Abstract
A machine tool for machining a blank, such as round bar, comprising an electric motor which includes a motor housing having an axial bore through which the blank can extend, an annular stator arranged in said motor housing, and an annular rotor arranged in and coaxially to the annular stator, a chucking device for clamping the blank which extends through the axial bore and the annular rotor, and at least one cutting tool for machining the blank, one of the chucking device and the cutting tool being mechanically and immovably connected to the motor housing and the other being mechanically and rotatably connected to the annular rotor.
Claims9
A machine tool for machining a blank, such as a solid or hollow round bar, comprising an electric motor which includes a motor housing having an axial bore through which said blank can extend, an annular stator arranged in said motor housing, and an annular rotor arranged in and coaxially to said annular stator, a chucking device for clamping said blank which extends through said axial bore and said annular rotor, and at least one cutting tool for machining the blank, one of said chucking device and said at least one cutting tool being mechanically immovably connected to said motor housing and the other being mechanically and rotatably connected to said annular rotor;
- and a hollow outer cylinder which is coaxially connected to said annular rotor so as to rotate together therewith and a hollow inner cylinder which is immovably connected to said motor housing and which is arranged in and coaxially to said outer cylinder, said chucking device being connected to said inner cylinder, said at least one cutting tool being mechanically connected to said rotatable outer cylinder so as to rotate together therewith.
