Abstract
The present invention concerns a bore head, which consists essentially of a body () provided with a radial piston () for receiving a bore tool () which can be tightened in said radial piston () with a tightening means (), where the position of said radial piston () can be regulated by means of a micrometric screw (), and where the radial piston is guided and tightened in the regulation position with a guidance and tightening means, and where, moreover, said body is provided with a balancing device () with balancing weights (and). Bore head characterized in that the means () for tightening the bore tool () in the radial piston () of the body () is in the form of a screwing device (), equipped with a movable center punch () which is under tension caused by a spring (), and in that the means for guidance and tightening in the position of regulation of the radial piston () is an indirect tightening means which carries out said guidance and tightening radially. The invention can be applied more particularly in the field of accessories for machine tools, with digital control, for machining centers, cells and workshops for multiple purposes.
