Abstract: A unit for machining a workpiece, in particular for machining grooves and separating cuts therein, said workpiece preferably consisting at least partially of wood, wood-based materials, metal materials or plastic, has a main body (1), a machining tool (2) which is mounted, in particular rotatably mounted, on the main body (1), wherein the machining tool (2) has a first portion (3) which is configured such that, during machining of the workpiece (10), it is able to penetrate into the workpiece (10), and a guiding device (4) which is arranged in the region preferably next to the machining tool (2) and is configured such that a medium is able to flow along, preferably through, the guiding device (4), wherein the guiding device (4) has at least one opening (5) at a lower end portion thereof. The guiding device (4) is configured such that the medium is able to flow out of the opening (5) substantially towards the first portion (3) of the machining tool (2), and/or the guiding device (4) has an extraction device.

Abstract: An exchangeable machining unit (1) for a machining centre (2) for machining workpieces (5) that preferably consist at least in sections of wood, wood-based materials, plastic or the like is disclosed, wherein the exchangeable machining unit (1) comprises a generator (10) for generating energy, selected from the group consisting of electrical, hydraulic, pneumatic, thermal energy, and radiation and vibration energy, in particular mechanical rotation energy of a drive spindle, in particular of a milling spindle, and has a drive (12) that can be supplied with energy by means of the generator (10). The generator (10) comprises an in particular releasable torque interface (14) for transmitting a torque from the outside to the machining unit (1). The generator (10) is configured to be driven by means of the torque, wherein the drive (12) is driven using the energy from the generator (10). A machining centre having such an exchangeable machining unit is also disclosed.

Abstract: A device according for coating workpieces of wood, wood materials, plastic, aluminium or the like, includes: a feed device for feeding a coating material; a pressing device for pressing the coating material onto a surface of a workpiece; a conveying device for inducing a relative movement between the pressing device and the respective workpiece; and an activation device for activating an adhesive on a coating material fed by the feed device and/or for activating an adhesive on a surface of a workpiece to be coated. The activation device includes at least one supply line for supplying an activation medium as well as a nozzle body having an activation medium inlet duct and an activation medium outlet region. The activation medium outlet region includes at least one outlet opening. The activation device also includes precisely one closure to close the outlet opening of the activation medium outlet region.

Abstract: The invention relates to a feeding device for feeding a plate-type workpiece to a machining device, said workpiece preferably being made, at least in sections, of wood, wood-based material, plastic or the like, the feeding device comprising a storage means designed to receive workpieces in a first position and a second position, said two different positions being arranged such that they provide access to the respectively provided workpieces independently of each other. The feeding device also comprises a grip device which is designed to grip a workpiece that has been received in one of the positions in the storage means, and to transport it in relation to the feeding device and independently therefrom such that said workpiece can be machined by the machining device, the gripping device then being a position to be able to transport said workpiece to the other position of the storage means and to place the machined workpiece in this position.

Abstract: The invention relates to a separating device which is used for machining of workpieces, preferably workpieces made from wood, wood materials, insulating materials or composite materials.
