sandpaper belt grinding of pre-history

 Sandpaper belt grinding pre-history are the following:1, sandpaper belt to complete the function of the effect is the effect of grinding: the use of sandpaper sizes, fine sand strange grinding on ceramic belt  demand goods, so that the product of increasingly sophisticated, increasingly silky. About 3M sandpaper belt grinding function of the deposition of another long before history was not special, but it is very tough to carry out.
So accustomed to all kinds of new materials, parts grinding. Grinder and wheel types, functions has also been further carried out. Fundamentally cut off wheel  based on the type of out 10 series, fine precision type, semi-automatic, inclined wheel type, NC, wide wheel-type, multi-piece wheel-type, high-speed, multi-wheel frame type, strong grinding type.
2, and a variety of modern machinery processing carried out the presentation of new material
 Ongoing follow modern machining and various new materials continue to show its precision roughness pleading looks increasingly high, the corresponding loss of various grinding points to continue to  abrasive tools show ongoing satisfaction of modern industry these years, 3M sandpaper belt grinding skills are moving in this direction to carry out research, development and use of new, superhard abrasives development and implementation of ultra-fine grinding and efficient grinding process and development, application in high-precision, high rigidity grinder and grinding.
