Stable processes with no additives: müller co-ax places its trust in the expertise of Blaser Swisslube

B-Cool MC 660 impresses with its high stability, very good lubricating performance and excellent rinsing behavior

In its search for an effective and stable coolant, müller co-ax tested a number of different solutions over several years – but the results were rather less than satisfactory. It was Blaser’s B-Cool MC 660 that finally made the breakthrough possible: stable processes with no additives, cleaner machines, and markedly lower coolant consumption. Blaser Swisslube’s holistic approach has transformed coolant into a “Liquid Tool” that plays an active role in enhancing both process security and economic efficiency.
Pioneering spirit and innovation have shaped the history of müller co-ax gmbh right from the start: With its invention of the coaxial valve back in 1960, the family-owned company based in Forchtenberg (Germany) laid the groundwork for a technology that is now used in demanding industrial applications worldwide.

Today, more than 300 employees at its headquarters in Germany manufacture customer-specific valve solutions for extreme operating conditions – such as high-pressure applications of up to 1,000 bar, or temperature ranges from –196°C to +400°C. The wide range of options available and the ability to process anything from steel and stainless steel to non-ferrous metals or high-alloy materials attest to the company’s technological standards and high level of vertical integration. From aviation and aerospace to hydrogen, oil and gas, as well as from the chemical industry to mechanical engineering, the valve manufacturer has delivered an impressive performance across all industries worldwide. Staying true to its guiding motto: Pioneers forever!

The push for stability proves worthwhile

For many years, müller co-ax had been on the lookout for a suitable coolant. Earlier solutions were increasingly unable to meet the performance levels required of them. Residue, unstable processes and the constant need for additives made day-to-day production more difficult. At the same time, there was growing demand for a coolant that could reliably process a wide array of materials.

Robert Christ, Head of Production at müller co-ax, explains: “Coolant is a system critical component in our operations. We demand a lot from it – using it to process materials ranging from steel and stainless steel to non-ferrous metals and high-alloy materials. We also consider human compatibility to be a very important factor: there should be no microbial growth, no foaming, and no mold growth. At the same time, the coolant must be compatible with paint and seals, while also allowing for stable processing.”

In their efforts to bring their search for the ideal coolant to an end once and for all, the experts from Blaser Swisslube and müller co-ax quite literally turned over every stone and scrutinized the manufacturing process in detail – including with respect to the materials, machining processes and machinery used. Based on this analysis and the defined requirements, Blaser Swisslube recommended the coolant B-Cool MC 660.

When coolant becomes a success factor
Jochen Rühle, Regional Sales Manager South at Blaser Swisslube Germany, sets out the benefits of the coolant used: “B-Cool MC 660 impresses with its high stability, very good lubricating performance and excellent rinsing behavior.” As a result, residue is reduced, components are kept clean, and it also allows for the reliable machining of a wide variety of materials. At the same time, the coolant is highly compatible with non-ferrous metals – especially brass, which previously posed one of the greatest challenges. “

The coolant also ensures a low tendency to mist, stable pH values, and high machine compatibility.

Measurable improvements
The positive effects were already apparent during the test phase. The machines ran smoothly, residue was reduced, and a wide variety of materials could be machined reliably. “Since starting to use B-Cool MC 660, we have not found a single thing to complain about. We were particularly impressed by the product’s stability and the fact that we no longer need to use any additives,” emphasizes Robert Christ.

And the product has had an economic impact, too. Total coolant consumption decreased by 17 percent over a period of twelve months. At the same time, we were able to extend replacement intervals and reduce disposal costs.

An equal partnership

Alongside product performance, the collaboration itself also played a pivotal role. Fatih Köksal, an Application Engineer at Blaser, regularly oversees processes at the müller co-ax site, offering his expertise in a targeted way. This ensures that the processes remain stable and the quality of the coolant remains at a consistently high level. This close relationship and technical support ensures an additional level of process security. Thorsten Müller, Managing Director of müller co-ax gmbh, emphasizes: “For us, it is essential to have a partner who understands our requirements and develops solutions together with us. In Blaser Swisslube we have found the ideal partner in this regard.”

Looking ahead

The proven performance of B-Cool MC 660 highlights the added value of Blaser’s holistic approach. müller co-ax will therefore continue to look to Blaser Swisslube’s expertise in future in order to unlock further optimization potential in its manufacturing processes.
