materials that can be grinded

What Are Static

These materials are typically used to prevent discharge to and from human contact. The body is a high conductor of energy and can easily create a static spark. A plastic static-dissipative material causes that spark to flow slower, emitting a lower energy to the ground to prevent discharge and possible damage to any sensitive items. Get price

Is it Safe to grind aluminum, or not?

2004. A. My experience is the bonded abrasive (grinding wheel) composition may be compromised by the heat generated by a clogged wheel. The heat is usually carried away from the wheel in the metal it removes, but a clogged wheel becomes a heat generator and the metal adhered to the wheel seals the heat in, therefore you could see a wheel explosion when the material is in contact with the wheel.
