Vibrating cutting tool
First Claim
Patent Images
1. A vibration cutting tool, comprising:
- a cutter holder having a cutter mounting portion;
a cutter supported on said cutter mounting portion, with a gap remaining between said cutter and said cutter holder, wherein said cutter is vibratable microscopically when it engages a rotating workpiece and encounters a cutting resistance;
a spring means supported on said cutter holder so as to be resiliently deformable when an edge of said cutter vibrates, thereby urging said cutter; and
a ball disposed between said cutter and said spring means for transmitting vibrations between said cutter and said spring means;
wherein said gap reduces such that said cutter abuts said cutter holder when the cutting resistance exceeds a predetermined value.

Abstract
A vibrating cutting tool capable of making uniform micro-vibrations at the cutter edge generated during machining. The vibrations at the cutter edge are transmitted to balls biassed by springs, compressing the springs. The vibrations are transmitted from the balls through the output shaft back to the cutter edge. While the cutting force is small, the amplitude of vibration of balls is relatively large. When it increases, the holder acts on the balls more than the spring does so that vibration is suppressed. As a result, the amplitude of vibration becomes uniform.
