What is the difference between water-based cutting fluid and oil-based cutting fluid

Oil-based cutting fluid lubrication performance is better, the cooling effect is poor. Water-based cutting fluid and oil-based cutting fluid lubrication performance is relatively poor, the cooling effect is better. Slow cutting requirements of the cutting fluid lubrication is stronger, in general, cutting speed below 30m / min when using cutting oil.

Extreme pressure additives containing cutting oil, regardless of any material cutting, Suzhou cutting cutting oil when the cutting speed does not exceed 60m / min are valid. In high-speed cutting, due to heat, oil-based cutting fluid heat transfer effect is poor, will make the cutting zone temperature is too high, resulting in cutting oil smoke, fire and other phenomena, and because the workpiece temperature is too high, thermal deformation, the impact Workpiece machining accuracy, it is mostly water-based cutting fluid.
