Water-Soluble Coolant for Metal Cutting
To obtain the best possible cutting results, an additive for recirculation units should be added. The correct cutting cooling fluid is essential for a good sectioning result.
For the best performance of the cut-off wheel we recommend that you use Aka-Cool, a water-soluble coolant. This coolant ensures that the abrasives used in the cut-off wheels are properly lubricated where the cutting takes place. This means minimum thermal damage of both sample and cut-off wheel and therefore additional lifetime of the cutting wheels. It further protects the cutting machine from corrosion and helps to reduce clogging of the debris in the recirculating cooling unit, thus facilitating cleaning of the tank. 3 - 5% of Aka-Cool is mixed with water for optimum performance. This makes the final liquid a water-based cutting coolant.
Some materials can create excessive foaming of the cooling fluid. Foam will greatly reduce the cooling ability of the cooling water and can overflow the recirculation cooling unit. To avoid foaming, Aka-NoFoam should be used.

Why can't I just use water as a cooling agent when cutting?
Very often ferrous metals are sectioned and the small chips are corroding very fast. This can destroy the cut-off machine in a very short time. If only non-ferrous materials have to be cut there are still many machine parts made of cast iron or steel that can corrode, and also therefore a suitable cutting coolant fluid should be used. Our Aka-Cool not only prevents corrosion it also increases the cooling efficiency, thus reducing thermal damage.
Do I always have to use an anti-foaming agent?
Certain materials or material and cut-off wheel combinations can create foam. As foam can result in overflowing of the recirculation cooling unit and will decrease the cooling efficiency, Aka-NoFoam should then be used.
How often should I change the cooling water on my cutting machine?
Aka-Cool is a fully synthetic product and has therefore a very long service life compared to other additives on the market. Therefore, the intervals of exchange are much longer, often defined by the amount of debris in the recirculation cooling unit.
