Take Care
Small details that prevent you from wasting money unnecessarily
- Each type of machinery is marked with a simple diagram indicating the parts that need to be refueled, the name of the oil product, the refueling cycle, etc., and is managed by a dedicated person to avoid using the wrong oil product.
- Use dedicated containers for each type of oil, and label the container with the name of the oil to prevent contamination.
- After each addition or replacement of lubricating oil, keep a mechanical maintenance record.
- Rust inhibitor must be added to the cooling water circulation system of the injection molding machine to prevent the formation of scale, which can cause corrosion and leakage of the heat exchanger into the hydraulic system.
- Keep the fuel tank sealed to prevent the entry of dust and moisture.
⚠️
Attention must be paid to using specialized oil pumps for various types, especially for pure oil and water-based coolant. Mixing oil pumps is extremely avoided, as it may cause corrosion and increased wear of metal parts in the equipment lubrication system. It is also possible to mix cutting fluid with miscellaneous oil, which can easily breed bacteria and shorten the service life.
Frequently Asked Questions
Q
What makes this cutting oil suitable for heavy duty machining of ferrous metals?
This cutting oil is formulated with strong EP (extreme pressure) additives and superior lubricity agents, enabling it to withstand the high pressures and temperatures generated during heavy duty cutting of high hardness ferrous metals. This helps reduce tool wear and improve surface finish quality.
Q
How does the anti-rust property work after machining is complete?
The oil contains corrosion inhibitors that form a protective film on machined metal surfaces. This film remains effective even after the machining process ends, shielding parts from moisture and oxidation during storage or transit.
Q
Why is it important to use dedicated oil containers and pumps for each oil type?
Cross-contamination between different oil types — especially between pure cutting oil and water-based coolants — can degrade performance, promote bacterial growth, and accelerate corrosion and wear in the lubrication system. Dedicated containers and pumps eliminate this risk entirely.
Q
What viscosity grade is this oil and what does it mean for my application?
The oil has a kinematic viscosity of 17.8 CSt at 40℃, which places it in a light-to-medium viscosity range. This makes it well-suited for high-speed cutting operations where good flow and heat dissipation are needed without sacrificing lubrication film strength.
Q
Why should rust inhibitor be added to the cooling water system of injection molding machines?
Without rust inhibitor, scale and corrosion can develop inside the heat exchanger. If the heat exchanger leaks, water can enter the hydraulic system, causing serious damage to hydraulic components and significantly reducing equipment service life.
Q
What is the significance of the open flash point being ≥180℃?
A flash point of ≥180℃ indicates that the oil has a high ignition threshold, making it significantly safer to use in high-temperature machining environments. It reduces fire risk during heavy duty cutting operations and complies with standard industrial safety requirements for metalworking fluids.
