Bystronic The latest fiber laser cutting machine in the Bys- tronic portfolio that will process material thicker than ¾" is the BySprint Fiber 6 kW with Power Cut option, available as the 3015 model (5 × 10’) and 4020 model (6 × 13’). The new Power Cut option “enables the cut-


ting of thicker materials with the addition of larger gas piping within the machine, a Cross Jet oil spray system to assist with the piercing of thicker materi- als and special software designed specifically for the piercing and cutting of thicker materials,” Arteaga said. With Power Cut, steel thickness is increased from ¾ to 1"; stainless steel and aluminum from 0.625 to 1.180"; brass from 0.375 to 0.625"; and copper from 0.375 to ½".


Mazak


Mazak’s newest turnkey system is the OPTIPLEX 3015/4020 Fiber 6kW paired with the Compact Hi-Speed Expandable Automation System. The system “offers superior edge quality, more stable cut performance and greater throughput for applications utilizing stainless steel, copper, brass, bronze, aluminum, hastelloy, inconel, titanium, thin-gauge mild steel, and other exotic metals,” Swearingen said. “There is no need for additional surface cleaning when painting mild steel cut with nitrogen.” The OPTIPLEX uses Mazak’s Intelligent Tech- nology to increase productivity by allowing the machine to optimize the torch setup automatically per program. “This optimization can dramatically improve cut speeds, increase throughput and re- quire less operator intervention,” Swearingen noted. “The combination of fiber beam diameter and focus control provides a wide range of improved cut performance. The eight-position nozzle changer facilitates unattended operation while ensuring the proper cut quality and maintaining the lowest pos- sible gas consumption.” The system also features the new Preview 3 control with 15" touch screen and graphical interface that clearly visualizes cutting path and automatically determines process conditions including the required lens, nozzle, feed rate and laser output for different materials and thicknesses. The OPTIPLEX can process sheets up to 5 × 10' (3015 option) or 6 × 12' (4020


option) is available at 2, 4 or 6 kW. LF16 AdvancedManufacturing.org


Murata Murata’s LS3015FC, available in 2.5, 4 and 5 kW,


include a chiller and resonator, a chiller for the linear drive system and dust collection system. Automatic nozzle changers and other automation are optional. Table size is 5 by 10, with 6 by 12 arriving next year. “Our fiber lasers were developed to be a high-end fiber laser, with the same emphasis on precision, reliability, and strength as is built into our turret punch press line,” Cloward explained. “Many competing machines have incorporated a fiber system into an existing CO2


body, which


may not have been built to sustain positioning and repeatability at such high speed over time. In addition to an extremely rigid structure, we have linear drives on the X, Y and Z axes. This allows us to maintain tight tolerances while operating at high speeds, with positioning being ±0.0004" and repeatability being ±0.0004, and simultaneous traverse speed at 13,385 ipm.” The company offers three modes: high quality, with emphasis on cut; economy, to balance quality and speed; and high speed, for fastest production.


Prima Power The company recently introduced its Laser Genius, said Mike Millette, 2D laser production manager for Prima Power North America. The company offers 2 to 6 kW at 1.5 × 3 m and 2 × 4 m working areas. “The nice thing is that it has an all-linear motor,


so they’re extremely fast,” Millette said. “They’re 2.5g with traverse speeds of 10,000 ipm, and they have automatic focus, automatic nozzle centering, nozzle tip changers, all the latest nozzle cleaning— and they’re completely user-friendly. The software is easy to use for first-time laser users. With the introduction of the fiber, systems have gotten all that much simpler. So we had to make everything else simpler; no lens changes, anything like that. So we’ve taken a lot of ... the ‘black magic’ out of laser cutting.” To cut thick and thin materials, “we have focused on the larger focal-length lens” of 7½". “We lose a little speed on lighter-gauge materials, but the entire process window for thin and thick is much bigger for our machine than for most. The 7½ gives us enough kerf width to cut from 1" mild steel to ½" stainless steel and 3/8 aluminum — and that also helps us get thicker parts out. By not going with a beam-shaping
