatness depends on flatness of lapping plate.
Roughness:
Surface roughness depends on size and shape of abrasive grains and plates’ materials, as well as material and hardness of work pieces.
Rough grinding:
Grinding on plates and surface of work pieces with the use of coarse grinding plates, with large amount of feed and high efficiency; however, grinding surface is relatively rough, and apply to those with many lapping allowances.
Fine grinding:
Grind on plates and surface of work pieces with the use of fine grinding plates, with small amount of feed and good surface smoothness; lapping mark are uniform and fine.
