Neosol full oil emulsion has foam problem beat

Neosol 300 is a full oil emulsion, has all the machining properties of an emulsion but acts like a full synthetic. Foam is virtually non-existent, even at high pressures, and Neosol products are ideal for soft water areas. Many of today’s expensive machining centres are fitted with high pressure through tool coolant systems. As part of this package they are nearly always fitted with high efficiency filtration systems. These are designed to remove all foreign contaminants from the coolant but are also good at removing the defoamer from the coolant. For the best tool life and component quality such machines should use full emulsion coolants but the combination of high coolant pressure and defoamer removal results in high levels of foam, which is nearly impossible to control due to the filtration system. Consequently most users revert to semi-synthetic or full synthetic coolants, compromising on performance but gaining lower levels of foam. The situation is further compounded on machines where grinding heads are employed. Hangsterfer’s Laboratories have been working on this problem for some time now, the result of their labours is a new range of coolants designated Neosol. Stability is excellent. For example Neosol 300 has proven to be stable right down to 1 to 2 per cent and has a recommended operation dilution of around 4 to 5 per cent. At this figure, Neosol 300 gives a machining performance equivalent to a high quality emulsion working at 10 per cent. It is designed to be used on all types of materials including aerospace alloys, both machining and high pressure grinding. At the other end of the scale Neosol 100 is designed specifically for cast iron. The unique chemistry eliminates rusting and resists solidification of the resultant swarf. Machines are kept clean with little residue.
