What is the speed of the polishing wheel when polishing different metal materials?
When polishing, the peripheral speed of the polishing wheel should be higher than that of the polishing wheel. The circumferential speed of the polishing wheel should be different for different metal materials.
The best circumferential speed of pig iron, copper and nickel is 30~35m/s
The best circumferential speed of copper, copper alloy and silver is 22~30m/s
The best circumferential speed of aluminum and aluminum alloy, zinc, tin and lead is 18~25m./s
