由于有色金属材料材质较软,韧性较大又不能磨削,因此在加工时不易提高其表面光洁度。例如:紫铜T1～T4,铝L1～L4以及它们的合金,我们在铣削时将铣刀前角磨成25°～30°,为防止使用硬质合金端铣刀磨出较大前角后容易脆裂的缺陷,所以我们制成了机夹高速钢端铣刀(图1),来精铣表面光洁度要求高的有色金属零件。刀头用8×8毫米的 As the non-ferrous metal materials softer, more tough and can not be ground, so processing is not easy to improve its surface finish. For example: copper T1 ~ T4, aluminum L1 ~ L4 and their alloys, we grind the milling cutter front angle to 25 ° ~ 30 °, in order to prevent the use of carbide end mill after grinding a large rake easier Therefore, we made a high speed steel end mills (Figure 1), to finish milling non-ferrous metal parts with high surface finish.
