Abstract
A tool head having a first slide fitted with a tool holder as well as a second slide for eliminating the unbalance effect created by the off-centering of the first slide. An actuating device that can be actuated longitudinally that is able to control the radial displacement of the two slides. Each of these slides is provided with a pressing device for pressing the slide against an oblique support surface of the actuating device. The force exerted by each of the pressing devices is determined, so as to be greater than the centrifugal force exerted on each slide and in a direction opposed to that of the centrifugal force. This force is determined so that the resultant force of all forces exerted on each slide is constant.
Claims10
A tool head, comprising:
- a tool holder having a first slide able to be displaced both ways along a first direction perpendicular to an axis of rotation of the tool head,
- a second slide able to be displaced both ways along a second direction parallel to said first direction,
- a displacement control means for controlling the displacement of said first slide and said second slide and able to move said first slide and said second slide in an opposed direction from each other, said displacement control means being operated both ways of a direction parallel to the axis of rotation of the tool head,
- pressing means able to exert on said first slide and said second slide a force greater than a centrifugal force exerted on said first slide and said second slide and in a direction opposed to that of the centrifugal force, such that the resulting force exerted on said first slide and said second slide remains at a constant value, and
- a control unit, said pressing means being operated by the control unit.
