在镗床加工孔的过程中,往往会碰到孔口倒大于3×45°的角。如果用成形刀进行靠刀加工,这时的切削宽度越来越大,切削力也随之加大,这样会引起主轴的振动。影响零件表面光洁度,对主轴本身及加工零件是不利的,尤其是薄壁零件。如果采用两个矢量合成的原理,利用主轴的走刀与刮面镗头走刀结合起来,便能很容易地解决上述问题(图1)。 Boring hole in the process of drilling, often encounter the hole down more than 3 × 45 ° angle. If the forming knife by knife processing, then the cutting width is bigger and bigger, the cutting force will also increase, this will cause the spindle vibration. Affect the surface finish of parts, the spindle itself and the processing of parts is negative, especially thin-walled parts. If we use the principle of two vector synthesis, the use of the spindle of the knife and the boring head boring knife together, you can easily solve the problem (Figure 1).
