Uncoated collets are affected corrosion in a short time due to various causes such as humidity, coolant, cleaning fluids, salts, and gas. It will affect not only the collet but also the whole process. To prevent the corrosion, GERC Collet dramatically increased tool life and accuracy by special steel material and heat treatment.

Effectively protect the collet by surface coating with micrometer which will slow down the corrosion period and maintain accuracy for long term

Rusting of the collet will caused shortening the tool life and reduces accuracy, so it effectively protects the collet by coating the surface in micro units and prevents corrosion in the long term.

Reducing the defected rate by reducing tolerance of tools in manufacturing process and increase the tool life by good concentricity and save time and cost in setting time.
