<p><P>PROBLEM TO BE SOLVED: To provide a vibrating cutting device of simple, compact and inexpensive structure capable of efficiently improving reliability and durability. <P>SOLUTION: This vibrating cutting device which rotates a cutting tool 8 fitted on a tip side while making the ultrasonic vibration in the axial direction, includes: a housing 4; a casing 2 supported by the housing 4 through a support mechanism 3; a motor housed in the casing 2; a spindle 63, which is driven to rotate by the motor and to which a cutting tool is to be fitted in the tip thereof; and a vibration generating portion 1 which vibrates the casing 2 in the axial direction. The support mechanism 3 has an operation converting part AL, which changes a rotational phase of the casing 2 by utilizing the vibrating operation of the casing 2 in the axial direction, so that the vibration converting part AL decomposes the vibration from the vibration generating portion 1 into the axial direction and the circumferential direction. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
