Take Care
💡
Small details to prevent you from spending money in vain
- 1 Before each refueling, the oil pump, oil can and other containers and tools must be cleaned and wiped.
- 2 Before changing the oil, the machinery must be thoroughly rinsed with a solvent. Water-soluble cleaning agents must not be used.
- 3 After each addition or replacement of lubricating oil, keep a record of mechanical maintenance.
- 4 Replace the filter element at the same time as each oil change.
- 5 Keep the fuel tank sealed to prevent the entry of flying dust and moisture.
⚠️ Attention:
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 that cutting fluid mixed with miscellaneous oil can easily breed bacteria and shorten the service life.
Frequently Asked Questions (FAQ)
Q
Is this cutting fluid safe for operators and environmentally friendly?
Yes. The cutting fluid is non-toxic and harmless, fully compliant with environmental protection standards, making it safe for daily operator use and workplace environments.
Q
What concentration ratio should be used for general machining applications?
Based on typical data, a 5% concentration is standard for pH evaluation, and a 3% concentration is used for iron filings rust testing. The appropriate ratio may vary depending on your specific machining conditions — please refer to the product guidelines or consult your supplier.
Q
Can I use a regular water-soluble cleaner to rinse machinery before changing the oil?
No. Before an oil change, machinery must be thoroughly rinsed using a solvent. Water-soluble cleaning agents must not be used, as they can contaminate the new lubricating oil and affect performance.
Q
Why should I avoid mixing oil pumps for different types of fluids?
Mixing oil pumps — especially between pure oil and water-based coolant — can cause corrosion and increased wear of metal components in the lubrication system. It can also lead to bacterial growth in the cutting fluid, significantly shortening its service life.
Q
How often should the filter element be replaced?
The filter element should be replaced every time you perform an oil change. This ensures optimal filtration performance and prevents contaminants from degrading the new fluid.
Q
What is the rust prevention performance of this cutting fluid?
This cutting fluid demonstrates excellent rust prevention. In standard testing at a 3% concentration, iron filings show no rust. Additionally, its good film-forming performance provides dual effects of rust prevention and passivation on metal surfaces.
