This programme structure is simple, processing ease, and the trace that can realize in boring cutter process floats, thus realizes the hole that boring cutter boring when bore hole goes out dimensional accuracy height and any surface finish, improves the crudy in hole.
Further, also comprise adapter sleeve, adapter sleeve is connected by pin with machine tool chief axis, and adapter sleeve and caudal peduncle upper end are by being connected, and be provided with external screw thread outside caudal peduncle, adapter sleeve lower end is provided with the internal thread mated with external screw thread outside caudal peduncle.
Further, also comprise cushion block, cushion block, between groove top and steel ball, can make steel ball push against joint dop by cushion block, thus makes caudal peduncle transfer torque to joint by the dop friction of groove and joint.
Further, the screw thread on nut is Tang thread, when making nut push against nut cap, has good anti-loosing effect.
Further, adapter sleeve sidewall is provided with screwed hole, caudal peduncle is provided with draw-in groove with screwed hole corresponding position, connects lock-screw in screwed hole, and lock-screw extend in draw-in groove and can prevent caudal peduncle and adapter sleeve from relatively rotating.
