Investigation of surface temperature in high-efficiency deep grinding

摘要

A new thermal model with triangular heat flux distribution is given in high-efficiency deep grinding. The mathematical expressions are driven to calculate the surface temperature. The transient behavior of the maximum temperature on contact area is investigated in different grinding conditions with a J-type thermocouple. The maximum contact temperatures measured in different conditions are found to be between 1 000 deg C and 1 500 deg C in burn-out conditions. The experiment results show good agreement with the new thermal model.
