What is Abrasive Machining? Advanced Manufacturing
Feb 01, 2010 · Not only is the grinding wheel held continuously in a constant state of maximum sharpness, but the form is accurately maintained. The level of sharpness of the grinding wheel is such that stock removal rate could increase by a factor of 20 or more over conventional grinding, even in the most difficult-to-machine nickel and cobalt-based superalloys.
What Hazards Are There When Using a Grinding Wheel? eHow
Harder wheels are used for grinding or sharpening high-strength steel like cutting tools and drill bits. Cutter grinding wheels are used for cutting steel casings, steel plate, rods or sheet metal. Using the wrong wheel can cause the wheel to wear too quickly and become unbalanced or fall apart.
Profile grinding is employed to grind various precision moulds such as die & punch for press which have complicated forms of irregular lines and curves, forming cutting tools, cutting tools, high precision plate gauge, electrode for electric discharge grinding and formed precision parts such as template.
