我们采用对刀来加工切根内螺纹(图1),对刀如图2所示。这种对刀一头是内圆刀,一头是内螺纹刀。装夹该刀时,要求内圆刀的内端面主切削刃α与内螺纹刀尖相距s/2的距离(s为螺距)。装刀时应使AA与车床主轴轴线成垂直。操作时,内孔深度用靠山定位。当加工完内孔后。内螺纹刀就在靠山的位置开始切削,开倒车,从里向外车削螺纹。第二刀、第三刀都在靠山的位置进刀。这样加工,要比用普
We use the knife to process the root cutting thread (Figure 1), the knife shown in Figure 2. This knife is a knife inside the knife, one is a female thread knife. Clamping the tool requires that the inner cutting edge of the inner circular cutter be at a distance s / 2 from the tip of the female thread (s is the pitch). When installing a knife, make the AA perpendicular to the lathe spindle axis. Operation, the depth of the hole with the positioning of the back. After machining the inner hole Internal thread knife in the back of the site began cutting, open reverse, turning from the inside out thread. The second knife, the third knife are in the position of the knife. This processing, than the general use
