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.

A tool holding system comprising:
- a tool holder configured to releasably retain a metal-processing tool and defining 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 comprising a spindle operable independent of the adjustment drive to translate the tool holder along the stroke axis,
- wherein 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.
A machine tool for processing a workpiece positioned in a working area, the machine tool comprising:
- a tool holder to support a punch tool and defining an opening proximate the working area of the machine tool, the tool holder configured to rotate about a stroke axis;
- and
- a tool stroke drive comprising a spindle gear that comprises a spindle-spindle nut unit;
- wherein the spindle-spindle nut unit comprises a spindle and a spindle nut operably connected with each other and the spindle nut is attached to the tool holder,
- wherein the tool stroke drive is configured to move the spindle nut and the tool holder along the stroke axis, and;
- wherein the tool holder and the tool stroke drive holder define a continuous central bore.
