Cooling fixed abrasive grinding discs
2015-07-14 by bridge
This is the kind of cooling bonded abrasive discs silicon, sapphire, ceramics, and glass and other materials used for one-sided or double-sided polishing. Internal
grinding discs having coolant circulation passage, grinding disc containing a porous abrasive grinding block, a substrate having a plurality of channels and opened a center hole and trench manifold components. Each porous grinding block through the end of the adhesive fixed on a substrate of a pore, porous grinding blocks in large pores communicate with each other. Manifold central bore manifold grooves, radial grooves and the base manifold channels and a porous grinding blocks constituting the large pores in the coolant circulation channel. Grinding disc of the present invention has an inner cooling circulation passage, can enhance the cooling effect, can effectively prevent burns grinding plate and the workpiece, high dimensional accuracy of the workpiece surface roughness is good.
