A processing tool of difficult-to-cut material for vibration reducing

摘要

The present invention is to reduce the occurrence of vibration on the vibration transmission path generated during the rotation and machining of the machining tool while enabling the machining of a difficult-to-cut material due to the high strength or physical properties of the material. It relates to a difficult-to-cut material processing tool for reducing vibration, wherein a fastening surface 11-1 stepped in the circumferential direction is formed on the central outer peripheral surface of the mounting body 11 of the machining tool, and the vibration mounted on the fastening surface 11-1 A reducing member 100 is installed, and the vibration reducing member 100 is divided into a first socket 210a on one side and a second socket 210b on the other side to form a mutually symmetrical shape, and the mounting body 11 The mounting hole 211 having a larger inner diameter than the outer diameter of the fastening surface 11-1 is opened on both sides while forming therein, and the step is interrupted by the step 11-2 at both ends of the fastening face 11-1. A socket unit 200 having a structure in which a locking tab 215 is formed to protrude in an arc shape at the inner peripheral end of the mounting hole 211 of the first and second sockets 210a and 210b facing (11-2); It is bound to the inside of the socket part 200 and is located between the first and second sockets 210a and 210b facing each other, and both side surfaces corresponding to the outer peripheral ends of the first and second sockets 210a and 210b respectively. The first and second sockets 210a and 210b of the vertical disk-shaped support part 310 and the center of both sides of the support part 310, respectively, extending to a predetermined horizontal length symmetrically with each other so as to be in close contact with the corresponding positions. It has a buffer part 320 to be inserted, respectively, and horizontally penetrates from the center of the exposed one surface of the one buffer part 320 to the center of the other exposed surface of the other buffer part 320 with respect to the support part 310 . The socket part 200 by binding the support part 310 of the vibration absorbing part 300 while passing through the vibration absorbing part 300 in which is formed, and the first and second sockets 210a and 210b of the socket part 200 . ) and a fastening means 400 for fastening and fixing the vibration absorbing part 300 to each other.
