Abstract
In a vibration cutting unit, a root portion of a holding member for supporting a vibration body is fixed on a fixed portion of a node portion which is common to axial vibration and bending vibration, on a jointless basis. Therefore, the node portion, namely, a vibration body main part is firmly fixed, thereby, the vibration body main part is supported stably, and vibrations of the vibration body main part is stabilized. In other words, vibrations under the mode where the vibration body main part cannot be controlled can be restrained, and works representing objects to be processed can be processed accurately.
Claims20
A vibration body for cutting, comprising:
- a vibration body main part which is capable of holding a cutting tool for vibration cutting and which transmits a vibration to the cutting tool when the vibration body main part holds the cutting tool, the vibration body main part having a node portion corresponding to a vibration node relating to at least bending vibration caused along a bending vibration plane while the vibration body main part vibrates;
- and
- a holding member which is integrally fixed to the node portion and extends in a normal line direction of the bending vibration plane for supporting the node portion.
