Manufacturing processes in machining centers have driven capabilities to unimagined heights in recent years. They require tools that can withstand the highest loads in terms of rotational speeds, operating temperatures, cutting speeds and service life.
In addition, the finished coated surface must prevent the removed material of the workpiece from sticking to the tool. For this purpose, the coating unit must be as efficient as the tools that are PVD coated.
Rollers are a special case among tools: They are heavier than many other tools, and their size and special geometries alone make them a challenge for series coating units. Many conventional PVD coating units are simply unsuitable for coating them.
We have developed custom coating solution Mega-PiMS designed specifically for the PVD coating of oversized rollers, overcoming the problems of conventional units.
