Wmlizeiig ^echnik Trhnnln|la - ■)Ham - LagUUk Dedicated Coating Systems for Special Applications Tibor Cselle, Chris Galamand, Dominik Blosch - PLATIT AG, Selzach-Riaz, Switzerland Due to the increase of the special demands, PLATIT decided to specialize its team in Riaz, Switzerland to engineer and produce special machines. Coatings for cutting tools are usually produced in standard equipment. The typical coating chambers offer coating volumes of ~0300 x 300 to ~0700x700 mm. PLATIT's main business runs with the standard machines of the series 11 [1], which covers the entire spectrum of coating...

By using dedicated coatings, enormous productivity increases have been achieved (Fig. 3). Coating plants with a large chamber diameter for coating saw blades In order to increase productivity when coating saw blades, special substrate carriers are built up, which enable overlapped clamping of the tools. In the plant PL2001 (Fig. 4), which PLATIT built with 1.15 m coatable diameter for the company TRU-CUT (Brunswick,...

Fig. 4: PL2001 coating machine for saw blades User: TRU-CUT, Brunswick, Ohio, USA. PLATIT supplied the company Genta (Torino, Italy) with the PL2500 (Fig. 6b). It can pick up broaches up to a length of 2.5 m and coat up to 1.8 m working length. The machine works with four cathodes, two on top of each other on the opposite sides of the chamber. They each coat 700 mm, resulting in 400 mm missing for direct coverage of the total height of 1.8 m. The coating thickness distribution can be opimized with the help of more cathodes. This year there is a machine in the project stage, which also receives...

process. The extremely smooth DLC 2 (Sa<20 nm) layer is deposited as silicon doped amorphous carbon with hydrogen; a-C: H: Si [1]. This combination of PVD and DLC coatings offers very good adhesion, smoothest surface finish with good hardness. Their main applications for this process are – high quality machine components, medical devices, aerospace components, as well as – cutting tools for composite materials with affinity for built up edges, and – stamps, dies, and cutting tools.
