In recent years, with the development of the machinery industry, grinding has gradually become mechanized. Grinding is a finishing process in the processing of mold parts. Grinding is usually carried out manually. Abrasives are added between the grinding tool and the grinding surface to grind a very thin metal layer from the surface of the part, so that the workpiece can obtain a high-precision and high-finish surface.
General classification of mold parts grinding:
- 1. Wet grinding: It is also called sand-coated grinding. The liquid abrasive is continuously injected or coated on the grinding surface. The abrasive continuously slides and rolls between the workpiece and the grinding tool to form a cutting motion. Wet grinding is generally used for rough grinding.
- 2. Semi-dry grinding: similar to wet grinding, the abrasive used is paste grinding paste. Grinding can be done manually or on a grinding machine.
The characteristics and purpose of mold parts grinding:
The general grinding is mostly manual or semi-manual operation, its equipment is simple, the operation is convenient, the cost is low, and the maintenance is easy. The purpose of grinding is to:
- 1. Improve the surface finish.
- 2. The processing equipment is streamlined and the accuracy requirements are not high
- 3. Obtain precise dimensions and precise geometric shapes.
- 4. After grinding, the surface finish of the mold parts is improved, so that the corrosion resistance and wear resistance of the parts are significantly improved.
