Tool resharpening or repolishing: giving the tool multiple life cycles

PVD and CVD coatings allow to increase the hardness of a cutting tools edge, hence increasing both the lifetime and output of the tool. But the coating may wear and the tool will need to be resharpened and repolished.

For parts such as hobs or injection molds, where the tolerance on the produced parts is strictly controlled, it is essential that the coating is removed without any damage to the substrate.

The NGL decoating range allows precise and safe decoating of most coatings on both HSS or carbide tools.

Coating default

PVD coating is very sensitive and many issues can occur in the surface preparation process prior to coating, as well as problems during the coating itself, such as arcs formation or adhesion issues.

An insert or a drill which has coating defects or does not match the necessary coating thickness will be useless and in order to avoid scrapping these costly tools, decoating is the only professional option.

Safety first

NGL chemicals are designed to mitigate risks to the maximum, by looking for the best compromise between efficiency and safety in the composition of the products.

Steel decoating

  • FERRODEC 56  : Powdered product for the decoating of aluminium or titanium based layers on steel tools.
  • EXCARBONITE 222 : Powdered alkaline liquid product for the decoating of chromium or silicon based layers on steel tools.

Carbide decoating

  • UNICERAL 308 : Acidic liquid product for the decoating of titanium, aluminium or zirconium PVD layers on carbide tools.
  • CERALTIN 211 : Alkaline Liquid product for the decoating of chromium or silicon based layers on carbides.
