Document Type and Number:
WIPO Patent Application WO/2009/028120
Kind Code:
A1
Abstract:
[PROBLEMS] To perform position correction of a tool fixed to a tool holder with
high precision of micron order in the radial direction of the tool holder through
simple constitution and control. [MEANS FOR SOLVING PROBLEMS] The working machine
includes a tool holder (20) rotatable integrally with a spindle (16), a resilient
holder portion (24) of a ring shape having one end bonded to the tool holder (20)
and the other end for fixing blade tools (22a, 22b), a working shaft member (26)
having an end projecting axially outward of the resilient holder portion (24)
and rotatable relatively to the tool holder (20), a conversion mechanism (28)
for changing the rotary operation of the working shaft member (26) into radial
enlarging/shrinking operation of the resilient holder portion (24), and a support
mechanism (72) arranged on the outside of the tool holder (20) and coupled with
the working shaft member (26) in order to rotate it relatively to the tool holder
(20).
