Technical magazine for cutting tools and measurement in the manufacturing

. Wmlizeiig ^echnik In 2006/07, the company L.E.K. [1] conducted a large-scale survey among the users of PVD coatings. The main question related to the issue as to which criteria were most important when using coatings. The majority of those surveyed were mainly medium and small tool grinders. The answers and their rankings according to importance gave clear reasons (Figure 1) as to why in-house coating has spread so rapidly in recent years compared with coating services. Priority 1: Response time (delivery time, production time) No tool coating provider can pick up, coat and return the tools...

- The user primarily expects the jobcoating provider to take care of his weekly "needs". - When choosing the system supplier of an in-house coating, he must first see whether he will be getting a turnkey solution (Figure 3) with complete know-how from a single source [2]. Priority 6: Price, costs, profit Service coating was a moneymaking machine in the 80s, 90s as well as at the beginning of the new millennium. But it is still very profitable even today. The statement by the tool manufacturer Gunther Wirth: "The coating plant? That was the best innovation of my professional life." is very true....
