我厂加工的铝合金电信轮,其内孔Φ10H8,R_a0.8,径深比为1/15,采用普通铰刀很难达到要求。为此,我们改制了一种铰刀,使用效果良好。现介绍如下: 1.刀具特点 (1)刀具采用标准Φ10mm×150mm六刃高速钢铰刀改制。用砂轮割断原有柄部,利用Φ5mm低碳 I plant processed aluminum telecom wheel, the hole Φ10H8, R_a0.8, depth-depth ratio of 1/15, the use of ordinary reamer is difficult to meet the requirements. To this end, we reorganized a reamer, the use of good results. Are introduced as follows: 1. Tool Features (1) the use of standard tool Φ10mm × 150mm six-blade high-speed steel reamer restructuring. Cut the original handle with a grinding wheel, using Φ5mm low carbon
