Precision laser control

All-in-one I/O module for laser processing

CNC module for precise and fast laser processing

Controlling the laser beam source, controlling the distance of the cutting head with built-in optical focusing, as well as the reliable protection of the cutting nozzle are crucial for the highest quality and productivity of your machine.

These requirements are met through functions controlled directly from the CNC kernel as well as synchronized and instantaneous signal processing. The laser control module built into our CNC automation package implements these requirements precisely and comprehensively. Even special periphery modules such as galvanometric scan heads can be controlled without any additional hardware or costs.

Your benefits at a glance

Consistent cutting quality regardless of processing speed
Highest precision thanks to position-synchronous laser pulses with 20 ns resolution and repeatability (+/- 20 nm at 1 m/s)
Speed-independent beam intensity through closed-loop laser power control
Protection of the optical focusing unit through dynamic distance control of the cutting head

Flexible and fast solutions

The CNC laser module contains all necessary interfaces for controlling and evaluating the laser periphery. The comprehensive system integration ensures an easy, error-free installation and thus the quick commissioning of the machine. In addition, integration into the system-internal voltage supply provides for controlled behavior in the event of a grid loss.
A direct high-speed communication interface connects the CNC to the laser module. This ensures signal processing practically without delay.
