Title:
MACHINE TOOL FOR MACHINING A WORKPIECE
Document Type and Number:
WIPO Patent Application WO/2016/207223
Kind Code:
A3
Abstract:
The present invention relates to a machine tool (1) for machining a workpiece (2), comprising a spindle arm (30) with a spindle (34) for receiving a tool (35) or the workpiece (2), said spindle arm (30) for positioning the spindel (34) in a working chamber being movably attached to a spindle arm-receiving section (21) that is arranged on a machine frame (20). The spindle arm (30) for pivoting the spindle (34) comprises: a first spindle arm section (31) hinged to the spindle arm-receiving section (21) and designed as a longitudinal element and being pivotable about a first rotational axis (RI) with respect to the spindle arm-receiving section (21), wherein the first rotational axis (R1) is arranged in a first end section (215) of the spindle arm-receiving section (21) and in a first end section (315) of the first spindle arm section (31). A second spindle arm section (32) hinged to the first spindle arm section (31) and designed as a longitudinal element and being pivotable about a second rotational axis (R2) with respect to the first spindle arm section (31), wherein the second rotational axis (R2) is arranged in a second end section (316) of the first spindle arm (31) and in a first end section (325) of the second spindle arm section (32). The spindle arm-receiving section (21) comprises: a first subsection (211) and a second subsection (212), arranged on the machine frame (20) at a distance from each other to receive the spindle arm (30), the first subsection (211) of the spindle arm-receiving section (21) having a first braced drive (213) for transmission of a first torque onto the first spindle arm section (31) for a rotational movement of the first spindle arm section (31) about the first rotational axis (RI). The first spindle arm section (31) comprises: a first subsection (311) and a second subsection (312), arranged on the spindle arm-receiving section (21) at a distance from each other to receive the second spindle arm section (32), the first subsection (311) of the first spindle arm section (31) having a second braced drive (313) for transmission of a second torque onto the second spindle arm section (32) for a rotational movement of the second spindle arm section (32) about the second rotational axis (R2).
