Machine tool and method for machining a workpiece

A method for machining a workpiece with different tools comprising:

• providing a machining center comprising:
• a set of tools which comprises at least first tool and a second tool, by means of which different machining operations are conductible on the workpiece;
• wherein the first tool is a drilling tool;
• at least on tool spindle, to which one tool of the first tool and the second tool is detachable fixable and by means of which the first tool or the second tool is rotatable;
• at least one workpiece support;
• wherein the at least one tool spindle and the at least one workpiece support are displaceable relative to one another, wherein the at least one tool spindle is held on a support arrangement and is displaceable at least in a first direction and in a second direction lying transversely to the first direction;
• wherein the at least one tool spindle comprises a housing;
• wherein the at least on tool spindle comprises a loading device, which is mounted in the housing and which acts on at least one linearly movable rod of said first tool or second tool being fixed to the at least one tool spindle;
• wherein the loading device has at least one linearly movable rod, to which the at least one linearly movable rod of the first tool and second tool is couplable;
• wherein the at least one tool spindle comprises a motor device, which is arranged in the housing and which is coupled to the loading device;
• and
• wherein the motor device linear displacement of the at least one linearly movable rod of the loading device, and the at least one linearly movable rod of the loading device in turn can drive linear displacement of the at least one linearly movable rod of the first tool and second tool;
• holding the workpiece in a single chucking arrangement;
• machining the workpiece with the first tool and then with the second tool;
• wherein the first tool and the second tool are respectively held on the at least one tool spindle, and the at least one tool spindle effects rotation of the corresponding tool about a rotational axis;
• and
• acting on and displaying by means of the motor device, the at least one linearly movable rod of the first tool or the second tool;
• wherein the linear displacement of the at least one linearly movable rod of the first tool or second tool effects a transverse movement of at least one cutting edge or cutting edge arrangement of the respective tool in relation to the rotational axis.
