Product Focus: Laser Machining/Marking

Green Laser Marking System

FOBA, Wood Dale, IL, has developed a 532 nm wavelength green laser marking system, designed to offer new possibilities for industrial direct part marking. The low-heat laser applies perfect marks on materials with extraordinary absorption properties. Such materials include white, transparent, or red plastics as well as highly reflective metals. The green laser enables an increase in marking speed and marking quality on previously insufficiently markable materials. Affected materials include special plastics like UHMWPE, HDPE, or PMMA for which additives might no longer be necessary, as well as glass or shiny substrates.

Universal Machining Center

GROB Systems, Bluffton, OH, offers a five-axis machining center with optimized milling performance for a broad range of part materials. The G550 Generation 2 is equipped with a Siemens 840D SL control, 16k rpm spindle, and an HSK-A63 tool interface. It includes a horizontal spindle position that enables the longest possible z-travel path and optimum chip fall. The arrangement of three linear axes offers maximum stability by minimizing the distance between the guides and the machining point (TCP). A tunnel concept allows the largest possible component to be swiveled and machined within the work area without collision.

Laser Processing workstations

A laser processing workstation from Amada Weld Tech, Monrovia, CA, can be integrated with a range of lasers for medical device welding. The WL-300A can incorporate galvo scanning motion with XY Cartesian motion to address complex part geometries. The company also offers a low-power linear DC micro spot welder with the SL-323A high precision, low force electromagnetic weld head. The UB-1500A product combination was designed specifically for applications requiring precise positioning and force. Finally, the SIGMA® LS laser micromachining subsystem is a femtosecond laser-integrated module designed for high-precision processing versatility. The small form factor and integration-ready design control resulting in robust, repeatable micro-welds commonly required in the medical device manufacturing processes.

Laser Scanners

A laser scanner from Micro-Epsilon, Hessen, Germany, has a rear cable outlet that includes an integrated cable, which reduces by half the space required to install the scanner. In addition, a protective housing is available that offers connections for air purging as well as liquid cooling, optimizing the laser scanners for measurements in harsh industrial environments. The rear cable outlet in the scanCONTROL 30xx model options allows the sensors to be positioned in a space-saving manner. The cable length is 30 cm, and there is no wiring at the top. Compared with the standard model, this reduces the required installation space by almost 50 percent.
