Tool costs have a huge impact on production economy. Starting from production through
regeneration of tools. We often encounter that manufacturing companies do not want to coat their
tools because they consider it an additional cost.
Yes it’s true. However, by using PVD coatings, we can save a lot, and at the same time significantly
save on the production of new tools, regeneration, lubrication, production downtime due to tool
replacement.
Depending on the production profile, the increase in service life is from 30 to 300% and more.
Choosing the right coating is important. Coatings can be made in various technologies: PVD, CVD,
PACVD applied with electrodes.
Of course, we select the coating based on customer information. We ask in what conditions the
tools, machine element work, what material it is made of, how the thermal process proceeded, what
is the surface roughness, how the tool wears out, etc.
We pay special attention to the "cleanliness of the surface".
Usually tools are made by milling, turning, electric discharge machining (EDM) and grinding.
The manufacturing or reconditioning process of the tool may render the surface unsuitable for
coating and lead to unsatisfactory adhesion or surface roughness with insufficient lubricating
properties.
In the case of tools that are regenerated, there are often traces of lubricants, coolant, or remnants of
processed materials.
Proper surface preparation is of great importance. We often use dry ice or ablation.
