(5) The production and manufacturing process of abrasive tools requires furniture hardware accessories, and machine tool accessories should be considered in consideration of the differences in cold drawing (drilling, grinding and polishing, grinding) and heat treatment (forging, casting, welding) that need to be selected during production and manufacturing. The production and processing methods and processing techniques are consistent with the selection of appropriate raw materials. For the production of abrasives in different ways from hand-made and mechanical equipment, the selection of materials should be different. The cost of hand-made abrasives increases, and good raw materials should be selected as much as possible. Section 2 Cold-working Die Materials and Quenching and Tempering Cold-working Abrasives are abrasives used for working pressure production and processing of raw materials or other production and processing at room temperature. And forming dies, cold heading dies and cold extrusion dies. 1. The characteristics of various cold mining machinery parts as abrasives (1) The blanking die contains a knife edge, shears and presses during work, and separates the raw materials (mainly plates) to obtain a certain shape.
