加工条件:工件是12型电动脱粒机绞龙主轴:材料45钢,尺寸φ20×850、▽ 6、主轴中段焊有螺旋叶片,影响平衡,且不便落扶架。加工部位为轴头尾各一段。在 C6140车床上进行车削。原来工艺:转速 n=485转/分,走刀量 S=0.2毫米/转,刀具主偏角φ=90°,每班只能加工7—8条,且振动大,表面光洁度达不到▽6,需用锉刀手工修整。 Processing conditions: The workpiece is 12-type electric thresher Drilling spindle: 45 steel material, size φ20 × 850, ▽ 6, the middle of the spindle welding spiral blades affect the balance, and not easy to fall on the shelf. Processing parts for the shaft head tail of a paragraph. Turning on the C6140 lathe. The original process: speed n = 485 rev / min, take the amount of S = 0.2 mm / rev, the main tool angle φ = 90 °, processing only 7-8, and the vibration, the surface finish up less than ▽ 6, the need to manually trim file.
