钛合金的应用已逐渐广泛,但对钛合金的铣削加工是比较困难的。其主要原因是:毛坯表面层的硬度很高;导热性差,切削热不能很快传出,大部分热量积聚在切削刃和刀片表面;钛合金在切削温度下,同刀具的亲合力强,这将造成刀具的熔接和粘结磨损,加速刀具的损坏;弹性模数小,切削时容易引起让刀和振动,采用强力切削,方可避免。为了适应钛合金的加工
The application of titanium has been gradually widespread, but the milling of titanium alloys is more difficult. The main reason is: rough rough surface layer hardness; poor thermal conductivity, cutting heat can not be quickly transmitted, most of the heat accumulation in the cutting edge and the blade surface; titanium alloy cutting temperature, with the tool affinity, which Will cause the tool welding and bonding wear and tear, accelerated tool damage; elastic modulus is small, easy to cause when cutting knife and vibration, the use of cutting force before they can be avoided. In order to adapt to the processing of titanium
