The invention relates to a method and machining device for clamping and machining a control cabinet component in a machining device. The method includes the following steps: Arranging a workpiece executed as a control cabinet component on a work surface of a machining device; clamping the workpiece on the work surface, wherein a supporting unit with at least one clamping device arranged on it, is shifted to an edge of the workpiece using an actuator-driven shifting unit and a clamping element of the at least one clamping device is shifted from a released position to a clamped position when guided towards the edge of the workpiece, meaning that the clamping element comes to rest at multiple contact points on the workpiece so that the clamping element secures the workpiece in a machining position, preventing it from shifting perpendicularly to the work surface, and machining the workpiece using a machining tool.

The invention relates to pallet changers and methods for processing sheet-like materials with at least two movably arranged pallets movably positioned in a main frame and having a support surface for receiving a sheet-like material. The pallets are moved in alternation with a drive from the main frame into a material processing machine and back to the main frame. The drive comprises a motor, which drives a drive element, which moves the pallets. A processing device is provided on the main frame to process sheet-like material positioned on the pallets in the main frame.

A method and a machine tool for processing workpieces is described, comprising a workpiece movement device and a workpiece support that supports both a workpiece during a processing operation and a workpiece remainder produced from the workpiece during the processing operation, wherein the workpiece support comprises a first support portion and an additional support portion, wherein the first support portion comprises a loading-side support portion arranged in a loading region of the machine tool, wherein the additional support portion is arranged to move relative to the loading-side support portion between the loading region and an unloading region of the machine tool, wherein the unloading region is offset in a horizontal direction from the loading region, wherein the loading-side support portion is arranged to move in a vertical direction between a loading level and a bypass level located above or below the loading level.

Disclosed is a method for loading a sheet placement device of a flat bed machine tool with a material sheet, wherein the material sheet is supplied to the machining operation carried out by the flat bed machine tool, starting from a target position assigned to the machining operation in a machine coordinate system, and the flat bed machine tool comprises a camera system having at least one camera. The camera system is designed to produce captured images of the sheet placement device, which are calibrated three-dimensionally in relation to the machine coordinate system of the flat bed machine tool. The method comprises the steps: producing a captured image of the material sheet in the region of the sheet placement device; evaluating the captured image to determine an actual sheet position in the machine coordinate system; measuring a deviation of the determined actual sheet position from the target position; and using the measured deviation to align and position the material sheet.

A motorized chuck stage controlling method adapted to a wafer probing device is provided. The wafer probing device includes a control rod and a motorized chuck stage. The control rod can be moved between an upper limit position and a lower limit position, and the motorized chuck stage is moved along a Z-axis direction in response to a movement of the control rod. One purpose of the motorized chuck stage controlling method is to allow the operator to define the highest position to which the motorized chuck stage can be moved in response to the movement of the control rod, thereby preventing the probe and the wafer from colliding with each other.

A cutting machine waste extraction apparatus is provided for a cutting machine that cuts a plate where the cutting machine waste extraction apparatus is supported adjacent a cutting area at a cutting table. The cutting machine produces waste at the cutting area during the cutting of the plate where the apparatus includes a ducting system having a first duct that receives the waste from the plate, and a second duct that receives the waste from the first duct. The first duct is movable along the length of the second duct and the second duct includes a lengthwise opening which is sealed by a flexible belt. The flexible belt is deformable from sealed contact with the second duct, adjacent a junction apparatus, where the junction apparatus provides a fluid connection between the first duct and the second duct.

Apparatus for working a sheet comprising movement means configured to move at least one sheet at a time in a direction of advance, and at least one working unit comprising a working head on which there are installed at least one working tool and a stabilizer device having opposite first gripping members and second gripping members facing each other, and reciprocally mobile along an axis of grip and release to tighten said sheet between them and to release it.

A track guide for a cutting saw power tool allows the saw to slide along a track. The guide has two track sections, each with longitudinal channels. A track connector joins these sections. The connector has an elongated body with portions fitting into the channels of each track section. A rotary securing element on the connector has a cam profile and can rotate between two positions. In the first position, the connector moves freely within the channels. In the second position, the element engages the channel walls, locking the connector and securing the track sections together.

A clamping ram has a shaft with a longitudinal axis, a first end and a second end. At the second end, two arms are arranged which extend in the longitudinal direction and are mutually spaced by a gap. Each of the arms has an inner surface and an outer surface. At a free end of the arms, a radial thickening is provided on each outer surface. Between the two arms, a wedge plate is arranged so as to be movable in the longitudinal direction. In a retracted position of the wedge plate, the arms are in a compressed state and, in an advanced position of the wedge plate, the arms are in a spread state. Each of the two radial thickenings has a contact surface which, in the spread state, are each part of an imaginary surface that is rotationally symmetrical about the longitudinal axis.
