It floats.
This programme structure is simple, and operation is easy, and the micro floating in boring cutter process may be implemented, to realize boring cutter
In bore hole, boring goes out the hole of dimensional accuracy height and any surface finish, improves the processing quality in hole.
It further, further include connector sleeve, connector sleeve and machine tool chief axis by pin connection, connector sleeve passes through company with caudal peduncle upper end
It connects, external screw thread is equipped on the outside of caudal peduncle, connector sleeve lower end is equipped with and the matched internal screw thread of external screw thread on the outside of caudal peduncle.
It further, further include cushion block, cushion block can be such that steel ball abutting connects between groove top and steel ball, through cushion block
Head clamp, so that caudal peduncle be made to transfer torque to connector by the clamp friction of groove and connector.
Further, the screw thread on nut is Tang thread, when nut being made to push against nut cap, has good anti-loosing effect.
Further, connector sleeve side wall is equipped with threaded hole, is equipped with card slot with threaded hole corresponding position on caudal peduncle, connects in threaded hole
Lock-screw, lock-screw, which is extend into card slot, can prevent caudal peduncle and connector sleeve from relatively rotating.
