Miyachi Unitek's Sigma XY Designed for Thin Metals
Miyachi Unitek Corp., Monrovia, Calif., has introduced its Sigma XY fiber laser cutting system, which enables high-speed precision laser cutting of thin metals using a rigid linear drive, gantry-based motion system. Combining high-accuracy linear motors with the fine spot capability of the LF series range of fiber lasers enables the Sigma XY to offer high dimensional accuracy on cutting profiles.
A proprietary laser power ramping algorithm for acceleration and deceleration provides fast cut times and consistent thermal input for stable cutting. Up to 500W of available laser power makes the Sigma XY suitable for a wide range of materials, including steels, aluminum and brass, the company claims.
Miyachi Unitek's fully integrated laser control optimizes cutting, enabling pulse widths to 20 microseconds, pulse frequency up to 50 kHz and precise control of the power. Equipped with a 4-inch-thick granite base secured to a high-strength welded steel base, the system offers the mechanical stiffness necessary to accommodate the high acceleration and deceleration rates that minimize cycle times.
