In cutting tool applications, coating hardness is very critical, as well as its good coating adhesion. The flange wear on a cutter determines the tool life of the cutter. There are other features that PDLC can exhibit besides just hardness and good adhesion.
Non-sticking, for example, is one of the few very important consideration when machining soft materials like aluminium or plastics because it enhances the lifespan of the tool and increases the productivity of the tooling equipment.
Combining high hardness, excellent adhesion on tool surface and non sticking properties, PDLC makes the perfect coating on form tools for machining non ferrous material.
The PDLC coated cutters are totally protected including flute for easier chip evacuation.
