Understanding the causes of grinding burn helps

2003-1-30  During grinding, a great deal of heat is generated. This heat penetrates the workpiece. As the temperature rises, the hot surface of the workpiece s u r f a c e being ground wants to expand upward and outward (Figure 1). The upward thermal expansion is unrestricted. However, the surrounding material re stricts the outward thermal expansion.
