Abstract
A machine tool, in particular a multi-spindle and/or double-spindle milling machine, comprising a machine frame, a workpiece clamping device for clamping a workpiece, an axis slide assembly which is arranged on the machine frame and is configured to linearly move the workpiece clamped on the workpiece clamping device by way of two controllable linear axes in a Y-direction and a Z-direction, and a spindle carrier assembly, which is arranged on the machine frame and has at least two tool-carrying work spindles that can be moved independently of each other in an X-direction which is perpendicular to the Y-direction and Z-direction.
Claims21
A machine tool, comprising:
- a machine frame;
- a workpiece clamping device for clamping a workpiece;
- an axis slide assembly arranged on the machine frame and configured to linearly move the workpiece clamped on the workpiece clamping device by way of at least two controllable linear axes;
- and
- a spindle carrier assembly arranged on the machine frame and having at least two tool-carrying work spindles;
- wherein a first work spindle of the at least two tool-carrying work spindles is moveable linearly by way of a third controllable linear axis perpendicularly to the respective two controllable linear axes of the axis slide assembly between a first processing position of the first work spindle and a first tool change position of the first work spindle, and
- wherein a second work spindle of the at least two tool-carrying work spindles is moveable linearly by way of a fourth controllable linear axis parallel to the direction of the third controllable linear axis between a second processing position of the second work spindle and a second tool change position of the second work spindle,
- the machine tool further comprising a tool magazine that has a tool magazine carrier arranged on the machine frame and configured to have available a plurality of tools and that by way of the fifth linear axis is moveable perpendicularly to the directions of the third and fourth linear axes and in particular parallel to the spindle axes of the two tool-carrying work spindles.
