The range of coatings available at ZWT is fully geared to the requirements of the tools. In the following we give you an overview of the coatings offered by ZWT:
STiN = titanium nitride, layer thickness 2-3 µm, universal layer for machining, forming, threading. Application temperature up to approx. 600°C, colour gold.
ALCRO-NANO = aluminium-chromium-nanocoating with particularly high hardness and excellent temperature resistance. This ensures better tool life and high surface quality. Depending on the type of application and wear, this coating requires a layer thickness of 3-5 µm and is also suitable for dry machining, colour grey-purple.
TiAlN = titanium aluminium nitride, layer thickness 2-3 µm. TiAlN has a higher temperature stability (up to 700°C) compared to TiN, but also a lower thermal conductivity. Used as high performance coating for indexable inserts in machining (drilling, milling, reaming, turning), colour grey blue.
TiCN = titanium carbon nitride, layer thickness 2-3 µm, high hardness. Despite its high hardness, TiCN is not too brittle, therefore it is well suited as a coating for cutting tools as well as for milling, tapping, punching and forming, colour grey.
This also includes permanent quality control of the coating thicknesses. The processes at ZWT are completely monitored and documented so that problems in the coating process can be detected immediately and reacted to quickly. We will be happy to advise you personally and also enable you to carry out quick tests with our various coatings.
