Polishing and grinding of cemented carbide die tools

       

Ring viscoelastic abrasive polishing agent and equipment

Extrusion grinding and polishing need to use viscoelastic abrasive polishing agent, also known as viscous abrasive. It is uniformly mixed with abrasive and special flowing medium, and its performance directly affects the polishing effect.

At present, most of the extrusion grinding and polishing machines at home and abroad are of vertical opposed piston type. The movement of the two pistons forces the grinding and polishing agent to flow up and down. In addition to positioning and clamping, the fixture used for extrusion, grinding and polishing should also be able to contain and guide the abrasive and polishing agent through the parts that need to be polished and polished, and resist and interfere with the abrasive and polishing agent from flowing through the parts that do not need to be processed. . The fixture should be designed according to the shape, size and grinding and polishing needs of the processed parts
