THE EFFECT OF TEMPERATURE ON THE GRINDING SURFACE QUALITY RING ROLLER

Abstract

A series of experimental researches was carried out in the work, which confirmed the results of modeling of temperature processes in the zone of centerless intermittent grinding of billet rings. The constructed response surfaces of the dependence of the roughness parameter Ra on the grinding modes and the number of grooves of the grinding wheel form the basis of the developed technique for designing grinding operations and tool adjustments of grinding machines. The contact area of ​​the abrasive circle with the workpiece is a narrow strip of rectangular shape that moves along the workpiece surface. In this case, the temperature field can be calculated according to the scheme of a moving infinitely long surface-band source. The plan, the program and the hardware of experimental researches of the connection of design and technological factors and indicators of grinding operations with parameters of quality of grinding surfaces, temperature of grinding, power parameters of the process of grinding by discontinuous grinding circles and constructive circles have been developed.
