Machining Coolant Centrifuge

Many companies do not continually measure the contamination levels in their machining coolants. They have learned by trial and error that by changing the coolant once a month or so, no problems will occur in the following machining stages. Changing coolants just because they are dirty is an old-fashioned approach. It is also a messy and time-consuming task. With an industrial fluid centrifuge, you can control the amount of contaminants in the tank. A machining coolant centrifuge effectively removes tramp-oil and sediment (down to 0.5µ) from the coolant in a single operation on a continuous basis.

Advantages of a coolant centrifuge:

  • Savings: Centrifuge allows re-use of machining coolant.
  • Disposal: Recycling reduces disposal costs considerably.
  • Quality: Cleaner coolant leads to higher quality finished products.
  • Reliability: Contaminant removal leads to the durability of process equipment.
  • Health: Reduces bacterial contamination, which can cause health issues.

In summary, an industrial fluid centrifuge offers several advantages, especially for larger-scale handling of cutting fluids.

Tramp Oil Centrifuge

A tramp oil centrifuge is an industrial, 3-phase centrifuge designed to separate tramp oil from water-based coolants. A high-speed, disc-stack centrifuge produces over 7,800 g’s to continuously separate the tramp oil and solid particles from the machining coolant.

Industrial coolant gets contaminated with oil from the machining of oil-coated components and parts. This oil is known as tramp oil and if not removed, it degrades the performance of machine coolants.

Tramp oil floats on top of the water-based coolant, which causes anaerobic bacteria to grow. This bacterial growth is the cause of health issues for machine operators.

Have you heard of pasteurizing machining coolant? It helps eliminate the bacteria in coolants. Read our detailed article about machining coolant recovery using a disc centrifuge and pasteurization.

Centrifuges for Drawing Oil and Rolling Oil

A wide variety of industrial applications, like gear cutting, lubrication, and cooling, use oils. Oil also transmits mechanical energy in hydraulics. Alfa Laval industrial fluids centrifuge separates metal contaminants from Cutting Oil and Wire Drawing Oil. An industrial centrifuge is ideal for separating fine metal particles from mineral oils or coolant. The machining industry, including milling, rolling, and other general machining operations, use these oils.

Oils are expensive to buy and sometimes are even more costly to dispose of. Environmental regulations are becoming demanding, with laws banning the “wear-out and throw-away” approach. In other words, companies today must keep their oils in service for as long as possible. With an industrial fluid centrifuge, they can – sometimes indefinitely!

The industrial oil centrifuge removes particles and water from cutting oil. This process is 3 phase separation (liquid/liquid and solids). Having clean oils all the time means significant savings in many ways. These include

  • Reduced purchasing and disposal costs for oils and filter cartridges.
  • More production up-time.
  • Reduced wear and corrosion on the equipment served.

The pay-off time for a separator is thus short, and often less than one year.
