Polishing Wax Hand Grinding and Mechanical Grinding Characteristics The main components of polishing wax: stearic acid, palmitic acid, oleic acid, rosin and other adhesives, plus abrasives, such as feldspar powder, chromium oxide, corundum, iron red, etc., according to different matrix components and requirements. Fineness and variety. In daily production, polishing wax is used for polishing, and we usually divide it into manual grinding and mechanical grinding according to the operation mode. According to the way of coating abrasives, it can be divided into dry grinding, wet grinding and semi-dry grinding. Manual grinding is mainly used for single piece small batch production and repair work. Manual grinding is labor-intensive and requires skilled operators and high technical skills. However, manual grinding is indispensable for some high-precision workpiece processing. Mechanical grinding is used in mass production, especially when the workpiece geometry is not complex. Mechanical grinding is often used. Polishing wax dry grinding is also known as embedded sand grinding. Before grinding, the abrasive should be embedded on the surface of the grinding tool (referred to as pressed sand). When grinding, just apply a little lubricating oil on the surface of the grinding tool to carry out the grinding work. Wet grinding is also known as sand-applied grinding. Before grinding, a pre-prepared liquid grinding mixture is applied to the surface of the grinding tool, or the grinding mixture is continuously added to the surface of the grinding tool during the grinding process for grinding. Semi-dry grinding is similar to wet grinding in that a paste-like polishing wax is applied to the surface of the grinding tool for grinding before grinding. Wet grinding has higher productivity. Whether it is manual grinding, mechanical grinding, or dry grinding and wet grinding, the quality of the workpiece to be ground mainly depends on the grinding method, abrasive, additional abrasive, grinding pressure, grinding motion and pre-processing before grinding and other factors. Grinding is widely used.
