Abstract：

Based on the actual working condition that the forging manipulator clamping the thermal parts, the friction pairs were made by jaw material ZG310-570 or HT350 with other common materials. The friction coefficient of the friction pairs at normal temperature and in the process of the sample block temperature decrease were tested by the transformed M-200 type friction and wear tester. The experimental results show that the friction coefficients of the ZG310-570 pairs are smaller than that of the HT350 pairs and the friction coefficients increase with the decrease of the sample block temperature. Therefore, when designing of clamping apparatus, it is more reasonable to choose the friction coefficient between jaw and thermal parts according to the friction coefficient at high temperature.
