Product Focus: Laser Machining/Marking

Laser Interferometer

Zygo, Middlefield, CT, has launched a new laser interferometer, designed to support demanding metrology applications. The Qualifire weighs approximately 45 lbs. (20.4 kgs) and offers integrated phase measuring receptacle (PMR) for modulating interference fringes between the test part and reference optic, which ultimately creates a quantitative surface map. An optional module actively reduces or even eliminates artifacts. An accessible power button and kinematic mounting feet make setup easier to use. Large control knobs allow for more accurate adjustments.

Photo Chemical Etching

A special liquid-resist system and glass digital tooling from Micrometal, Muellheim, Germany, enables the creation of ultra-thin and incredibly precise components. The photochemical etching (PCE) process is highly automated and continuous, ensuring excellent reproducibility and tight tolerances. Metals suitable for etching can be both ferrous and nonferrous and include austenitic and martensitic steels, coppers, brass, and nickels. Hard-to-machine metals such titanium and its alloys and aluminum can be processed, as well as high-temperature alloys such as Inconel and precious metals including silver.

Marking Laser

TRUMPF, Plymouth, MI, has released a new marking laser for the medical industry. The TruMicro Mark 1020 ultrashort pulse laser enables cold black marking on complex 3D surfaces made of metal. Utilizing short pulses, operators can mark components and minimize heat generation. Known as black marking, this process forms a nanostructure on the surface that captures light, resulting in a deep black marking visible from every angle. This technique ensures product traceability and facilitates extended reuse. With the laser’s focus diameter of under 50 μm, users achieve precise marking even on extremely small components.

Laser Plotter System

Laser plotters from SEI Laser, West Hartford, CT, are designed for cutting and marking a wide range of materials including acrylic, ABS, plastic, and PET. The X-Series includes the X-Type Laser Plotter System (for signage), X-Wave Conveyor (for textile), and X-Wave Converting (for corrugated). The high-speed laser system for cutting rolls of organic and technical fabric can reach speeds up to 13.12 ft. (4 m) per second with an extremely precise trajectory.
