LONG SHAFT BIT HAVING VIBRATION PREVENTING STRUCTURE
First Claim
Patent Images
1. A long shaft bit with a vibration suppressing structure, comprising:
- a tip fixing part disposed at a front end of the long shaft bit and coupled to a cutting tip;
a shank which is connected to the tip fixing part; and
a bit fixing part which is connected to the shank, the bit fixing part for fixing the bit,the vibration suppressing structure being disposed on an outer surface of the shank and comprising a vibration absorbing body disposed on the outer surface of the shank in a multi-layer and a hollow wire rod spirally coiled in a second absorption layer, a third absorption layer, and an outermost layer of the vibration absorbing body,whereby the vibration suppressing structure absorbs vibration and prevents resonance during cutting process for a cutting subject.

Abstract
The present invention relates to a bit for processing the inside diameter of a work material, the bit having on the outer surface of a shank a vibration preventing structure comprising a vibration absorption body made of a silicone material, and a hollow wire rod, thereby absorbing the vibration generated from a machine tool, preventing resonance generated between the work material and a tool, and thus, enabling the implementation of a slickenside from ultra-precision machining.
