Frequently Asked Questions
Q
What makes this cutting oil effective at improving surface finishing?
This cutting oil provides excellent lubrication between the tool and workpiece, significantly reducing friction and heat generation during machining. Lower heat means less thermal deformation, resulting in a smoother, more precise surface finish.
Q
How does this oil help prolong tool life?
By reducing heat and friction at the cutting edge, the oil minimizes wear on the tool. The special additives also provide a protective film that prevents metal-to-metal contact, extending the service life of cutting tools considerably.
Q
What do the Four-ball test values (PB 100 KG / PD 440 KG) indicate?
The Four-ball test measures extreme pressure (EP) performance. PB (load-wear index) of 100 KG indicates the oil's ability to prevent welding under load, while PD (weld point) of 440 KG shows the maximum load the oil film can withstand before metal surfaces weld together — both values reflect strong EP protection.
Q
What is the significance of the viscosity value of 25.76 CSt at 40℃?
A viscosity of 25.76 CSt at 40℃ places this oil in a medium-light viscosity range, making it suitable for general-purpose cutting and grinding operations. It flows well enough to reach the cutting zone efficiently while maintaining a sufficient lubricating film.
Q
How is this cutting oil removed after machining?
The oil is designed for easy removal using standard detergent cleaners or solvent-based cleaners, simplifying post-machining cleaning of both workpieces and equipment without requiring specialized cleaning agents.
Q
Does this oil offer rust and oxidation protection for machined parts?
Yes. The special additives formulated into this oil enhance both oxidation stability and rust prevention properties, helping to protect machined metal surfaces and the oil itself from degradation during storage and use.
