LATHE PROVIDED WITH ULTRASONIC MACHINING TOOL

PROBLEM TO BE SOLVED: To provide a turret type NC lathe provided with an ultrasonic machining tool with a simple facility requiring no exclusive cable restricting no action space of a turret, and a lathe having a comb type cutter base provided with an ultrasonic machining tool with a simple facility requiring no exclusive cable restricting an action space of the comb type cutter base. SOLUTION: In the turret lathe, a primary coil is arranged at a fixed part 11 and a secondary coil is arranged at a center of the turret 12 in opposed thereto. In the lathe having the comb type cutter base, a plurality of ultrasonic machining tools 17a-17e are arranged at the comb type cutter base and the secondary coils are connected to the respective ultrasonic machining tools respectively. The primary coil and a high frequency power source are arranged at the fixed part 11 in opposed to the secondary coil. Thereby, the high frequency power source and an ultrasonic vibrator are not brought into contact and a high frequency signal is fed to the ultrasonic vibrator. COPYRIGHT: (C)2004,JPO&NCIPI
