ABSTRACT:
A device to hold workpieces, in particular gears, to hone an existing axial center bore, consisting of a workpiece support member, which may be loaded and unloaded from one side. Levers supported pivotably in grooves formed in the workpiece support member are provided with tooth-like ends which engage tooth gaps of the workpiece in an approximately diametrically opposed manner. The levers are resiliently biased to rest in their engaged position in the direction of rotation of machining against stop surfaces of the grooves, with the levers being pivoted in the opposite direction during unloading to disengage the lever ends from the workpiece.
