There are various types of metal working fluids available in the market. The first one is the straight oil which is composed of mineral, animal and vegetable oils. The second type is known as soluble oil that is composed of petroleum oils and emulsifiers. The third type is known as the semi synthetic fluids which combine petroleum oils and water. The last type is known as the synthetic fluids, which are made up of detergent like additives.
