Trim coolant improves machine cleanliness

Master Chemical has revealed how its Trim C270 synthetic coolant concentrate has helped Sauer Danfoss eliminate mineral emulsion odours and improve machine cleanliness.

Sauer Danfoss supplies markets throughout the world with its hydrostatic transmissions, steering components, motors, valves, open-circuit products and electro-hydraulic controls.

The manufacturing site that experienced these coolant problems is responsible for the production of machine pumps.

Part of the pump-manufacturing process involves milling, drilling and grinding the pump's cast iron cover and it was the coolant in these machines that was ultimately replaced with Master Chemical's Trim C270.

This product was introduced to operate where high coolant velocities are needed to achieve maximum productivity.

It is formulated to produce little or no foam, mist or odour.

Despite being free from chlorine and sulphur, it has sufficient EP lubricity for all of the Sauer Danfoss machining operations.

In a trial using Trim, the test machine became cleaner and the fluid ran clear with no odour.

From the operator's point of view, the clarity of the fluid and minimal foaming also allowed better visibility of the machining process.

The success of this trial led to Trim C270 being installed in a further three machines.

In turn, the entire metalworking shop was changed over to this Master Chemical synthetic coolant concentrate.

Three years later, Sauer Danfoss continues to report on the cleanliness of its machines and the company also confirms significant savings too.

This is the result of a reduction in downtime of between 15-20 per cent coupled with a 25 per cent cut in fluid consumption.
