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℃ and 1 500℃ in burn-out conditions.The experiment results show good agreement with the new thermal model.
