Abstract
Tool holding systems described herein include a tool holder configured to releasably retain a metal-processing tool and to define a tool holder passage extending along a stroke axis, an adjustment drive operable to rotate the tool holder about the stroke axis, and a stroke drive including a spindle operable independent of the adjustment drive to translate the tool holder along the stroke axis. The stroke drive defines a stroke drive passage cooperating with the tool holder passage to define a waste disposal passageway through the tool holding system.
Claims9
A method of machining a workpiece, the method comprising:
- retaining a metal-processing tool on a tool holder;
- rotating the position of the tool holder about a stroke axis with an adjustment drive;
- translating the position of the tool holder along the stroke axis with a stroke drive having a spindle operable independent of the adjustment drive and extending with an axis along the stroke axis;
- maintaining an access passage through the tool holder and the stroke drive while adjusting the position of the tool holder, wherein the access passage through the tool holder and the stroke drive is maintained by the tool holder having an orifice and by the stroke drive having a spindle in the form of a hollow spindle, wherein the hollow spindle comprises an inner recess aligned with the orifice of the tool holder and the hollow spindle further comprises an outer flange at which the hollow spindle is rigidly coupled to a rotor of an electric drive motor of the stroke drive, and wherein the rotor of the electric drive motor and the hollow spindle jointly revolve about the stroke axis;
- and
- processing the workpiece with the metal-processing tool.
