Background technology
With the development of the technologies such as liquid crystal panel manufacture, optic communication, automobile making, to associated grinding and polishing field
Requirement also more and more higher.
In TFT-LCD field of liquid crystal panel manufacture, as panel pushes more advanced lines and touch screen technology to increasingly
Widely use, the glass that panel is used also increasingly thinning, increasingly high intensity.In terms of liquid-crystalline glasses thinning, large scale
Ultra-thin glass due to the high request that transports and expensive cost, current liquid crystal panel enterprise using compared with heavy sheet glass, in enterprises
Reuse after thinning is processed.And the thinning mode of glass, traditional CMP planarization mode, as its substantial amounts of lapping liquid disappears
Consumption, liquid waste processing and working environment liquid splash are seriously polluted, are gradually polished progressively by free lapping liquid before
Trend uses bonded abrasive tool abrasive material, and this can not only greatly save grinding consumptive material, and the pollution to environment is also greatly reduced, workshop
More neat and tidy, grinding efficiency are also greatly improved.And the panel in liquid crystal panel manufacture process before Cell back segments patch polaroid
In terms of cleaning, currently widely used cleaning abrasive cloth, is ground due to its relatively low life-span and inevitably because of abrasive material
The scuffing that bits are piled up and cause panel to cause, can largely affect the bending strength of panel.
In optical communication field, light has become the requisite part of optical fiber communication technology application without source connector, with
Fiber-to-the-home popularization, optical communication product will have larger growth.But just restrict a key factor of its cost and quality
It is the end surface grinding of optical fiber, the quality and the height of cost of its face machined flat directly govern the application and popularizations of this product.
The painting subordinate class pouncing paper for being used at present, relatively low service life and abrasive dust are piled up the grinding scuffing for causing and greatly be have impact on
The production efficiency of optical fiber class product.
In automobile manufacturing field, the parts of automobile include the grinding and polishing of various axles, roller, and the polishing of body of a motor car is thrown
Light, lacquer painting are repaired etc., and the grinding consumptive material consumption for being used is very big, traditional plant sand product in use due to its compared with
Low service life, the discordance of grinding and polishing, to using bringing larger inconvenience.
More than it is a variety of illustrates invariably, it is a kind of with higher grinding force, good ground effect and grinding effect can be kept
