Decoating after regrinding can damage the final geometry of the tool and increase the risk of poor adhesion. In addition, packaging, transport and repackaging involve the risk of damaging the tool.
CT decoating systems from PLATIT set new standards in decoating, especially for carbide tools. The problem of cobalt leaching is circumvented by protecting the substrate with a TiN adhesion layer as the decoating process of the CT systems will not attack the TiN layer. For the CT20, the decoating cycle all the way to the TiN adhesion layer will take less than three minutes. The end of the process is automatically detected by built-in electronics. The adhesion layer is not removed and therefore "overcoated" after regrinding and pretreatment. A service life comparable to that of a new tool is achieved.

ST decoating units from PLATIT stand for great safety and flexibility. Depending on the module, they decoat Ti- or Cr-based coatings on carbide or high-speed steel.
