The foam factor

However, Master Chemical Europe claims not only to have to have cracked this problem with the introduction of its new Trim SC415 and SC617 but also effected a number of additional benefits.

These latest semi-synthetic coolants were developed in the UK for the European market at the request of customers. Their formulation ensures low levels of foam not generally seen with other fluids of their type, especially in soft water areas. Also tolerant of hard water, the products are versatile and work well in a wide range of operations such as grinding, milling, turning, drilling and tapping.

Trim SC617 additionally contains a traditional extreme pressure (EP) additive that boosts cutting performance for difficult to machine materials. It is effective in turning stainless steel and other hard steels and its low foam profile enables its effective use in through tool machining applications.

Low consumption is another main benefit of Trim SC415 and SC617. Typically, instead of topping up with a 1-2% dilution to achieve a 5% concentration, 0.5% of the new semi synthetic is required. Indeed when trialled in a 50,000 litre central system consumption of Trim SC415, by comparison with the previous semi-synthetic, dropped by a claimed 50%.

A similar example was confirmed by a company grinding rotors at high pressure and with soft water. This combination of factors meant there was a constant need for additions of anti-foam but Trim SC415 clearly demonstrated that it did not require any such additive.

Both of the new semi-synthetics are effective on cast iron and steel machining and grinding. The clean running formulation of these new introductions prevents the build up of graphite residue that is commonly seen on machines working cast iron. They also coat the work piece and chips for excellent corrosion protection.
