Ultra-fine grinding and polishing is a special-purpose grinding tool. In the polishing liquid containing abrasive, it is pressed against the machined surface to perform high-speed rotary motion. With this technology, the surface roughness of Ra0.008 μm can be achieved, which is the best surface roughness in various polishing methods.

Sep 08, 2021 Ultra-fine diamond powder is an ideal abrasive for ultra-precision grinding of hard and brittle materials. 15 The hardness of diamond is higher than that of ordinary hard brittle materials. Compared with other abrasives, diamond abrasives can invade the surface of workpiece with less pressing force, resulting in mechanical removal.

The work demonstrates the utilization of fractionalized lignin from the black liquor of soda pulping for the development of starch-lignin biocomposites. The effect of ultrafine friction grinding on lignin particle size and properties of the biocomposites was investigated. Microscopic analysis and membrane filtration confirmed the reduction of lignin particle sizes down to micro and ...
