The tungsten carbide die tooling grinding movement should be satisfied with the following points

       

 1) The grinding movement 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 movement of the drawing die should ensure that the workpiece is evenly ground, that is, the grinding amount of each point on the surface of the workpiece to be researched should be the same. This is extremely important for ensuring the geometric accuracy and dimensional uniformity of the workpiece.

 

   3) The grinding movement should make the movement track constantly and regularly change the direction to prevent 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 movement of the drawing die 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.

 

   5) The entire grinding movement should be stable from beginning to end, especially for the grinding area and slender workpieces, and more attention should be paid to slow changes in the direction of movement to prevent small bends, and the direction of movement should be as far as possible to the long side of the workpiece. Neglect the speed of movement. Otherwise, the unevenness of the movement will cause unevenness in the surface of the researched, or quality defects such as falling edges and corners.

 

    6) During the grinding movement, the grinding tool and the workpiece should be in an elastic floating condition, rather than a forced limit condition. In this way, the surface of the workpiece and the lap can be better touched, and the shape of the lap can be accurately transferred to the workpiece.

 

   Commonly used manual grinding motion forms include straight line, cycloid, spiral box imitating "8" shape and so on.
