1. Abrasive selection
The selection of abrasives for high-precision grinding machinesgrinding wheels is a kind of knowledge. The selection of abrasives mainly depends on the workpiece material and heat treatment method. When using high-precision grinding machines to grind materials with high tensile strength, you must choose toughness. When grinding materials with high hardness, abrasives with higher hardness should be used; when grinding materials that are not easy to be processed, abrasives that undergo chemical reactions should be selected.
Second, the choice of granularity
The particle size of the high-precision grinding machinegrinding wheel mainly refers to the particle size of the abrasive, which mainly depends on the surface roughness and grinding efficiency of the price to be ground. The particle size is mainly expressed by the particle size number. When grinding with a coarse-grained grinding wheel, the production efficiency is high. However, the surface of the ground surface is relatively rough; when grinding with a fine-grained grinding wheel, the surface roughness of the ground workpiece is better, but the productivity is very low.
3. Choice of hardness
High-precision grinding machineThe hardness of the grinding wheel refers to the difficulty of the grinding wheel falling off under the action of external force, which mainly depends on the workpiece material to be ground, the grinding efficiency and the quality of the processed surface. The abrasive grains will not fall off; if the grinding wheel is too soft, it will increase the wear of the grinding wheel and lose the correct geometry.
