Laser Die-Cutting System Is Suited for Rapid Prototyping
A laser die-cutting system is designed to offer flexibility and precision for rapid-prototyping operations. It is suited for applications involving microperforation and complex geometries. In addition to recipe storage, batch count recording, and fault monitoring, the Delta Edge laser module features a servo-controlled robotic arm for laser repositioning. Repositioning can be performed quickly in between products so that one system can be used for a variety of web-handling processes. Digital die-cuts can be programmed into the system through the human–machine interface touch screen. Users can modify the cut depth, width, and location on demand, and no tooling is necessary to achieve or alter tight-tolerance die-cutting.

Material-Handling System Integrates Linear and Rotary Motion
A cylindrical laser processing system combines automated material handling with high-performance direct-drive linear and rotary motion to provide high throughput and accuracy. The LaserTurn 1 features an automated pneumatically actuated Type D collet closer that performs product feedthrough. It can also support tubing diameters ranging from 0.1 to 7.9 mm for dry cutting applications and up to 3 mm for wet cutting operations. The collet closer is designed to minimize axial tube motion during clamping operations by keeping the collet stationary and moving the tapered mating surface when opening and closing the collet. Both the linear and rotary axes use direct-drive noncontact motor and encoder technology. The system’s encoders are coupled directly to the load to provide high levels of accuracy and repeatability. Fixtures such as bushing alignment assemblies, part collection, and automated material advance functions can be added to the system.

Laser Micromachining Workstation Allows for Range of Wavelengths
A laser micromachining workstation allows for a range of wavelengths and laser types to be used in various applications. The compact IX-100-C accommodates a variety of accessories and options, including wavelengths from 157 to 1064 nm. It features galvanometer technology that permits an f-theta lens with a focal length ranging from 100 to 254 mm to be used with fields of view up to 170 × 170 mm. The moving mirrors of the galvanometer provide rapid scanning over a large area with reasonable accuracy, according to the manufacturer. In addition to high-accuracy motion control equipment and z-theta stage technology, the system includes fixed-beam delivery optics for high-precision applications.

System Combines Laser Welding and Marking
Made specifically for medical device applications, a station platform integrates laser welding and marking to create a turnkey system. Part fixturing and fume extraction operations are combined on a standard system with safety circuits to manually assemble and automatically weld parts, verify the integrity of the weld joint, and ensure that the part is cut to the specified length. This standard system is coupled with laser welding and cutting technology for assembling miniature components. Designed to simplify miniature part handling and assembly, the system also features part-present sensors and an automatic pull-test operation in addition to its integrated processes.
