Rough grinding method, using 600 ? abrasive belt to grind the workpiece on three sides. The goal of this process is to remove the solder joints left by the workpiece welding, and the bumps presented in the previous process, and reach the initial formation of the weld fillet. The horizontal and vertical planes are basically free of large scratches and bumps. After this process, the surface roughness of the workpiece should reach r0.8mm. Attention should be paid to the inclination of the abrasive belt machine and the pressure of the abrasive belt machine on the workpiece. Generally speaking, to be thrown into a straight line with the surface is more moderate!
Semi finish grinding, grinding the three sides of the workpiece with 800 ? abrasive belt according to the previous method of reciprocating grinding, mainly correcting the joints presented in the previous process and further fine grinding the marks after rough grinding. The marks left by the previous process should be repeatedly ground until there is no scratch on the surface of the workpiece and it is basically bright. The surface roughness of this process should reach r0.4mm. (note that no new scratch or bruise is allowed in this process, because such defects cannot be repaired in later processes.)
