METHOD AND APPARATUS FOR MACHINING JOINT FACE OF WORK
Document Type and Number:
WIPO Patent Application WO/2002/070196
Kind Code:
A1
Abstract:
A method and an apparatus for machining the joint face of a work in which a joint face exhibiting high airtightness is provided by eliminating leakage due to streaks caused by abrasive grains. At the time of machining the joint face (15) of a work (31), a grinder (11) rotating about rotational axes (33, 35) substantially parallel with the joint face (15) is pressed against the joint face (15) of the work (31) and fed relatively between the grinder (11) and the work (31) in the direction substantially copying the contour of the joint face (15) while controlling the orientation of the grinder (11) or the work (31) such that the rotational axes (33, 35) of the grinder (11) is substantially orthogonal to the relative feeding direction thus grinding the joint face (15) of the work (31).
