Coolant supports efficient titanium machining

A new semi-synthetic neat cutting oil to support more efficient titanium machining has been developed by Master Chemical.

Machining titanium sees rapid tool wear. Cutting oils with a high degree of lubrication have been developed specifically for this purpose but many contain extreme pressure additives that are not suitable for all applications and indeed are classified as being environmentally hazardous.

TRIM OM303 has excellent tool life properties but importantly this is achieved without the use of chlorine or active sulphur EP additives. This is also critically important for manufacturers of titanium aircraft components. Any residue of these lubricants left on such components can, at high temperatures, cause thermal stress potentially resulting in cracking.

In trials, this product has proven its value in difficult operations on stainless steels and corrosion resistant aerospace alloys. It is particularly suited to milling, drilling, thread rolling and thread form tapping. Other characteristics include low odour, low foaming and low misting making it suitable for aggressive operations.
