Patent ID: 7926155

Claim:
Machine tool comprising a machine frame, a first workpiece carrier unit, which is disposed on the machine frame and has a workpiece receiving means, at least one tool carrier unit, which is disposed on the machine frame, the at least one tool carrier unit having a tool carrier base and a tool carrier head, which is movable in relation to the tool carrier base along an axis of advance by means of a guiding arm and is rotatable about an axis of rotation parallel to, or coincident with, the axis of advance by means of the guiding arm, the tool carrier head is formed as a multiple tool carrier and comprises a tool spindle which is provided with a spindle motor with a spindle shaft and a rotatably driveable tool for machining a workpiece held in the workpiece receiving means, said rotatably driveable tool is seated in said spindle shaft, the tool carrier head has at least two tool planes, such that, in each tool plane, at least one tool extends with a longitudinal direction thereof in at least one respective tool direction along the respective tool plane, the at least two tool planes run parallel to, or coincident with, the axis of rotation, the at least two tool planes of the tool carrier head run through a common straight line, the common straight line lies within a geometric cylindrical space around the axis of rotation, which has a maximum radius corresponding to no more than an average radius of the guiding arm, and a working space, in which a workpiece held in the workpiece receiving means can be machined with the at least one rotatably driveable tool, and the tool carrier head is fixedly connected to the guiding arm.
