Title:
ULTRASONIC MACHINING SPINDLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/004515
Kind Code:
A1
Abstract:
It is possible to stably supply an electric signal to an ultrasonic generation
element without causing friction or damage on parts or without requiring periodical
parts exchange. A reception coil (11) connected to a vibrator (6) is wound on the
outer circumference of a housing (1) constituting a shaft (30) of a machining
spindle (101). The reception coil (11) is surrounded coaxially by a transmission
coil (12) at an appropriate interval. A predetermined electric signal outputted
from an ultrasonic drive device (21) for driving the vibrator (6) is applied to
the transmission coil (12). The predetermined electric signal may be applied
to the vibrator (6) via the reception coil (11) by electromagnetic induction
between the transmission coil (12) and the reception coil (11).
