Emulsion Types
Cutting fluid (Emulsion) is a type of coolant and lubricant designed specifically for metal working processes. There are
various kinds of cutting fluids. They may be made from petroleum distillates, plant oil, water and air, or other raw ingredients.
Most metalworking and machining processes can benefit from the use of cutting fluid, depending on work-piece material.
Common exceptions to this are cast iron and brass , which are machined dry.
There are generally three types of liquids:
• Mineral emulsion
• Semi-Synthetic emulsion
• Synthetic emulsion
Semi-synthetic and synthetic cutting fluids represent attempts to combine the best properties of oil with the best properties
of water by suspending emulsified oil in a water base. These properties include: rust inhibition, tolerance of a wide range of
water hardness ,ability to work with many metals, resist thermal breakdown, and environmental safety. Water is a good
conductor of heat but has drawbacks as a cutting fluid. It boils easily, promotes rusting of machine parts, and does not
lubricate well. Therefore, other ingredients are necessary to create an optimal cutting fluid.
The CoolSpeed mini may use each type of emulsion to drive the turbine.
For calculating turbine rotation speed, we assume 95% water (viscosity and density).
