Background technique

The so-called form grinding is to decompose the complex forming surface into several simple surfaces, such as plane, cylindrical surface, etc., and then grind in sections to make the connection smooth and round, so as to meet the requirements of the drawing. Form grinding has the advantages of high precision and high efficiency. It can finish the hardened punch, assembled die, etc., and can eliminate the influence of heat treatment deformation on precision, thereby improving the manufacturing accuracy of molds. At the same time, form grinding Cutting can reduce the workload of the fitter and improve production efficiency. In the manufacture of injection molds, it is the most commonly used and most effective processing method at present to use the method of forming grinding to finish the punch, die and parts of the punch and die.
