Title: Vibration-cut drilling machine for precise boring of ceramics
Inventor: KUMABE JUNICHIRO
IPC: B23B37/00
Filed: 1987-10-23
Abstract: PURPOSE:To preform precise boring of ceramics in the same sense as working on metal by boring on cutting machining length to pieces with giving rotary motion to a tool, supersonic vibration to the tool and a work and superimposing still lower frequency vibration thereon. CONSTITUTION:A ceramics work 22 is made to vibrate in supersonic in an arrow mark 26 direction by a supersonic wave generator 27 via a longitudinal electrostrictive vibrator 28, a vibration main shaft 3 is made to rotate to an arrow mark 20 direction and a core drill 1 is made to vibrate in supersonic in an arrow mark 11 direction by a supersonic wave generator 19 via an electrostrictive vibrator 2. Precise bore working can be performed through making the core drill 1 vibrate in low frequency in an arrow mark 18 direction and giving feed (s) to an arrow mark 29 direction with changing over pressure oil from a hydraulic pressure device 4 by a control unit 17 on using a servo valve 15, on using an electro-hydraulic vibrating equipment 16. Again, the machine is used for finish working by changing a longitudinal vibrator 2 to a torsional vibrator and making the core drill 1 act in torsional vibration as against rough machining through longitudinal vibration. Still more, in a case of performing superprecise working with less cutting feed, finish working is performed with supersonic vibration alone after stopping low frequency vibration.
