5-axis fiber laser cutting system


Miyachi Unitek, Monrovia, CA, a maker of laser welding, laser marking, and laser cutting equipment, has released a new Sigma 5-axis laser cutting system that enables three-dimensional cut paths with high speed and high precision. The company says the system is ideal for thin metals with unique cut paths, non-symmetrical features, beveled edges, off axes cutting, compound angles, and internal cut radii of less than 50 μm.

The system incorporates a two axis rotary assembly, mounted to an XY stage with linear motors and high torque direct drive rotary axes. The fiber laser has focus spot sizes down to 20 μm, beam quality M2 of 1.1, and laser power levels up to 500 W, enabling laser cutting of a wide variety of metals and thicknesses. A unique position-based firing control method accommodates multi-linear 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.
