Sandwich rubber elastic wheel/Sponge polishing elastic wheel special for polishing copper,aluminum alloy, stainless steel

Grinding characteristics of copper and aluminum alloys

Aluminum alloy has been used more and more widely in the defense industry, electrical industry, instrument industry and other sectors.

The requirements are getting higher and higher. Both of these materials are highly ductile materials with low hardness (generally HB40-60, the thermal expansion coefficient is 1.53 times that of carbon steel: the thermal expansion coefficient of aluminum is 1.98 times that of carbon steel), and both have high Plasticity, so the following phenomena often occur during grinding:

(1) The grinding shoulder is easy to block the grinding wheel;

(2) The surface of the workpiece is easily scratched and the roughness is low;

(3) The workpiece is easy to deform;

(4) Low grinding efficiency.

In order to overcome the many disadvantages that copper and aluminum alloys are prone to, it is necessary to choose abrasives with good thermal conductivity, high brittleness, and coarser particle size. A grinding wheel with loose hardness structure and higher hardness of the binder. The elastic wheel is the best choose.

Usage of elastic wheel:It is widely used for polishing the cooper,aluminum alloy and stainless steel.

The hardness of the elastic wheel can be adjusted according to the requirement.
