1.钛合金及刀具特点钛合金是一种比较难加工的特种材料。因为它具有耐高温、强度高、比重小耐腐蚀等特点。同时,在切削过程中易与空气中的氧、氢、氮等元素形成硬脆的化合物,所以加工困难。又由于当切屑经主切削刃切离后,则切屑立即向上卷起,与刀具前面的接触面积很小(大约为钢材的三分之一),所以,在同样的切削用量情况下,加工钛合金时,刀具单位面积所承受的压力要比加工一般钢材大得多,这也是造成难加工的一个不利因素,因此加速刀
1. Titanium and tool characteristics Titanium alloy is a more difficult to process special materials. Because of its high temperature, high strength, small proportion of corrosion-resistant and so on. At the same time, easy to form hard and brittle compounds with the oxygen, hydrogen, nitrogen and other elements in the air during the cutting process, so the processing is difficult. And because when the chips cut off by the main cutting edge, the chip rolled up immediately, and the contact area with the front of the tool is very small (about one-third of the steel), so the same cutting conditions, the processing of titanium Alloy, the tool per unit area under pressure than the general processing of steel is much larger, which is difficult to create a negative factor, so accelerate the knife
