CUTTING TOOLS Platit-CT decoats in less than 30 minutes Productive Decoating of PVD Coatings The decoating of cutting tools for regrinding is an important precondition for their recoating with high quality [1]. The methods known today are slow. This article presents a new, fast decoating process and the decoating system developed for this purpose. 1 The Platit-CT decoating system BY CHRISTIAN BÜCHEL, GUNNAR LAHTZ, BIRGIT WITTEL AND TIBOR CSELLE →In May 2014, the importance, requirements and latest technologies currently available were summarized in detail at a special workshop [2]. As a result,...

31 Elements of the Platit-CT decoating system The end of the decoating process can be detected by the built-in electronics that simplifies the daily practice of the operator greatly. This fast decoating also increases flexibility through the reduction of the decoating time. Its flexibility is of huge importance for small regrinders, they are incessantly struggling with large job coating centers. The decoating process during the reprocessing of the tools no longer takes most of the time (collecting-decoating-regrinding-recoating-delivering). The decoating recipes and decoated tools The decoating...

4 Comparison of bath preparation, lifetime and decoating times of solid carbide shank tools with conventional and CT process The productivity increase As mentioned in the introduction, the productivity, the short execution time of the decoating, is important so that the recoating of the tools does not suffer any delay. Figure 4 compares, by way of example, the bath preparation, lifetime and decoating times of the conventional and Platit-CT processes for carbide shank tools.
