Wheelhead for grinding machines

Abstract

A wheelhead for use in grinding and like machines has a spindle which is rotatably mounted in a bearing and supports at least two grinding wheels one of which is attached to the spindle for treatment of two or more successive workpieces, particularly for finish grinding camshafts, cylinders, rolls and like objects. Another grinding wheel is separably coupled to the spindle so that it can be detached upon completed preliminary treatment of each of a series of successive workpieces. The separable grinding wheel is outwardly adjacent the one grinding wheel and is coupled to the spindle by manually operable means or by means which facilitates automatic mounting of such wheel on and automatic detachment of such wheel from the spindle by a wheel changer. The wheelhead can be used with advantage in universal or special external cylindrical grinding machines.
