在兄弟单位经验的启发和我市文化宫刀具学习班及市金切交流队工人师傅的帮助下,结合我厂加工情况,最近我们制造并采用了两种强力切削刨刀(图1、图2)。实践证明,这种刨刀效果很好。 1.刀具材料:加工灰铸铁时:刀片为YG8;加工45钢时:刀片为YT5或W18Cr4V。 2.刀具的特点: (1)有25°刃倾角,因此具有较高的耐冲击性能; (2)前角很大(35°),并且在前面上还磨有R125的圆弧,可使切屑形成片状顺利 Inspired by the experience of our brother units and the help of the craftsmen of the Culture Palace Cutlery Workshop and the city Jinchao Exchange Team, combined with the processing of our factory, we recently manufactured and adopted two kinds of powerful cutting planing knives (Figure 1 and Figure 2). Practice has proved that this planing knife works well. 1. Tool material: gray iron processing: blade YG8; processing 45 steel: the blade is YT5 or W18Cr4V. 2. Tool Features: (1) Inclination of 25 °, resulting in higher impact resistance; (2) Large rake angle (35 °) and rounded R125 on the front, The chips form a smooth sheet
