Sigma 5 Axis Fiber Laser Cutting SystemMiyachi Unitek Corp. has introduced the Sigma 5 axis fiber laser cutting system, a technology that enables 3D cut paths. The Sigma 5 axis fiber laser cutting system features high speed, high precision, and position-based firing laser power control that make it suitable for use in cutting thin metals.

The flexible system configuration of a two axis rotary assembly, mounted to a xy stage, maximizes laser on-part accessibility, system simplicity, and tooling path efficiency. Linear motors and high torque direct drive rotary axes on the laser cutting system have been optimally configured to provide high performance speed while maintaining part dimensional accuracy. The LF series fiber lasers handle focus spot sizes dow to 20 microns, and offers high pulse frequency, high pulse stability, fine control of pulse width, and laser power levels up to 500 W. The position-based firing control method 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.
