加工铝所需的切削力要比加工其它金属材料小得多,由于这个原因,加工时可选择较高的切削速度和较大的前角。在自动车床上加工时,应采用添加铅的特殊铝合金。
The cutting force required to machine aluminum is much smaller than machining other metal materials. For this reason, higher cutting speeds and larger rake angles are available for machining. In the automatic lathe processing, should be used to add special aluminum alloy lead.
