The double-sided grinding machine is a grinding machine that applies or embeds abrasives to grind both sides of the workpiece. It can simultaneously grind and polish the front and back of the workpiece at one time; let's take a look at the following Grinding machine processing method:
1. Dry grinding: Only a small amount of lubricating additive should be coated on the surface of the grinding tool during grinding. The sand particles are basically fixed on the grinding tool during the grinding process, and its grinding function is mainly sliding grinding. This method has low productivity, but can achieve high processing accuracy and small surface roughness values (Ra0.02 ~ 0.01μm).
2. Wet grinding: During the grinding process, the abrasive is coated on the grinding tool, and the dispersed sand particles are used for grinding. In addition to grit, abrasives include kerosene, motor oil, oleic acid, and stearic acid. During the grinding process, some sand particles are present between the grinding tool and the workpiece, as shown in Figure 8-12b. At this time, the sand grains are mainly rolled and the productivity is high. The surface roughness Ra is 0.04 to 0.02 μm. It is generally used for rough processing, but the processed surface is generally matte.
3. Soft abrasive grain grinding: During the grinding process, the abrasive using chromium oxide as the abrasive is coated on the working surface of the grinding tool. Because the abrasive is softer than the grinding tool and the workpiece, the abrasive is suspended between the workpiece and the grinding tool during the grinding process The chemical action of the abrasive and the surface of the workpiece is mainly used to produce a very soft oxide film. The thin film at the bumps can be easily removed by the abrasive.
