Laser cutting system enables 3-D cut paths -

Miyachi Unitek Corp. offers the Sigma five-axis fiber laser cutting system, a technology that enables 3-D cut paths. The system features high-speed, high-precision, position-based firing laser power control which accommodates multilinear and rotary axis motion to control the laser pulse frequency for consistent pulse overlap according to the position of the laser spot on the part.

The flexible system configuration of a two-axis rotary assembly mounted to an XY stage helps maximize laser on-part accessibility, system simplicity, and tooling path efficiency for cutting thin metals with unique cut paths, nonsymmetrical features, beveled edges, off-axes cutting, compound angles, and internal cut radii of less than 50 microns.

Features include linear motors and high-torque, direct-drive rotary axes. The LF series fiber laser handles focus spot sizes down to 20 microns and offers high pulse frequency, excellent power and pulse stability, fine control of pulse width, and laser power levels up to 500 W, which enables cutting of a variety of metals and thicknesses.
