Analysis of the results of the finishing process for manufacturing low-hardness products from non-metallic structural materials

Abstract

Abstract The methods and results of glass processing, including quartz glass, are considered. Research is aimed at improving the quality of the surface in the physical and chemical methods of exposure to the product, to ensure high precision machining and surface quality without cracks and scratches. Processing was applied to rotation bodies. Polyurethanes with solid inclusions were used as a polishing tool. The parameters of solid inclusions are investigated and their influence on the quality of the surface obtained is evaluated. The results of the study were obtained for the operations of grinding, polishing and etching quartz glass samples with different processing modes. The influence of these processes on the value of the surface roughness parameter of silica glass is estimated. It has been established that the quality of the glass surface during processing is affected by geometry and surface roughness before processing; the quality of the polishing tool, the etching mechanism; time and modes during polishing, as well as the effect of the polishing slurry. In the process of polishing and etching, the division into conditional boundaries of the treatment zones occurs. The formation of roughness and macro geometry is due to the polishing scheme, the size, and geometry of the tool, as well as the accuracy of the alignment of the machine. The results of the study are clearly presented, the obtained data of experiments on polishing and pickling are analyzed, conclusions are made in this work.
