✦ Take Care
⚠️
Small details that prevent you from wasting money unnecessarily
- 1 Consult with lubrication experts, use lubricants of appropriate specifications, and minimize the types of oil used.
- 2 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.
- 3 Before each refueling, clean and wipe containers and tools such as oil pumps and oil pots.
- 4 Use dedicated containers for each type of oil, and label the container with the name of the oil to prevent contamination.
- 5 Before changing the oil, the machinery must be washed clean with solvent, and water-soluble cleaning agents must not be used.
✦ Frequently Asked Questions
Q What dilution ratio should I use for general machining operations?
For general machining, a dilution ratio of 5% is recommended. For light cutting and grinding, 3–5% is sufficient, while medium to heavy load cutting requires 7–10%, and heavy load cutting may need up to 10–20%.
Q Is this cutting fluid safe for the environment and operators?
Yes. This cutting fluid is formulated without sulfur or phosphorus, making it less harmful to both the environment and human health compared to conventional cutting fluids containing these additives.
Q How does this fluid help protect machined surfaces from rust?
The fluid contains dedicated anti-rust additives that form a protective film on metal surfaces during and after machining, effectively inhibiting oxidation and corrosion even in humid workshop environments.
Q Can this cutting fluid be used across different types of materials and operations?
Yes. This is a multifunction cutting fluid designed for a wide range of operations and materials, including turning, milling, drilling, and grinding on ferrous and non-ferrous metals.
Q How should I prepare the machine before changing to this cutting fluid?
Before changing the oil, thoroughly clean the machine with an appropriate solvent to remove residual old fluid. Do not use water-soluble cleaning agents, as they may leave residues that interfere with the new fluid's performance.
Q What is the pH value of the emulsion and why does it matter?
At a 5% concentration, the emulsion has a pH value of 8.5, which is mildly alkaline. This range is optimal for inhibiting bacterial growth, protecting metal surfaces from corrosion, and ensuring operator skin safety during prolonged use.
