This process is known as thermal expansion. Though the expansion can be very minute, it can still adversely affect size-sensitive applications such as precision grinding. Why Does Thermal Expansion Occur? In grinding applications, the high surface tension between the precision grinding machines and the substance produces heat due to friction.
For surface grinding operations, the process parameters, i.e. the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground surface.Higher values of any of them would result in a higher material removal rate, and therefore, a higher rate of generation of thermal energy.
In the working process of the large gear grinding machine, thermal deformation occurs under the combined action of internal and external heat sources, which affects the relative position between the workpiece and the grinding wheel, and reduces the gear processing accuracy. Studies have shown that in precision machining, the proportion of ...

absence of thermal damage can be achieved. HEDG can achieve low specific grinding energy compared with shallow grinding and creep grinding. The chips take away most of the heat generated in the grinding process. As in creep grinding, bum-out of the coolant causes a steep rise in contact temperature of the workpiece. 1 Introduction
