Planar Grinding Stones | Buehler
For grinding or cutting carbon steel, high speed steel, tool and die steel and other high alloy, high tensile strength materials. Silicon Carbide Grinding Stone A very hard, sharp abrasive grain. Used in grinding of cast iron, aluminum, copper, bronze and non-metallic materials such as plastic and glass.The oldest machining process - at the beginning of “Stone,,“Stone Era”. •Free sand was applied between two moving parts to remove material and shape the stone parts. Grinding: •Removing of metal by a rotating abrasive wheel. (Very high speed, Shallow cuts) •the wheel action similar to a milling cutter with very large number of cutting points. •Grinding was first used for making tools and arms.Grinding Aluminum,The stone would grind the aluminum for a while, but particles would start getting embedded in the pores of the stone. And the next time the stone comes around, there's no grit exposed, only little bits of aluminum. So the aluminum on the piece rubs against the aluminum on the wheel, producing more heat, which produces more melting, and so on.
