Metal Cutting


Kern’s CO2 laser systems can be equipped with innovative metal cutting technology. The metal cutting option allows for accurate cutting of sheet metals like stainless steel, mild steel, aluminum and brass.

An 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.

A protective K-Lens is installed within the V-FOCUS metal cutting lens assembly. These lenses are a low cost, sacrificial optic which help protect the focusing lenses from reflected laser energy, dust and debris.

The metal cutting table is constructed of durable steel grid work which minimizes the surface contact with the bottom of the metal being cut. The CAD cutting file for the individual slats is saved onto the sysems computer and replacements 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.

Kern's metal cutting technology is our most popular add-on package which allows for precision cutting of sheet metal.


Kern’s metal cutters are not just a laser with an adjustable z-axis. The mechanics and software have been designed specifically for cutting metal. Here are a few features that set us apart from the competition:

Programmable Air

A programmable air assist allows three gas types to be connected to the laser system simultaneously. The gas type needed for each job is set in the KCAM software, eliminating frequent handling of gas tanks and lines.

Pierce Control

Before you can start cutting metal the laser beam must pierce through the sheet. KCAM has multiple pierce parameters allowing users to set the power, dwell time, gas type, gas pressure and focus gap. All of this control allows for small and efficient pierces prolonging optic lifetime.

Fine Adjustments

Metal cutting can be a delicate process, especially when cutting very thin and thick sheets. Our KCAM laser software is able to adjust the power and speed of lead-ins and corners, allowing for consistent cut quality throughout large detailed files.
