Metal Cutting with Kern

Kern laser systems can be equipped with our innovative pulsed laser technology which allows for accurate cutting of sheet metal. Commonly cut metals include stainless steel, mild steel and aluminum.
The Automatic Focusing Height Follower, developed by Kern Laser Systems, is one of the key elements for optimal metal cutting. The cutting nozzle is controlled by a capacitance sensor and z-axis motor. The gap between the metal being cut and the cutting nozzle can be adjusted until the desired beam focus is obtained. As the cutting process begins, the height follower will track the surface of the metal and adjust the nozzle in the z-axis maintaining a constant focus point while the metal is being cut.
The metal cutting table is constructed of durable grid work which minimizes the surface contact with the bottom of the metal being cut. The slat file that makes up the grid work is saved onto the computer and replacement slats can be cut on the laser system.
Advanced metal cutting features in the KCAM Laser Software allows for complete control of the metal cutting process. A laser dwell delay is available ensuring the laser pierces through the metal before the motion of the cut begins. The nozzle air pressure can be set independently for the laser dwell, normal laser cutting and jog between parts. The laser’s modulation frequency can be set from 500 – 50,000 Hz to achieve a dross free cut which eliminates the need for a secondary deburring process.
