Document Type and Number:
WIPO Patent Application WO/2019/240268
Kind Code:
A1
Abstract:
[Problem] To provide an ultrasonic cutting device with which ultrasonic energy produced by applying electric energy to a piezoelectric element attached to a disc-shaped cutting tool is propagated at high efficiency to a blade edge of the cutting tool. [Solution] An ultrasonic cutting device includes: a disc-shaped cutting tool that is mounted onto a spindle and provided with annular flanges attached so as to protrude out in the vertical direction from both a front-side surface and a reverse-side surface, and provided with an annular piezoelectric element attached so as to be concentric with the flanges; and a support body structured to contact distal end parts of the flanges and to support the disc-shaped cutting tool with pressure directed toward the two surfaces of the disc-shaped cutting tool.
