A tool unit includes a tool head, a motor and a switching drive for the head. The head has a first section with first blades and a second section with second blades. The second section is movable to and fro between a passive and an active position relative to the first section, the second blades being retracted in the passive position, and the second blades projecting axially beyond the first blades in the active position. The drive includes an electromagnet and an actuating armature made from magnetically attractable material and is arranged in the region of action of the electromagnet. The electromagnet is positioned between the head and the motor and is fastened to a housing part of the motor such that it cannot be rotated. The armature is connected fixedly to the second section. A gap remains between the electromagnet and the armature in the passive and active position.

An edge milling device is provided and includes a base platform having a working surface, at least one edge milling component displaceably disposed on the working surface for processing a side surface of a target object, a positioning structure disposed on the working surface for placing the target object, and a fastening portion disposed corresponding to the positioning structure to press the target object on the positioning structure, thereby speeding up the production and improving the production efficiency.

The disclosure relates to a processing station for aircraft structural components, having a gantry processing machine, a clamping frame for fastening at least one component, and a holding device assembly for receiving the clamping frame, wherein the gantry processing machine has a gantry and the gantry supports a processing tool which defines a processing point, wherein the processing tool is configured so as to be pivotable in relation to the gantry, and wherein the processing tool for displacing the processing point is height adjustable in the z direction in relation to the gantry, wherein the holding device assembly has at least two holding devices, and wherein at least one holding device has a drive for the height adjustment, and the clamping frame is height-adjustable in the z direction by means of the holding device.

A machine tool is provided with two vertically oriented tool spindles that are arranged to hold tools and that are movable vertically in a first direction and horizontally in a second direction orthogonal to the first direction. Furthermore, the machine tool is provided with two workpiece support devices for clamping workpieces in place. At least one of the two workpiece support devices is movable horizontally in a third direction orthogonal to the first and the second direction. The two tool spindles and the two workpiece support devices are mounted on a common machine frame with a common working space, wherein the two tool spindles are movable parallel to one another in the second direction. The two tool spindles are facing one another.

The invention relates to a machining device, in particular for machining workpieces consisting of wood, wood products, plastics or similar, said device comprising a workpiece holder for holding a workpiece during the machining, process, and a guide means for displaceably guiding a tool carriage for holding and driving a tool, the workpiece holder and/or the guide means being displaceable by displacement means in order to produce relative movement in a machining direction between the workpiece and the tool, for the machining of the workpiece. The workpiece carriage is displaceably arranged on one side of the guide means and the workpiece carriage supports two tools on one side of the guide means and in the machining direction of the workpiece, said tools being arranged next to one another.

Three systems for the destruction of the data storage portion of electronic media storage devices such as hard disk drives, solid state drives and hybrid hard drives. One system utilizes a mill cutter with which the hard drive has relative motion in the direction of the axis of the mill cutter to destroy the data storage portion. A second system utilizes a laser to physically destroy the data storage portion. The third system utilizes a chemical solvent to chemically destroy the data storage portion.
