Machine tool comprising a lateral contact body and an abutment body

A machine tool for machining workpieces using a working tool, wherein the machine tool comprises a machine base for supporting the machine tool and a drive assembly arranged thereon with a drive motor and a tool receptacle drivable by the drive motor for the working tool, wherein the machine base comprises:

• a support surface for supporting the workpiece;
• a holding device fixed to the support surface;
• at least one side contact body slidably mounted on the holding device whereby the at least one side contact body is slidably movable with respect to the holding device between at least two different longitudinal positions along a longitudinal axis, the at least one side contact body having a side contact surface extending along the longitudinal axis and a guide groove formed in the side contact surface at an angle with respect to the longitudinal axis;
• and
• at least one abutment body movably supported on the at least one side contact body, the at least one abutment body comprising:
• an abutment surface for supporting the workpiece for machining by the working tool adjacent to the side contact surface between the support surface and the abutment surface, the abutment surface of the abutment body being an elongated surface extending in a direction parallel to the longitudinal axis;
• a fixing device for releasably fixing the at least one abutment body to the at least one side contact body;
• and
• at least one guide projection engaging the guide groove formed in the side contact surface of the at least one side contact body for linearly adjusting the abutment body in an axial direction along an adjustment axis with respect to the at least one side contact body, the adjustment axis being angled to the longitudinal axis,
• wherein the at least one guide projection of the at least one abutment body and the guide groove formed in the side contact surface of the at least one side contact body comprise positively engaging interlocking anti-rotation contours for non-rotatably holding the abutment surface with respect to the support surface, and
• wherein the fixing device comprises clamping means with a clamping body, which is adjustable between a clamping position and a release position, the clamping body being movably mounted on the abutment body and being received in the manner of a sliding block or grooved track in a receiving groove on the side contact body, the receiving groove having inwardly projecting projections incorporated on the side contact body, and
• wherein the clamping body is movable into the clamping position or into the release position by actuation of an actuating mechanism, such that, in the clamping position, the clamping body engages the inwardly projecting projections of the receiving groove for a clamping fit of the abutment body on the side contact body, and, in the release position, the clamping body is movable relative to the receiving groove and thus the abutment body is movable with respect to the side abutment body, and
• wherein the actuating mechanism comprises a screw.
