May 12, 2009 · Never lay the grinder down until the wheel has come to a complete stop. (Grinders with electric or mechanical brakes minimize the waiting time.) Be sure the switch properly turns the grinder on and off. If not, do not use the tool until necessary repairs are made. Ensure that the grinder is unplugged before mounting or removing a wheel.

Size Reduction by Grinding as an Important Stage in Recycling 275 for example, -edge grinders characterized by low energy consumption, low noise level and good repeatability of grain classes [4, 13]. Cutting between two cutting edges is widely used in cutting mills, in particular for grinding of plastics and cross-linked elastomers [48, 3].

Grinding operations thus contribute greatly to the quality of the finished workpiece. However, problems can often occur during the grinding process. The biggest and most known problem is without doubt grinding burn, which is thermal damage to the rim zone of the part. Grinding burn occurs when too much heat is channelled into the part.

Instead of the work being supported between centers, as in the older cylindrical grinding, it is supported by means of contact with the grinding wheel, the regulating wheel, and the work blade. In this paper, the methods of analysis already developed and used to examine other machining processes [1, 2] are extended and applied to centerless grinding.
