Machining efficiency Elevating lubrication to a strategic advantage

Getting more from existing CNC equipment starts with the details of daily operation. Experience from Red Bull Ford Powertrains illustrates how lubrication can help machine shops maintain precision, reduce wear and control operating costs.

The European metal working industry is operating in an increasingly demanding environment, with energy costs, intense foreign competition and skilled labour shortages placing mounting pressure on margins. For the small and medium-sized enterprises that make up around 95 percent of the sector, major capital investment is not always an option. That is why getting more from the equipment already on the shop floor is so important.

Lubrication is one factor that is often overlooked. Frequently treated as a low-level, routine procurement decision, a plant’s lubrication strategy can have a direct bearing on machine reliability, productivity and operating costs. Looking beyond the purchase price of an oil or grease to evaluate its contribution to overall equipment performance is essential. Across high-precision sectors, from tool & mould manufacturing to medical device, automotive, aerospace and energy sector component production, machine shops are discovering that elevating lubrication to a strategic priority offers an immediate, low-capex lever to enhance asset reliability while driving down Total Cost of Ownership (TCO).

Precision under pressure

Modern manufacturers are being squeezed from all directions: machining notoriously difficult, lightweight alloys to micron-level tolerances, managing labour shortages via automated, unattended production, and navigating supply-chain volatility that makes replacement CNC parts slow and costly to source. In this high-stakes environment, an unexpected stoppage or single tiny scratch can result in reduced productivity, expensive scrap and lost contracts.

Lubrication is only one part of the maintenance equation, but it plays an important role in ensuring operational resilience. High-performance formulations can help address these challenges by controlling friction, reducing heat generation and preventing wear. A premium lubrication strategy helps extend oil drain intervals and prolong the life of cutting fluids, while supporting the longevity of expensive tooling assets.

Rather than treating lubricants as a consumable overhead, progressive operators increasingly view them as proactive risk-management tools with the potential to yield continuous dividends in terms of uptime, precision and productivity.

The ultimate stress test: lessons from the fast lane

The benefits of a premium lubrication mindset are illustrated particularly clearly in one of the most demanding, high-precision manufacturing environments in the world: Formula 1 engine construction.

At Oracle Red Bull Racing’s Red Bull Ford Powertrains facility in Milton Keynes, machine tools are regularly pushed harder than those in a typical commercial environment, both in terms of spindle speeds and round-the-clock utilisation. The team asks its equipment to perform far beyond OEM specifications, placing immense pressure on both component reliability and machining precision. When everything functions seamlessly, lubrication can easily be taken for granted. But a minor lubrication-related problem can quickly become a machine-performance issue, directly impacting asset availability, longevity and part tolerances.

The spindle represents a CNC machine’s most sensitive and valuable component, operating at extreme rotational speeds and severe thermal loads. Maintaining an effective fluid film is critical to supporting spindle performance and protecting against fatigue and wear. To protect these critical components in its 24/7 machining operation, the Red Bull Ford Powertrains team relies on Mobil Velocit spindle oils. Formulated specifically for high-speed operation, these oils help maintain the appropriate fluid film and heat management under demanding operational cycles.

Achieving micron-level accuracy depends not only on cutting tool quality, but also on the ability of the machine to make controlled, repeatable movements. Irregular actions caused by friction fluctuations known as ‘stick-slip’ can disrupt repeatability and ruin tight tolerances. Red Bull Ford Powertrains uses Mobil Vactra Oil No. 2 for slideway lubrication to ensure smooth movement and rapid separation from metal working fluids, preventing the formation of contaminated tramp oil that degrades cutting fluids and accelerates tool wear.

The broader lesson is not that standard machine shops should mirror Formula 1 production timelines or volumes. Instead, it demonstrates that the fundamentals of machining remain the same across all types of manufacturing: controlling friction, managing heat, limiting wear and maintaining repeatable movement are all essential for reliable, zero-defect production, and that teams at the pinnacle of machining precision consider lubrication an indispensable driver of operational success.

From precision to profit

The principles that enable podium-worthy precision can also deliver measurable bottom-line returns in high-volume commercial manufacturing. When seen through a TCO lens, a strategic approach to lubrication can help systematically reduce operating costs while enhancing end-product finish.

A CNC steel pipe manufacturer, for example, was able to reduce metal working fluid consumption by over 2,000 litres per year, while reducing tool costs by 57 percent through upgrading to an advanced slideway oil. Similarly, a metalworking manufacturer achieved a 400-hour reduction in its hydraulic maintenance interval, alongside substantial reductions in oil consumption, by switching to a premium hydraulic fluid. In another application, a high-throughput CNC sheet-metal operation achieved a 100 percent extension of its oil drain interval by upgrading its hydraulic fluids, effectively doubling service life and reducing labour and disposal requirements.

Ultra-fine filtration: Getting more value from coolant lubricants

These examples show why lubricant choice should be assessed in terms of its effect on the overall operation. An oil that costs less per litre is not necessarily the lower-cost option if it results in more frequent fluid changes, greater consumption, additional maintenance or shorter component life. Conversely, our experience shows that investment in a premium product can quicky pay for itself by contributing to longer service intervals, superior component protection and reduced fluid consumption.

Three ways to rethink your lubrication strategy

For European machine shops looking to adopt a more strategic, F1-inspired lubrication mindset, optimisation should focus on three key pillars: the product, the application and the process.

• The Product: Advances in lubricant formulation mean that premium products can offer performance characteristics beyond those of standard lubricants, including superior oxidation resistance and consistent viscosity across wide temperature range. In machining applications, these properties translate directly into extended oil, tool and cutting fluid life, reduced maintenance interventions, enhanced end product quality, and improved resource efficiency.

• The Application: In the IT world, a ‘Zero Trust’ architecture assumes security threats exist everywhere and extends protection to every single asset. Historically, machine shops have not used advanced lubrication solutions on a large scale, or reserved them for niche, applications. Microscopic wear and friction can reduce the effectiveness of, or damage, any machine component. Adopting a “Zero Trust” approach to lubrication means proactively deploying premium oils and greases across all high-value, heavily-loaded and critical assets. This approach also addresses the shortage of qualified maintenance staff by reducing the need for oil changes and interventions, while securing unattended production runs against machine failure.

• The Process: Even the most advanced lubricant can perform poorly if it is stored or handled incorrectly or becomes contaminated. A premium lubrication strategy means moving away from a “set-and-forget” approach in favour of clean storage, contamination control protocols, and structured oil sampling. Like a blood test, regular lubricant analysis can provide an early warning indicator, helping teams identify wear, detect contamination and initiate predictive maintenance before any failure occurs.

Making lubrication a bigger part of the picture

Poorly managed lubrication is like running outdated software: a hidden operational vulnerability that can open the door to costly unplanned downtime. Just as cyber security evolved from a back-room IT concern to a boardroom resilience priority, lubrication should be seen as a critical risk-mitigation tool.

By taking inspiration from Red Bull Ford Powertrains, commercial manufacturers would do well to shift their mindset from short-term purchase price to long-term total cost of ownership. This is not about spending more on lubricants. It is about thinking differently about them.

By selecting lubricants based on technical performance, protecting high-value assets with a ‘Zero Trust’ approach, and monitoring fluid condition proactively, commercial manufacturers can transform lubrication from an overlooked maintenance expense into a powerful driver of precision, resilience, and profitability.
