Abstract: A machining device has a tool spindle for machining workpieces which is connected to a first provision unit for providing a cooling fluid and to a second provision unit for providing a fluid or a lubricant-fluid mixture. The provision units are controlled by means of a control unit. Control is performed by in particular at least one measuring sensor, for instance a thermometer, by means of which a flow rate of the cooling fluid and/or the fluid or the lubricant-fluid mixture is adjusted. The tool spindle is provided with two supply channels for supplying the cooling fluid and/or the fluid or the lubricant-fluid mixture. The supply channels allow the cooling fluid and/or the fluid or the lubricant-fluid mixture to be supplied to the machining tool. This results in an optimized machining process for the most different cutting processes and materials of the workpiece.

Abstract: A machine tool for the production of teeth on workpieces is provided, comprising a workpiece holding device, a cold rolling device for the production of rough teeth on at least one workpiece held by the workpiece holding device by way of cold rolling and a cutting machining device for the fine cutting machining of the rough teeth of the at least one workpiece which is held on the workpiece holding device.
