Abstract
A facing head as well as a method for inserting a tool into and/or removing a tool from a tool holder device of the facing head. The facing head has a spindle coupling device for exchangeably coupling with a spindle chuck of a working spindle of a machine tool. The facing head has a housing body at which or in which a facing slide is moveably supported in a guided manner. The facing slide supports the tool holder device. The tool holder device is hydraulically controllable. A hydraulic coupling that is mechanically and hydraulically coupled with an associated hydraulic control coupling of the housing body in a tool change position of the facing slide. Remote from the tool change position, the mechanical and hydraulic connection between the hydraulic coupling and the associated hydraulic control coupling is interrupted. In the tool change position a switching of the tool holder device between a hold condition holding the tool and a release condition releasing the tool can be carried out by a respective pressurization with hydraulic pressure.
