non stick-FiReNi – Development of stress compatible coating systems for the optimization of cutting tools

Situation:

• Growing demands on cutting tools regarding cutting quality when processing high-quality strip materials, e.g. special paper, FRPs, insulating materials
• Problems especially due to buildup, high friction and dust generation
• Performance of the cutting process is determined by the shape, surface and material of the cutting edge and the knife body as well as the process parameters

Solution:

• Optimization of the knife bodies by
  • Improvement of tribological conditions by means of stress-compatible coating systems, especially based on electroless nickel dispersion coatings
  • Adaptation of the knife geometry to the changed tribological conditions

Operational benefits:

• Increase of process reliability, tool life and cutting quality
• Enabling the cutting of new high-performance materials, e.g. fibre composites for wind turbines or fibre material for insulating materials

This project is supported by the European Regional Development Fund (EFRE).
