High-pressure coolant pump for machine tools from AxFlow

Using this Werner coolant pump on machine tools makes it possible to machine faster, improve surface finish and extend tool life.

Wanner high-pressure coolant pumps can deliver flow rates from 4 to 120 L/min at a pressure of 70 bar as standard, or 170 bar on a case-by-case basis. They are especially well suited to emulsions or loaded neat oils, which makes it possible to reduce filtration to 200 microns.

Their patented balanced-diaphragm technology has low maintenance costs and allows continuous use for up to 45 000 hours.

These coolant pumps are more economical than piston, gear, screw or multi-cell pumps.

The benefits of high-pressure coolant are tangible:

- In grinding:

A first high-pressure jet cleans the grinding wheel and preserves its cutting ability. More material is removed, chatter is eliminated and the number of passes is reduced. A second jet, aimed directly at the machining point, maintains the metallurgical quality of the part and improves its finish by cooling the contact point. Burns, cracks and deformations are avoided.

- In deep-hole drilling:

High-pressure lubrication breaks up and ejects chips faster and cools the tool. Drilling speeds are increased by 50 to 100% without compromising tolerances. Tool life is extended.

- In turning:

High pressure prevents sticking and provides a better surface finish.

- In milling and boring:

Chips are removed more quickly to prevent clogging, sticking and re-machining of chips.
