在机械加工行业中，由于高速磨削可以大大提高工作效率，致使砂轮的发展也趋于高速化，而高速砂轮的出厂又必需经过回转试验机的强度检验，这就要求其转速越来越高，性能越来越好。一台优良的高速回转试验机应具有什么样的特性呢？我们根据工艺要求分析如下：（1）由于砂轮规格
In the machining industry, due to high-speed grinding can greatly improve work efficiency, resulting in the development of the wheel tends to speed, and high-speed wheel factory must go through the strength of the rotary testing machine, which requires higher and higher speed Performance is getting better. An excellent high-speed rotary testing machine should have what kind of characteristics? According to the technical requirements of our analysis are as follows: (1) due to wheel specifications
