Product Focus: Laser Machining/Marking

Laser System

ACSYS Lasertechnik, Lenexa, KS, has released a patent-pending, ultra-short pulse quick-change laser system for marking, engraving, and cutting for medical device applications. The All-In-One laser system uses a galvanometer scanner equipped with either f-theta marking optics or a laser cutting head. When in marking mode, this system can perform corrosion-free laser marking on stainless-steel devices for UDI markings on medical devices or instruments. In cutting mode, the cutting head replaces the galvanometer scanning f-theta lens without having to remove the galvanometer head itself. This laser system optimizes the cutting face the cutting joint in a targeted manner with no burrs and minimal thermal influence.

Flux-Cored Wire

Indium, Clinton, NY, has released a uniquely formulated flux-cored wire that combines superior wetting speed and spread with extremely low-spatter performance. CW-232 is a highly activated rosin flux-cored wire developed to meet the demanding requirements of robotic and laser soldering applications by delivering additional wetting power in order to achieve higher throughput. The wire also works in hand-soldering applications. Due to its “no-spatter” technology, it eliminates flux spattering that can burn operators’ hands, impair the vision system of the robotic soldering machines, or make finished products less aesthetically appealing.

Electrochemical Surface Grinders

A burr-free electrochemical cutoff machine from Glebar, Ramsey, NJ, enables multiple tubes to be cut to length at the same time. The Tridex Technology CS1-E features a highly precise feed system that can be accurately positioned to 0.00040 in. (0.01 mm). The Tridex ECC machines can cut off and grind notches in the same operation. In a typical example, using ECC 89, 25 G (0.020 in. diameter) hypotubes are cut per cycle. The cycle time is 20 seconds or 0.23 seconds per piece. The machine is simple to set up and operate via intuitive software and controls. The software collects shop floor data for OEE and process monitoring.
