Frequently Asked Questions
Q
What does EP property mean in cutting oil, and why does it matter?
EP stands for Extreme Pressure. EP additives form a protective film on metal surfaces under high-load cutting conditions, reducing friction and wear. This directly prolongs tool life and helps achieve a superior surface finish on machined parts.
Q
Is this cutting oil safe to use on copper and copper alloy workpieces?
Yes. This product uses in-active sulphur technology, which means it will not react with or stain cuprous metals such as copper and brass. You can switch between ferrous and non-ferrous workpieces without needing to change the cutting oil.
Q
What is the recommended operating viscosity for this cutting oil?
The typical kinematic viscosity is 11.9 CSt at 40℃, making it suitable for a wide range of heavy-duty cutting and machining operations where good lubrication film strength and flow are both required.
Q
How does the anti-rust property benefit the machining process?
The built-in anti-rust additives form a protective layer on machined surfaces after cutting, preventing oxidation and rust formation during storage or between production stages. This reduces the need for additional rust-prevention treatments and lowers overall scrap rates.
Q
Why is the clear pale colour of the cutting oil an advantage?
A clear, pale yellow transparent appearance allows operators to easily monitor the cutting zone, inspect workpiece surfaces, and detect any abnormalities during machining. It also makes it easier to assess the condition and cleanliness of the oil during use.
Q
What industries and applications is Depa's cutting oil suitable for?
Depa's metalworking fluids are designed for a broad range of industries including military, aviation, medical, semiconductor, automotive, electronics, papermaking, and general machinery manufacturing. Custom formulations are also available to meet specific process requirements.
