Features

Compact design of CNC-controlled machine for precise and productive cutting of plates with a “fiber” laser. This is a new generation of lasers for cutting metals, which, according to conventional CO2 laser has the following advantages:

  • For approximately 3-times better efficiency and therefore significantly lower power consumption.
  • Beam conduction is performed through a flexible optical conductor and therefore there are no particular restrictions on length of the conduction or on size of the machine,which is a prominent problem with CO2 laser due to sensitive system of mirrors for directing the laser beam.
  • The lifetime of the laser beam source is approximately 50,000 hours and requires no special maintenance, so the operation and maintenance costs are significantly lower.
  • The short wavelength of the "fiber" laser allows greater penetration at reflective metals (eg. aluminum, brass and copper), therefore also allows the cutting of such materials.


Basic machine:

  • Compact designed basic construction of the machine with built-in chambers for the extraction of gas and dust from the site of cutting.
  • Precision roller guides with roller bearings and precision and dynamic AC servo drives.
  • Complete leading machine is installed in a protective housing that meets all safety requirements for laser cutting.
  • Changeable support table for automatic grid exchange with cut parts or a new plate; enables quick material replacement.
