Mineral based neat cutting and grinding oils

Essential for the proper functioning of machine tools, these fluids are designed to improve cutting performance, reduce tool wear and ensure a high quality surface finish. In this in-depth look, we will explore in detail what mineral-based neat cutting oils are, how they are used in machine shops, the benefits they offer, and answer some of the most frequently asked questions on this topic.

What are neat cutting oils with mineral bases?

Mineral-based neat cutting oils are lubricating fluids used in metalworking processes. Unlike emulsifiable oils, which are mixed with water, whole oils are used in their pure form. The mineral base of these oils is derived from petroleum, and their formulation is enriched with specific additives that enhance lubricating and cooling properties.

These oils are designed to withstand the high temperatures and pressures generated during cutting operations, such as turning, milling, drilling and grinding. Their main function is to reduce friction between the tool and workpiece, thus minimising tool wear and improving the quality of the machined surface.

Use of mineral-based neat cutting oils in machine shops

In machine shops, neat cutting oils with mineral bases are used in a wide range of applications. The choice of the right oil depends on several factors, including the type of material to be machined, the type of cutting operation and the specific requirements of the machine tool.

For example, for machining ferrous materials, oils with high anti-wear and antioxidant properties are preferred, while for non-ferrous metals, such as aluminium and copper, oils with additives that prevent staining and corrosion are used. In addition, the viscosity of the oil is a critical factor to consider, as it affects the oil's ability to penetrate the cutting point and provide effective lubrication.

Advantages of mineral-based neat cutting oils

The use of mineral-based neat cutting oils offers numerous advantages in machining operations. Among the main benefits, we can highlight:

1. Improved tool life: whole oils reduce friction and heat generated during cutting, prolonging tool life and reducing replacement costs.

2. Quality surface finish: Due to their ability to reduce friction, these oils contribute to high quality machined surfaces with a smooth, flawless finish.

3. Operating efficiency: The use of mineral-based neat cutting oils can improve the efficiency of cutting operations, allowing higher machining speeds and reducing cycle times.

4. Corrosion protection: Additives in whole oils offer effective protection against corrosion, preserving the integrity of machined parts and machine tools.

5. Safety and health: Mineral-based machining oils are formulated to be safe for operators, with low smoke and odour emissions, contributing to a healthier working environment.

Frequently asked questions about mineral-based neat cutting oils

1. What is the difference between whole oils and emulsifiable oils?

Whole oils are used in their pure form, while emulsifiable oils are mixed with water to form an emulsion. Whole oils offer superior lubrication and are ideal for heavy cutting operations, while emulsifiable oils are more economical and suitable for less demanding operations.

2. How do I choose the right neat cutting oil?

Choosing the right oil depends on the material to be machined, the type of cutting operation and the specifications of the machine tool. It is important to consult the product data sheets and, if necessary, seek the support of an expert to select the most suitable oil for your needs.

3. Are mineral-based neat cutting oils environmentally friendly?

Although mineral oils are derived from petroleum, many manufacturers are developing more environmentally friendly formulations with biodegradable and environmentally friendly additives. It is important to choose products that comply with environmental regulations and are properly managed to minimise their impact on the environment.

4. What precautions should be taken when using neat cutting oils?

It is essential to follow the manufacturer's instructions for the use and handling of whole oils. Operators should wear appropriate personal protective equipment and ensure adequate ventilation in the work area to reduce exposure to fumes.

5. How should used neat cutting oils be disposed of?

Used oils must be collected and disposed of according to local hazardous waste regulations. It is important to work with companies that specialise in the treatment and disposal of oils to ensure safe and legally compliant handling.

In conclusion, mineral-based neat cutting oils are an essential component for machine shops, offering superior performance and helping to improve the efficiency and quality of machining operations. Choosing the right product and handling it correctly are key to maximising the benefits and ensuring a safe and sustainable working environment.
