ITASCA, Ill., Nov. 19, 2012 — Keyence has introduced the MD-F5100 series 50-W three-axis fiber laser markers. The compact and fanless architecture and IP64 rating (head unit) enable use in demanding manufacturing environments. The internal components of the marking head are not affected by dirt, dust, water or oil mist. The 50-W output ensures high-speed marking and deep engraving on a variety of metal and plastic targets. New functions such as “scratch control” and “deep engraving,” along with fiber laser technology lead to improvements in marking time, production efficiency and quality. Proprietary wide-area, three-axis technology allows for consistent marking quality on 3-D surfaces and the far edges of the 300 × 300-mm marking field. The laser markers eliminate changes in character shape, distortion and beam spot size variations. Even at the edges of the area, perfectly focused marking is possible. The MD-F5100 series three-axis programming supports multiple product types being marked on the same production line. Instead of changing the machine tooling, the user can simply change the program. The wobble function reduces marking times for distinct black characters on metal without swelling or cracking.
