MACHINE TOOL WITH TWO TOOL SPINDLE HEADS AND COVER APPARATUS THEREFOR

摘要

Pair of columns 3 and 4 are provided on a bed so as to be movable in a approach and separate direction to each other. On inside surfaces facing with the columns 3 and 4 to each other, there are respectively arranged tool spindles 32 and 32' which are movably guided in one of first and second directions mutually perpendicular to a first direction that is a moving direction of the columns 3 and 4. Each of the tool spindles 32 and 32' performs machining operations with respect to a common worktable by independently moving in the three directions mutually perpendicular to each other. Upper-lower covers 50 are intentionally arranged in a front of each of the columns 3 and 4 by upper and lower winders 52 and 53 so as to cover the front of each of the columns 3 and 4. Further, a cover apparatus 60 is intentionally arranged between the columns 3 and 4.
