Abstract
A machine tool (1) removes chips adhering to a working portion of a tool (T). More specifically, a fluid injecting nozzle (23, 24) injects a fluid toward the tool (T) enclosed in an enclosure (22). A controller (15) controls a position of the tool (T) within the enclosure (22), and further controls operation of the fluid injecting nozzle (23, 24) such that the fluid is injected when the tool (T) is within the enclosure (22).
Claims3
A machine tool, comprising:
- a tool spindle as a tool holding unit holding a tool, the tool spindle being configured such that the tool can be attached;
- a turret formed in a polygonal prism shape, the turret having a plurality of instrument attachment surfaces on side surfaces thereof and having an end surface perpendicular to the plurality of instrument attachment surfaces;
- a feed mechanism moving the tool spindle in at least one axis direction;
- an enclosure attached to the turret so as to be positioned within a movement area of the tool, the enclosure having an opening and having an interior area into which a portion of the tool exposed outside from the tool spindle can be partially or entirely enclosed through the opening;
- a fluid injecting nozzle provided on at least one of the tool spindle and the enclosure and injecting a fluid toward the tool enclosed in the enclosure;
- and
- a controller controlling the feed mechanism such that the tool is enclosed into the enclosure by moving the tool spindle, and controlling an injecting operation of the fluid injecting nozzle such that the fluid is injected in a state where the tool is enclosed in the enclosure, wherein:
- the enclosure has a bottom on a side opposite to the opening;
- and
- the enclosure is attached at the bottom thereof to one of the plurality of instrument attachment surfaces of the turret or attached at an outer surface thereof to the end surface of the turret.
