A machine tool for processing workpieces, in particular metal sheets, has a punching device and a laser processing device. The punching device comprises a punch-side positioning device by means of which a punching tool component of a punching tool can be positioned in a definable position along an operating stroke axis of the punching device. The laser processing device has a laser processing unit and a laser accessory unit. The laser accessory unit can be positioned by means of an accessory unit positioning device with an activation movement in an operating position which can be defined by means of the punch-side positioning device. In the context of a method for processing workpieces, in particular metal sheets, which method is carried out using the above machine tool, the operating position of the laser accessory unit is defined by means of the punch-side positioning device.

A frame includes a plurality of frame segments, each secured to an associated one of the distal sidewall ends. A plurality of actuators, each located with one intersection of the plurality of frame segments, linearly move its associated one intersection of the plurality frame segments so a plane formed by the frame segments remains parallel to a planar surface.

A laser etching apparatus includes a chamber, a laser port, a laser emitter, a particle grabber, and a revolving window module. The chamber is configured to receive a substrate. The laser port is disposed below the chamber in a downward direction. The laser emitter is configured to emit a laser to the substrate disposed within the chamber through the laser port. The particle grabber is disposed within the chamber and includes a body disposed over the laser port. An opening is formed through the body. The opening is configured to pass the laser therethrough. The revolving window module includes a revolving window and a driving part configured to drive the revolving window. The revolving window is disposed between the particle grabber and the laser port.

Disclosed are methods and coatings for protecting the surface of a non-metallic composite part, comprising applying a protective layer to an exposed surface of the non-metallic composite part, the protective layer comprising: (a) a multilayer having at least a co-cured layer applied to the surface of the non-metallic part and laser-sensitive layer applied to a surface of the co-cured layer, wherein the laser-sensitive layer is selected from a reflective layer, an optical sensor layer or a layer having both reflective and optical sensor properties; or (b) a co-cured coating which comprises a laser-sensitive material incorporated therein to form a laser-sensitive co-cured layer applied to a surface of the non-metallic composite part, wherein the laser-sensitive material is selected from a reflective material, an optical sensor material or a combination thereof, such that the non-metallic composite part will be protected from damage during subsequent laser ablation to remove an outer coating.

The invention relates to a device for roughening cylinder bores using a beam tool and offering a very high level of process reliability even for a large quantity.

A laser system includes a controller, a laser source, a laser scanner, and a laser containment apparatus. The laser containment apparatus includes a mounting structure for the laser scanner, a shroud assembly coupled to the mounting structure, and a seal interface coupled to the shroud assembly at an opposite end from the laser scanner. The shroud assembly surrounds a working volume of the laser scanner and includes a vacuum port connected to a vacuum source and a purge port that guides purge gas from a purge gas source toward the laser scanner. A distal end of the seal interface is formed of a pliable material that compresses to seal the shroud assembly to a target surface of a workpiece upon establishment of a negative pressure differential between a vacuum pressure inside the shroud assembly and ambient atmospheric pressure.

In some examples, systems and techniques for repairing or otherwise forming a blade of a bladed disk. In one example, a method including positioning a shield member around a perimeter of a partial blade extending from a rotor disk of a bladed disk, the shield member being positioned adjacent to a build surface of the partial blade; and depositing, with the shield member around the perimeter of the partial blade, a material on the build surface using an additive manufacturing technique to form a repaired portion on the build surface of the partial blade.

This application relates to a protective apparatus. The protective apparatus is configured to protect a to-be-welded part, the to-be-welded part includes a welding region, and the protective apparatus includes a base and a protective mechanism. The base is configured for embedding the to-be-welded part. The protective mechanism is connected to the base. The protective mechanism includes a welding hole, where the welding hole is provided corresponding to the welding region; and a surface of the protective mechanism facing the welding hole is provided with a thermally conductive coating, where the thermally conductive coating is configured to guide substances formed in welding the to-be-welded part to slide down along the surface of the thermally conductive coating. The protective apparatus in this application can improve welding quality of the welding region, thereby enhancing performance of the to-be-welded part.

A processing system has: a housing in which an object is housed and that has a part through which light is allowed to pass; an irradiation apparatus that emits a processing beam for processing the object; a first member which an energy beam from the irradiation apparatus that propagates toward an outside of the housing through the part enters; and a second member which the energy beam through the first member enters, the first member reduces an intensity of the energy beam that enter the first member, the second member reduces an intensity of the energy beam that enters the second member from the first member.

A three-dimensional laser cutter can be disposed in a machining room. The machining room includes a ceiling and a plate member. The ceiling is provided with a suction port connected to a suction device. The plate member is disposed below the ceiling with a gap therebetween. The plate member forms a space with the ceiling.
