这种铰刀(见图)主要特点是无切削刃,完全靠挤压力作用进行加工,表面光洁度良好,金属表面致密,机械强度可以提高,耐磨性增强,延长了刀具使用寿命。刀具刃磨:一般可用工具磨床刃磨,也可用手工刃磨;刀片牌号:YG 6;刀杆材料:45钢; 工件材料:铜、铝;使用机床:C 620或 C 616车床;切削用量:v=20～30米/分;s=0.075～0.11毫米/转;毫米(直径方向)t=0.03～0.06。铰孔后表面光洁度可稳定在▽8～▽9,精度可达2级,寿命可延长一倍
The main features of this reamer (see photo) are: no cutting edge, completely pressed by the role of processing, surface finish, dense metal surface, mechanical strength can be increased, increased wear resistance, extending tool life. Tool sharpening: General tool sharpening grinding tools, also available manual sharpening; Blade grades: YG 6; Arbor material: 45 steel; Workpiece material: copper, aluminum; Use machine: C 620 or C 616 lathe; Cutting dosage: v = 20-30 m / min; s = 0.075-0.11 mm / rev; millimeter (diameter direction) t = 0.03-0.06. Reaming surface finish can be stabilized at ▽ 8 ~ ▽ 9, the accuracy of up to 2, double the life expectancy
