plane grinding and polishing technological development of trend

Grinding machining technology is a kind of  mechanical processing method , which has a long history in the abrasives applying of filed.Usually abrasives method is refers to the use of hardness is higher than by processing materials micron grade of abrasive, the hard grinding plate under the action of the micro cutting and rolling to plunge into action, realize the processing surface trace material removal, the shape, size precision of the workpiece up to par value, and reduce the surface roughness, reduce the machining quality layer. Polishing is a concept often associated with grinding. Polishing refers to the use of high-speed rotation of low elastic materials (cotton, MAO yue, artificial leather, etc.) polishing disc, or use of low-speed rotation of soft elastic or viscoelastic materials (plastic, leek, stone, tin, etc.) polishing disc, with a certain abrasive nature of the polishing agent, so as to obtain a smooth surface processing method.In short, in addition to the choice of abrasive and abrasive materials, grinding and polishing no essential difference.
