Abstract:
A scrap removing and tool cooling device adapted to blow cooling air to the vicinity of a front holding end of a tool spindle of a machine tool, the machine tool having a housing that includes a front end wall disposed for passage of the front holding end of the tool spindle and a surrounding wall extending rearwardly from a periphery of the front end wall to surround the tool spindle, the tool spindle extending in an axial direction and having the front holding end thereof protruding outwardly of the front end wall for holding a tool insert, said device comprising:a cooling air conduit adapted to be disposed in the housing and extending in the axial direction, said cooling air conduit including an inlet adapted to be formed in the surrounding wall of the housing for introducing cooling air therein, and an outlet adapted to pass through the front end wall of the housing; anda hood member including a rear surrounding wall adapted to engage the front end wall of the housing and to extend so as to surround and be spaced apart from the front holding end with a first distance in a direction radial to the axial direction, thereby cooperating with the front end wall to define a chamber to communicate with said outlet, and a front surrounding wall extending forwardly from said rear surrounding wall and adapted to surround and be spaced apart from the front holding end with a second distance in the radial direction and smaller than the first distance, thereby cooperating with the front holding end to define a blowing outlet to communicate with said chamber.
