Coil Fed Fiber Laser Cutting System

The DANOBAT Sheet Metal division has expanded its fiber laser cutting product line with the introduction of coil fed systems, which are designed to provide savings in the materials to be processed and increase productivity as a result of reduced machine downtimes.

"This machine takes full advantage of all the benefits offered by fiber laser cutting technology (efficiency, speed, versatility, minimal maintenance, etc.), as well as the benefits arising from the use of metal coils-up to 15% savings in materials cost and improved sheet utilization," said a company spokesperson.

The system is comprised of a sheet feeding line and an integrated laser cutting module that provide continuous operation. The feeding line is equipped with an uncoiler that unrolls the coil, a straightener that removes the sheet's contours and internal stresses, and a looping pit that stores the straightened material for processing. The laser consists of a fiber laser generator and a cutting head that moves in sync with the sheet to obtain the desired geometries. The exit of the cut pieces can be automated using different systems-robots, stackers, etc.-depending on the customer's needs.

The system includes the ProCutter cutting head from Precitec, which has been designed to achieve greater control of the cutting process since it is possible to monitor the state of the head at all times. A mobile phone can be used to display parameters such as:

  • Optics temperature: Lens, protective window and collimation lens
  • Pressure: Gas cutting and purge
  • Protective window pollution
  • Working distance control.

Due to its modular design, multiple heads can be integrated into the solution to increase the cutting process's productivity. The workload will be consequently distributed among the heads.

This machine can be used in different fields of application, such as: structural parts of vehicles; roof sections for metal silos; light fixture bodies; industrial filters and more.
