Oil-water Separator

Oil-water Separator

Oil-water separator is the most important environmental protection/circulation equipment in CNC machine tools.

In the machining process, a large amount of coolant (cutting fluid) is required, which will generate a large amount of wastewater and waste oil. These wastewater and waste oil will affect human health and greatly pollute the environment. Therefore, they cannot be discharged directly; they need to be separated and then treated separately. The separated water enters the water cycle for reuse, and the separated oil is treated harmlessly alone.

How does an oil-water separator work?

  • Gravity separation: Utilizing the different specific gravities of oil and water under the action of gravity to separate oil and water.
  • Air flotation separation: Making a large amount of grease or solid particles float up by generating air bubbles, and then utilizing gravity separation methods to separate them from the liquid.
  • Filtration separation: Utilizing equipment such as filters to separate solid particles through physical filtration methods.

FAQ of Oil-water Separator

Will oil-water separators affect machining accuracy?

It will not directly affect the positioning accuracy.
But it can maintain stable coolant and cutting temperature, reduce tool chip buildup, and improve surface smoothness The assistance is particularly evident for mold processing, precision parts, medical parts, and aviation components.

Does the oil-water separator need maintenance?

Many customers’ first reactiIt needs maintenance Usually only requires:
Regularly clean and collect waste oil
Clean the oil absorbing components
Check the operation of the motor
The maintenance workload is very small.

Can oil-water separators reduce skin allergies?

Many customers’Many operators have been exposed to deteriorated coolant for a long time.
Possible skin irritation, eczema, itching
Keeping the coolant clean can help improve the working environment, but it cannot completely avoid all skin problems. Proper coolant management and personal protection should still be coordinated.

Do all machine tools require an oil-water separator?

No.
If continuous production is carried out for a long time, water-based coolant is used, there is a lot of lubricating oil in the guide rail, and the hydraulic system works for a long time, we highly recommend configuring it.
If it is only occasional processing, running for a few hours a day with almost no lubricant leakage, the demand will not be so urgent

Is oil-water separator worth investing in?

For long-term production enterprises, it is usually worth it.
The reasons include:
Extend the lifespan of the coolant
Reduce the frequency of fluid change
Reduce the cost of waste liquid treatment
Improve processing stability
Reduce downtime maintenance
