Abstract
In order to process a solid processed object with a simple construction, and to process a solid and flat work while effectively collecting particulate scraps, in a machine tool for processing work in which a working table on which the work is mounted and a spindle in which a cutter is installed move relatively to each other, a bellow which telescopes freely is provided, one open end of which connects to the spindle head so as to surround the spindle, and the other open end of which connects to a working table in such a manner as to surround the work.
Claims18
A machine tool comprising:
- an enclosing means constructed on a working table having an open upper surface, and enclosing a processed object;
- a processing means for processing the processed object;
- a moving means on which said processing means is installed disposed over said enclosing means, the moving means moves over the open upper surface of the enclosing means following a change of relative position between the processing means and the working table in a horizontal plane;
- a connecting means which is interposed between the processing means and the moving means, the connecting means expanding and contracting in a vertical direction according to a vertical motion of the processing means;
- a covering means which is disposed between the enclosing means and the moving means so as to cover the upper open end of the enclosing means, the covering means expands and contracts to follow motion of the moving means;
- and
- wherein the moving means comprises a first moving table that moves on first guide rails and a second moving table that moves on second guide rails, said second guide rails being disposed perpendicular to said first guide rails.
