Title: Turning tool
Inventor: HAGA KATSUMI
IPC: B23B27/00
Filed: 1992-07-16
Abstract: PURPOSE:To machine a deep hole, and to extend the lifetime of a tip by preventing chattering vibration of a turning tool, especially, that of a boring bar from occurring at the time of cutting. CONSTITUTION:A turning tool is made up of a weight 12 housed within a hollow part formed in its holder body 10 and a resiliently deformable linear support means for supporting the weight 12, and the length or the diameter of the support means is changed by affording tension thereto. A diaphragm 32 which is displaced due to fluid pressure or a means which mechanically moves is disposed as the means for affording tension to the support means. The change of at least either one of the length and the diameter of the support means resulting from the affording of tension thereto changes the natural frequency of the weight, and chatter is suppressed by setting this natural frequency to an appropriate value. This enables a tip to be protected, a deep hole to be machined, and a machining surface roughness to be improved and working noise to be reduced.
