High pressure cooling

High pressure coolant delivery (to 170 Bar) offers benefits in terms of metal cutting efficiency. It can offer reductions in cycle time of up to 70% while improving the quality of surface finish, extending the life of tooling and inserts, and enhancing chip control.

Machining produces fines as well as chips – small particles of metal that are highly abrasive. Wanner says that if these are not removed from the system by ultra-fine filtration they will eventually destroy any pump where bearings and seals are exposed to the pumped coolant.

Hydra-Cell hydraulically balanced diaphragm pumps handle fines over 500mµ in diameter, removing the need for fine filtration.
