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.

Abrasives museum--the earliest of grinding or abrasives tools

Recently, Abrasivesman- Xiao did a business trip in somewhere during he visited a local museum and discovered the earliest of abrasives and sanding tools The Photo-1 showed that this is kind of special grinding tool that this is grinding broken of tool. grinding objective may be stone. The photo-2 is a types of abrasive or polishing tool and its shape likes a plate; the grinding objective was on the top and then through use hand sanding. According to this abrasives'museum of introduction, these abrasives or grinding tools have over 2000 years
