金属切削加工中产生的高温不仅会影响金属去除率,而且会缩短刀具的使用寿命。美、日等国发展了一种称之“静电冷却”的冷却刀具方法,据说在刀具上通以静电后,可以显著降低切削刃的温度。 静电冷却的简单机理是,通过一种比较安全的高电压、低电流的静电触头将电子流引向冷却区,而利用电子流的摩擦效应去除边界绝 The high temperature generated in metal cutting affects not only the metal removal rate but also the tool life. The United States, Japan and other countries have developed a so-called “electrostatic cooling” cooling tool method, said to pass on the tool with static electricity, you can significantly reduce the cutting edge temperature. The simple mechanism of electrostatic cooling is to direct the electron flow to the cooling zone through a relatively safe, high-voltage, low-current electrostatic contact while removing the boundary by the frictional effect of the electron flow
