我厂某产品零件,淬火后要切掉尾端达到成品尺寸并倒角。由于零件尾端细、长,硬度较高(材料为50B,淬硬HRC45～50),用一般车刀纵向走刀切削,不易加工,且刀具损坏严重。为此,采用淬硬钢强力切断倒角车刀,横向进给一刀切成,效果较好。刀具结构及几何参数如图2所示。 I plant a product parts, after quenching to cut off the end to the finished size and chamfer. As the tail part of the fine, long, high hardness (material 50B, hardened HRC45 ~ 50), with a general turning vertical cutting tool, not easy to process, and serious damage to the tool. To this end, the use of hardened steel strong cut chamfer turning knife, horizontal feed knife cut, the effect is better. Tool structure and geometry parameters shown in Figure 2.
