加工细长轴类一般采用高速切削用跟刀架支承,卡爪与工件表面接触过松或过紧,都会影响加工质量。尤其在加工圆锥细长轴类(如拉刀)一般跟刀架显得不适用,所以我们改装了自动补偿跟刀架。可以较合适址保持卡爪与工件表面接触。三爪的补偿是通过松紧圈的位移得到的,配重要选择合适,一般为2～4公斤。该刀架紧固在大拖板上找正后即可使用,使用时先按下件8,再放配重,切削时加冷却液,防止热伸的强 Slender shaft processing general use of high-speed cutting with a knife holder support, jaw and workpiece surface contact is too loose or too tight, will affect the processing quality. Especially in the processing of tapered slender shaft (such as broach) generally does not apply with the turret, so we modified the automatic compensation with the turret. Can be more appropriate to keep the jaw claws and workpiece surface contact. Three claw compensation is obtained by the displacement of the elastic ring, with the weight to choose the right, usually 2 to 4 kg. The knife holder fastened to the large carriage can be used to find positive, use the first press the next piece 8, and then re-equipped with heavy, cutting coolant, to prevent the heat of the strong
