Metalworking oils: keys for efficiency and performance in industry

In the heart of any machining process of a metal industry, whether it be the cutting and turning of an auto part or the manufacturing of complex components, there is a fundamental element: metalworking oil. These specialized fluids are the key for efficiency, precision, and cost-effectiveness in a wide range of operations.

What are metalworking oils?

Metalworking oils play a key role in the optimization of metal part manufacturing processes. Its main function is to reduce the friction and heat generated between the cutting tool and the workpiece. In this way, it protects tools from premature wear and also improves production quality.

You also have to bear in mind that metalworking fluids are divided into pure oils and fluids emulsifiable with water (cutting fluids). Opting for one or the other depends on the specific needs of each operation, since pure oils offer greater slipperiness, while cutting oils provide better cooling.

The selection of the right metalworking oil is a crucial aspect, since each operation has a series of specific requirements. Factors such as the type of metal being machined, the speed and depth of cut, or the geometry of the tool influence the choice of the ideal fluid. Among the properties of these lubricants, the following stand out: 

• Viscosity determines the capacity of the fluid to form an effective lubricant film.
• Cooling capacity so the heat generated during machining is efficiently dissipated.
• EP properties (Extreme Pressure) of the additives to protect the tools (i.e., that they don't chemically react and, therefore, don't cause corrosion).
• Excellent thermal stability with oxidation resistance, low volatilities, and high flash points.
• Anti-fog properties that improve visibility and safety in the work environment.

Repsol solutions for metalworking

Repsol Lubricants, aware of the complexity and demands of the metal industry, has developed various pure oil product lines for metalworking within its Maker range: Ibercut, Metal, and Laminox. They are high-performance fluids formulated with state-of-the-art bases, both synthetic and mineral, and a careful selection of additives. Thanks to this high-quality composition, they ensure superior performance and greater productivity.

They also cover a wide variety of processes, including:

• Cutting and turning. Products such as Maker Ibercut 20 APLUS (synthetic) and Maker Ibercut 20 A (mineral) offer high thermal stability and excellent oxidation resistance, ideal for operations with hard steels. For general machining, Maker Ibercut 20 C provides effective cooling and a good finish.
• Electrical discharge machining. Maker Ibercut EDM 1 and EDM 2 are formulated to cool, lubricate, and separate the micro-chips in electrical discharge machining work, ensuring precision and quality of the part.
• Grinding. Maker Ibercut 9 AM (synthetic) and Maker Ibercut 10 AMEP (mineral) facilitate the grinding of steels and alloys, preventing the formation of mists and chip welding.
• Polishing. Maker Metal 200 (mineral) and Maker Metal 300 (synthetic) are designed to polish stainless steels, ensuring an impeccable finish.
• Rolling. The Maker Laminox line offers specific solutions for the rolling of metals, ensuring optimal lubrication and high productivity.
