1. Test method Discrete abrasive grinding was carried out on a planetary double side grinder as shown in Figure 1. Among them: the upper and lower grinding discs are made of cast iron, copper, tin-lead gold, and napped leather. In order to improve the grinding efficiency, a thread or a rectangular groove is machined on the metal grinding disc. The movement speed can be variable frequency stepless speed regulation, and the cylinder output force (ie, the grinding pressure) can be adjusted by controlling the pressure of the decompression crucible. The diamond abrasive used has W2 8 , 1 4 , W7 , W 3 , WI micropowder. The consolidated abrasive grinding was carried out on the improved single-sided grinder shown in Figure 2. The workpiece is adhered to the surface of the grinding disc by a wax, and the abrasive sheet is adhered to a planetary wheel rotatable about its own axis by an adhesive, and the grinding pressure is adjusted by controlling the cylinder pressure. The rotation speed of the grinding disc can be variable frequency and stepless speed regulation. The particle size of the diamond grinding disc is: W2 8 , W1 4 , w 7 , W3 , Wl , the bonding agent has bronze junction, the resin binder, the concentration is: 7 5 %, 1 0 0%, 1 5 0%. The workpiece was cleaned with an ultrasonic cleaner before and after grinding. On the fine balance, the weight before and after grinding, the thickness measurement of the measuring piece and the grinding piece by the precision micrometer are measured. The mechanical surface renting degree (JII) before and after the grinding is measured, and the defective rate in the grinding is counted. 2. Test results: analysis of the mechanism of 噩 The ratio of (G) and mortar (O) is greater. The larger the surface roughness of the workpiece after grinding, the stronger the ability of the abrasive to roll the workpiece and cut. The amount of grinding is also larger, and the fine particles do not function in the grinding. Placed in the grinding (especially in the fine grinding) The three-dimensional size of the selected diamond powder is as uniform as possible. The polycrystalline diamond powder produced by DuPont is used in this experiment. The polycrystalline diamond powder is more than single crystal. The diamond micropowder is closer to a spherical shape and has a better grinding effect. It can also be seen from the consolidation of abrasive grinding that the improvement in roughness is at the expense of reducing the grinding ratio of the abrasive sheet, and that the reduction in grinding ratio is much greater than the extent of surface roughness improvement. Therefore, under the premise that the surface roughness can be satisfied, the coarse micropowder is used as much as possible or the coarse grinding is performed after the coarse grinding to solve the contradiction between the abrasive consumption and the final surface quality of the workpiece.
