Product Description
Coomcool Form ST 12 is a medium viscosity, neat forming oil containing high levels of advanced lubricity and extreme pressure additives. It is free of chlorine and heavy metals, such as Barium.
Advantages
- Superior adhesion and wetting performance provide homogenous lubricating film which delivers best machining results, even on difficult geometries.
- Bright surface finish and cleanly sheared straight edges, especially on fine blanked components of sheet metal thickness up to 6 mm.
- Extreme resistance to pressure and high protection against wear enables long tool and die life and thus cuts downtime and tooling costs.
- Reliable corrosion protection reduces scrap rate.
- Chlorine and heavy metal-free technology improves the environmental profile and minimises waste disposal costs.
Applications
Coomcool Form ST 12 has been specifically developed for light-medium duty fine blanking applications of carbon steel parts, such as automotive gear box and transmission parts, window lock parts etc. The product shows reliable performance at medium steel sheet metal thickness.
