Straight Oil, High Performance Neat Oil

In CNC machining, the choice of cutting oil plays a crucial role in determining the efficiency and quality of the operation. Oil-based cutting oils, composed of base oils and water-insoluble additives such as rust inhibitors and lubricants, are essential for a wide range of machining applications. Unlike water-soluble cutting fluids, these oils are used directly without dilution, making them suitable for various machining operations, from light to heavy-duty tasks.

Whether it's gear cutting, broaching, turning, or drilling, oil-based cutting oils are widely utilized across industries, including hardware components, bicycles, and automotive parts. Their ability to offer superior lubrication and rust protection makes them indispensable for achieving high precision and extended tool life.


Neat cutting oil is used in a variety of machining operations which are generally blends of mineral oils and other additives and used for cutting without further dilution i.e. as supplied by the manufacturer.

Neat cutting oil (straight oil) can be used for applications from light machining to heavy-duty operations such as gear hobbing, broaching, turning, honing, and drilling that help increase productivity and performance, and meet your machining needs.

Neat cutting oils also save energy by reducing cutting forces which as opposed to soluble or synthetic cutting fluids provide cooling and lubrication that lead to good tool life and appropriate surface finish of the components.

Hai Lu Jya He, we offer MORESCO NA series and MORESCO NN series which have been designed to increase productivity and performance, as well as maintain high surface-finish levels and dimensional accuracy. MORESCO series are suitable for a wide range of applications that provide excellent lubrication, reducing friction between cutting tools and workpieces. This leads to decreased tool wear, extended tool life, and improved machining precision.

Apart from that, we also offer tailor-made products (OEM/ODM) - OEM/ODM services ensure that lubricants are custom-engineered to align perfectly with machine design, enabling enhanced precision, accuracy, and surface finish.

The Advantages of Neat Cutting Oils in CNC Machining

Neat cutting oils, also known as straight oils, are a type of lubricating oil used specifically in metal machining operations. Unlike water-miscible cutting fluids, neat cutting oils are applied directly to the machining process without any need for water dilution. These oils are generally blends of mineral oils and other additives, making them suitable for a variety of machining tasks.

From light machining to heavy-duty operations like gear hobbing, broaching, turning, honing, and drilling, neat cutting oils help increase productivity and performance while meeting the demanding needs of modern machining.

One of the key benefits of neat cutting oils is their ability to save energy by reducing cutting forces. This is especially important when compared to soluble or synthetic cutting fluids, as neat oils provide both cooling and lubrication, leading to extended tool life and an improved surface finish of the machined components. By minimizing friction between cutting tools and workpieces, neat cutting oils not only reduce tool wear but also enhance machining precision, making them a preferred choice for industries requiring high levels of accuracy and surface finish.

Selecting the Right Oil-Based Cutting Oil for Optimal Machining

Choosing the appropriate oil-based cutting oil is crucial for maximizing machining efficiency and achieving optimal results. Compared to water-soluble cutting oils, oil-based cutting oils offer superior lubrication and rust protection, making them particularly well-suited for precision machining tasks. However, it's essential to consider the differences in application when working with ferrous and non-ferrous metals.

Hai Lu Jya He offers a comprehensive range of MORESCO oil-based cutting oils, specifically designed to cater to different machining needs. The MORESCO NN series, which contains inactive sulfur, is ideal for cutting non-ferrous metals such as aluminum, brass, and copper.

On the other hand, the MORESCO NA series, with active sulfur additives, is formulated for cutting ferrous metals like carbon steel and stainless steel. For instance, the MORESCO NA-308T oil-based cutting oil performs exceptionally well in both high and low-speed machining operations, making it a versatile solution for various industrial applications.

Customized Oil-Based Cutting Oils for Enhanced Machining Efficiency

Recognizing that different machining operations require tailored solutions, Hai Lu Jya He provides customized oil-based cutting oils designed to meet specific needs. Our MORESCO oil-based cutting oils are not only formulated to offer exceptional lubrication and rust prevention but can also be customized to match the exact requirements of your machining process. This ensures optimal performance, whether you are working with ferrous or non-ferrous metals.

The non-sulfurized (NN series) oils are particularly suited for non-ferrous metal cutting, while the sulfurized (NA series) oils are designed for ferrous metal cutting, addressing the unique demands of each material. This level of customization helps in achieving the best possible machining results, ensuring that your operations are both efficient and cost-effective.

At Hai Lu Jya He, we are committed to delivering high-efficiency, stable cutting oil products that not only meet but exceed industry standards. Our products are backed by comprehensive oil consultation and after-sales services, including CNC cutting oils, equipment lubricants, and waste lubricant recycling. We also offer OEM/ODM services, ensuring that lubricants are custom-engineered to align perfectly with machine design, enabling enhanced precision, accuracy, and surface finish.

If you are ready to elevate your machining performance, Hai Lu Jya He is here to help. Contact us today to discuss your requirements, or place an order. Our team of experts is dedicated to assisting you in finding the perfect cutting oil solution tailored to your needs.
