Coatings are one of the most important ways of enhancing tool performance, according to the exhibitors. The company, which develops and constructs its coating units in-house, claims to operate one of the world's largest coating centers. The latest plant generation CC800-HiPIMS will be presented, combining the benefits of sputtering technology with the options provided by the advanced HiPIMS (High-Power Impulse Magnetron Sputtering) technology. The unit has a total of six sputter cathodes that can be switched individually. Four of these can work in DC mode or in pure HiPIMS mode. As a result, it is now said to be possible to deposit pure HiPIMS coating layers economically for the first time. To produce more complex coatings, deposit colored and protective coatings or increase the coating rate, the other two DC cathodes can be switched on as desired. The plant is reportedly able to atomize practically any material. The coatings produced are apparently smooth, droplet-free and low-tension. Moreover, the high metal ionization of almost a hundred percent enables excellent adhesion and allows dense, compact coatings to accumulate that are both very hard and tough. The homogeneous plasma produces an even coating thickness on the sometimes highly complex tool geometries, even with the smallest dimensions. The manufacturers also stress that the cutting edge geometries of micro-tools are not adversely affected or rounded.
Plant and coating production dovetailed
Cemecon will be introducing the CC800-HiPIMS coating plant as its latest development. The system is described as combining all the advantages of sputtering technology with the possibilities of the HiPIM technology that allows a hitherto unknown variety of high-quality coatings.
