MACHINE TOOL WITH WORK SPINDLE AND MATERIAL MACHINING METHOD BY THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/089987
Kind Code:
A1
Abstract:
A machine tool (10), comprising a work spindle (12) capable of holding and rotating a work material (W), a tool mounting part (16) fitted to the work spindle so as to be operated together with the work spindle and to which a tool (14) is fitted, an operating mechanism (18) operating the work spindle, and a rotatable second work spindle (24) formed separately from the work spindle (12). The tool mounting part (16) further comprises a plurality of tool holding parts (22) disposed on the work spindle about the rotating axis (12a) thereof at specified intervals in the circumferential direction. The control device (20) of the operating mechanism (18) indexes and rotates the work spindle so that the plurality of tools fitted to the plurality of tool holding parts can be selectively positioned at their respective work positions (P). Also the control device (20) can make the tool fitted to the tool mounting part operate to cut a work material (W’) held on the second work spindle.
