3) Grinding of tungsten steel fittings should make the movement track change direction regularly and avoid premature repetition. In this way, the numerous cutting strip marks on the surface of the workpiece can be regularly interlaced and offset, that is, the smoother the grinding, so as to improve the surface quality of the workpiece.
4) The grinding process of tungsten steel fittings should be based on different grinding process requirements, and the optimal moving speed should be selected. When grinding slender large-sized workpieces, low-speed grinding is required. When grinding small-sized or low-precision workpieces, speed or high-speed grinding is selected to improve production efficiency.
