The honing temperature of a cylindrical workpiece of steel is investigated both experimentally and theoretically. The experiment is carried out by using a vertical honing machine consisting of a constant pressure stone system. The temperature distribution in the workpiece is measured by means of a thermocouple formed by spot welding at the bottom of a small hole. The influence of its temperature on the finishing accuracy is also studied. The results obtained are as follows. The change of the cutting condition of sticks can be found from the variation of temperature in the surface layer of a workpiece. On the distribution of temperature in the workpiece, its gradient in the radial direction is small, but that in the axial direction is not so small. Using the suitable model of honing operation, the theoretical equations representing the influence of honing conditions on the temperature of workpiece were obtained. These equations explain the experimental result well. For example, the temperature becomes larger in proportion to the honing speed and the stone pressure, and the heat flux into the workpiece decreases as operation proceeds.
