Abstract
At first, the detective method of grinding burn was studied. Next, many tests were performed in surface grinding to study the effect of grinding conditions on grinding burn. Finally, the nature of grinding burn was discussed from these experimental results.
The main results of experiments are as follows.
(1) The detective method of grinding burn by means of reflectional rate changes was employed successfully.
(2) It was recognised that the nature of grinding burn highly depended upon the maximum temperature θm at the work-wheel contact surface. On the other hand, the effect of heating time was recognised little.
(3) The critical occurring condition of grinding burn was given by the following equation.
θm≥const
Now, this constant value was about 500°C in surface grinding of SKH 4 A high-speed steel with A 80 NmV wheel.
(4) The effect of treated wheel (wax) on grinding burn was recognised little.
