钛合金由于具有比重小、温度高、耐腐蚀性好、在500℃以下具有良好的热稳定性等特点,加之我国的钛资源十分丰富,故钛合金被广泛地应用于飞机、火箭、人造卫星、坦克、潜艇和精密仪器上。但是,由于钛合金某些特殊的物理、机械性能、致使钛合金很难进行磨削加工。钛合金的熔点高达1725℃,其导热系数仅为铝的1/4、钢的1/5,而钛合金的摩擦系数却很高,这样,在磨削过程中将产生大量磨削热,由于磨削热不能迅速传出磨削区,则必将引起磨削区温度过高,而使工件产生磨
Titanium alloy is widely used in aircraft, rockets, satellites due to its small specific gravity, high temperature, good corrosion resistance, good thermal stability below 500 ℃, and titanium resources in China. Tanks, submarines and precision instruments. However, due to the special physical and mechanical properties of titanium alloys, titanium alloys are difficult to grind. The melting point of titanium alloy up to 1725 ℃, the thermal conductivity of only 1/4 of aluminum, steel 1/5, while the high coefficient of friction of titanium alloy, so that grinding process will produce a lot of grinding heat, as a result of Grinding heat can not be quickly spread out of the grinding area, it will inevitably lead to grinding zone temperature is too high, leaving the workpiece grinding
