1. Granularity selection
The smaller the particle size, the smoother the surface grinding. Of course, it is impossible to choose only one particle size, and the thickness should be combined.
2. Binder selection
There are three kinds of bonding agents: diamond, resin and ceramic bond.
diamond grinding wheel
Bronze binder is used, which has good formability, high strength and certain toughness, but poor self-excitation.
Resin bond grinding wheel
High strength, good elasticity, and stable bonding, but the resin is a polymer material with no fixed melting point, so the heat resistance is poor. When the temperature reaches above 200, the bonding ability is greatly reduced.
vitrified bond grinding wheel
High hardness, good self-excitation, stable chemical properties, heat resistance, water resistance, acid resistance, etc., and low cost, but the vitrified bond grinding wheel is powder pressed, so the uniformity is difficult to guarantee, and it is relatively brittle, so grinding Abrasive particles and binders tend to fall off collectively during processing.
In general, these three grinders have their own characteristics, and the needs depend on the actual situation.
