铝合金是一种很轻的有色金属,它的性质比较软,所以它的机械加工性不大好。由于这个缘故,我们在加工铝合金时,常常会发现有“粘刀”现象。现在我们就来谈谈什么是“粘刀”现象,它对工作的影响和产生“粘刀”的原因,以及避免的方法。此外,还谈一谈车削铝合金时,刀具几何形状的正确选择,和润滑冷却液的选用。 Aluminum alloy is a very light non-ferrous metal, its nature is relatively soft, so its machinability is not good. For this reason, we often find “stick knife” when processing aluminum alloy. Now let us talk about what is the “stick knife” phenomenon, its impact on the work and the resulting “stick knife” reasons, as well as ways to avoid. In addition, talk about turning the aluminum alloy, the correct choice of tool geometry, and the choice of lubricating coolant.
