The LVPLUS from Mitsubishi Laser (Wood Dale, IL; www.mitsubishi-world.com) is constructed in a heavy-duty one-piece machine design. A solid Dianite casting delivers stability with machine tool, resonator, and power supply incorporated onto a single platform. The company’s Diamond Path technology maintains consistent beam quality by using a constant beam length system. It provides cutting stability at speeds up to 1150 inches per minute across all processing areas. The system’s advanced processing head has multiple features that enable high-speed cutting on a broad range of materials. MELS EYE, Intelligent Process Monitoring System has auto focusing and other detection features to ensure superior cut quality. Burn detection tracks each cut and when no longer sustained LVPLUS automatically restarts. Pierce detection increases productivity by eliminating the buffer in conventional oxygen piercing. Plasma detection minimizes scrap in high production runs by tracking plasma and adjusting the machine’s speed as necessary. The system is completely modular and allows for 24/7 unattended processing.
New from Time-Bandwidth Products (Zurich, Switzerland; www.tbwp.com) the Duetto laser head contains a fully integrated, passively modelocked seed laser (based on the OEM Lynx laser) and a diode-pumped amplifier. Reportedly the stability and reliability of the seed laser enabled by the company’s SESAM technology and the proprietary amplifier results in clean, high-energy picosecond pulses with excellent beam properties. Applications include high-repetition-rate materials processing, micromachining, UV generation, and OPO pumping. The company also offers Fortis, a mode-locked, thin-disk laser featuring 1 µJ per pulse with 50 W output power.
Material handling system
