Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.

Answer: Depends on wich hardness you are talking about. Wheel hardness is not the same as the hardness of the abrasive grain. But as for why you would need a harder wheel for soft materials.(steel, stainless steel, rubber, plastics, wood, carbon etc.) Theoretically this is because the softer ma...

When you change material, your grinding technique can change. For instance, because stainless steel conducts heat the way it does, a grinding wheel can heat up and blue the metal surface before you know it. If it's a cosmetically important area, you may need to go back and regrain or polish the entire surface.

This grinding is done wet or dry, depending on the process in use, but for dry grinding the raw materials first may need to be dried in cylindrical, rotary dryers. Read More; In cement: Grinding.

The first consideration is the material to be ground. This determines the kind of abrasive you will need in the wheel. For example, aluminum oxide or zirconia alumina should be used for grinding steels and steel alloys. For grinding cast iron, non-ferrous metals and non-metallic materials, select a silicon carbide abrasive.

We then grind it down and pass it through a series of ferrous and nonferrous metal detectors, along with magnets, to guarantee that the finished material is free of contaminants. What It Means to You Now that you know what regrind is, let's talk about why you should care.
