1) The grinding process should ensure that the workpiece evenly touches all the surfaces of the lap. In this way, the surface of the grind tool can be uniformly loaded and worn evenly, and the surface accuracy of the grind tool itself can be maintained for a long time.
2) The grinding process of the drawing mold should ensure that the workpiece is evenly ground, that is, the grinding amount of each point on the surface of the workpiece should be the same. This is extremely important for ensuring the geometric accuracy and dimensional uniformity of the workpiece.
3) The grinding process should make the motion track change direction constantly and regularly to avoid premature repetition. In this way, many cutting streaks on the surface of the workpiece can be regularly intertwined to offset each other, that is, the more polished, the smoother and smoother, and then achieve the purpose of improving the surface quality of the workpiece.
4) The grinding process of the drawing mold should be selected according to the different grinding process requirements, and the best movement speed should be selected in detail. When grinding slender and large-scale workpieces, low-speed grinding is required; when grinding small-scale or low-precision workpieces, high-speed or high-speed grinding should be selected to increase the output power.
