Abstract
The present invention relates to a machine tool for machining a workpiece. The machine tool has a motor spindle for the rotative actuation of a tool. The motor spindle is supported by a stand. A turning bearing is provided at the stand and the motor spindle at the turning bearing is pivotable and positionable about a first turning axis. At the motor spindle, a linear guide is provided, which enables an advancing movement of the tool parallel to the spindle axis.
Claims15
A machine tool for machining a workpiece comprising:
- a motor spindle for the rotative actuation of a tool about a spindle axis, and the motor spindle is supported by a stand, wherein a turning bearing is provided at the stand, and the motor spindle at the turning bearing is pivotable and positionable about a first turning axis, and a linear guide is provided at the motor spindle, which enables an advancing linear movement of the tool parallel to the spindle axis, further comprising a spindle bed, pivotable and positionable about the first turning axis, provided at the turning bearing, and wherein the motor spindle is mounted via the linear guide in the direction of the spindle axis on or at the spindle bed, wherein the turning bearing is formed in a shape of a fork or a claw by two turning bearing supports spaced apart, and the motor spindle or the spindle bed is situated between the turning bearing supports, and the turning bearing has an arc-shaped clamping surface of the spindle bed at the clamping segment with aid of a clamping device.
A machine tool for machining a work tool comprising:
- a motor spindle for the rotative actuation of a tool about a spindle axis, wherein the motor spindle is supported by a stand, and wherein a turning bearing is provided at the stand, and the motor spindle is mounted on a spindle bed and is pivotable and positionable at the turning bearing about a first turning axis;
- and
- a linear guide at the motor spindle, which enables an advancing movement of the tool parallel to the spindle axis, wherein the spindle bed is configured in a shape of a cage or a tunnel, wherein the spindle bed has clamping surfaces at the spindle bed end lying opposite of a bearing element of the turning bearing, and the turning bearing has an arc-shaped clamping segment to fix the clamping surface of the spindle bed at the clamping segment with aid of a clamping device.
