Description
Technical field
Hard brittle material grinding and polishing technical field is the utility model is related to, more particularly to a kind of concretion abrasive refiner discs.
Background technology
Plane lapping technique be workpiece planarization/polishing must be through technique.By mechanical lapping can make workpiece surface cut and
Spot is able to remove and obtains uniform relatively low surface roughness.Hard brittle material plane lapping method have free abrasive grinding and
Two kinds of lapping modes of solidified abrasive grinding.By abrasive material be prepared into that fluid slurry is ground for free grinding；Abrasive material is used viscous
Knot agent is fixed, and the mode that the raised abrasive material of abutment surface is ground is ground for consolidation.For free type grinding, consolidation grinding
Mode is higher to the utilization ratio of abrasive material, not only saves a large amount of expensive abrasive materials (such as diamond), also reduces liquid waste processing
Work, and the cleaning of workpiece or equipment, simplify processing technology.
Abrasive size and the proportional relation of workpiece target roughness, it is thick with the less abrasive lapping of particle diameter, the surface of acquisition
Rugosity is smaller, but material removal efficiency is low, and vice versa.Therefore, plane lapping is divided into corase grind and fine grinding twice technique, first with thick

Class mill is using the particle diameter of abrasive material in 1~10um.For concretion abrasive refiner discs, it is necessary to apply very big pressure just to workpiece
It can realize that material removes, such as 2~5kg/cm2.Specifically a 9B milling apparatus (grinding dish external diameter be 600~
700mm), 2 cun of sapphire sheets of batch processing 35 piece are, it is necessary to apply 1.4~3.5 tons of pressure, high precision plane milling apparatus without
Method applies so big pressure, and excessive pressure easily causes erratic star wheel to damage and be ground workpiece chipping.
To sum up, existing plane lapping equipment has the problem of can not being ground under big pressure condition to workpiece.
