After a presentation to the management team, the customer partially dumped their central system (~50%) and refilled with 2PAQ™. During the trial, Quaker provided laboratory support and weekly scheduled technical support. As a result of the trial, it was shown that improvements in biostability and reduction in costs were realized. CONSUMPTION SAVINGS Top up from 1.8% to 1,1% 40% Reduction Additive cost (biocide, coolant conditioner) from 45k€ to 4k€ 95% Reduction CHALLENGES A worldwide manufacturer of bearings located in France was looking to improve performances of its metalworking coolants. The plant, with the capacity to produce up to 20 million bearings a year, serves a broad range of customers, including PSA Peugeot Citroen, Mercedes Benz, Renault, Volkwagen/ Audi, Scania, John Deere, Volvo, Caterpillar, Linde, Fiat/Iveco, J.I. Case, Jaguar and others. They were specifically looking to alleviate the following problems: » Improve biostability of emulsion » Reduce machining fluid usage and waste » Reduce total cost Results: » Annual savings of 80 k€ » 90% reduction of waste cost thanks to an improved biostability of the emulsion (only one preventive treatment with biocide in Year 1; pH stable around 9.0; reduction of partial dump due to control of chloride level) PROCESS AND EQUIPMENT Concentration QUAKERCOOL® W ALCA BFF : 3 - 4% QUAKERCOOL® OIL HR : 0,5 - 1,5% Water TH 100 ppm / 10°f / 6°dH Material 100% Steel Operation Grinding Machines 1 central system (130 m 3 ) Filtration Permanent filtration 120µm Other Centrifuge if necessary THE PRODUCT 2PAQ™ technology is a two-component product that includes an alkaline and oil phase, typically mixed into water to prepare emulsions suitable for machining and grinding operations. When mixed alone into water, the alkaline phase can also be used as a process cleaner, and when the cleaning solution becomes too saturated, it can be reused for topping up the machining and grinding systems. QUAKERCOOL® W ALCA BFF is an innovative formaldehyde and boron-free water soluble “alkaline phase” developed to perform a wide range of machining and grinding operations on most engineering materials. It is recommended for machining operations on steel, cast iron and aluminum alloys. It has a flexible dosage, and therefore can replace different kinds of metalworking coolants including synthetics, semi-synthetics, micro-emulsions and emulsions. It can also be used as cleaner. It should be combined with a Quaker “oil phase” to give a high performance machining or grinding micro-emulsion (unless being used as cleaner or synthetic).
