Abstract
A roller milling tool unit is compact enough for insertion into a tool magazine of a machine tool and constructed to operate by a fluid circulating circuit of the machine tool. The unit has a tool section including a milling roller element and a fluid pressurizing section for generating the required hydraulic roller milling pressure. Both sections form a structural unit. The pressurizing section includes a pump connected to the fluid circulating circuit such as the cooling or lubricating circuit of the machine tool when the unit is in a working position on the tool carrier of the machine tool. The pump may be driven either by a hydraulic motor forming part of the tool unit or by a drive available in the machine tool. The hydraulic motor may be driven by the cooling or lubricating circulating circuit of the machine tool.
