一种变向研磨摩擦试验机的研制

The Development of Friction Tester Adopting of Changing-di-rection Lapping

研制了一种能更好地模拟实际研磨工艺的变向研磨摩擦试验机,分析了摩擦力的变化规律及信号采集特点;介绍了一种摩擦系数的测试方法,针对si3N4/铸铁副的实验结果表明本试验机性能稳定可靠。

A kind of friction tester adopting of changing-di-rection tapping was developed, which can better simulate the practical lapping process;The characteristics of friction force and its signal-collecting is analyzed and a new technique for measuring friction-coefficient is introduced in this paper. The experiment for Sis N4/cast iron pair shows that this tester is stable in performance and can give reliable results.
