What is a Coolant Filtration System? Basic Knowledge You Need to Know Before Installation
Coolant is a lubricant used in machine tools. It is also called cutting oil. In addition to "lubricating" and "cleaning" effects, cutting oils also have a "cooling" effect, and since cooling is especially important in the cutting process, cutting oils are often recognized as ≒coolants. Coolant can be insoluble or water-soluble, and it is important to select the right type according to the machining process.
Coolant is generally stored in a device called a coolant tank, but foreign matter such as sludge may get mixed in as it circulates. This sludge can shorten the life of the coolant and damage workpieces and tools, so it is important to remove it as soon as possible. Coolant filtration equipment is used for this purpose.
This section introduces the types and merits of coolant filtration equipment for factories and production sites that are considering introducing such equipment. Please check the information carefully and select the equipment that best suits your company's needs to avoid the result of "I went to the trouble of installing this equipment, but it was useless..." etc.
Advantages of Coolant Filtration System
Coolant filtration equipment collects and removes chips and sludge mixed in coolant fluid. By installing this equipment, the following benefits can be obtained: "the frequency of filter replacement can be reduced," "it helps maintain high machining accuracy," and "the labor required for coolant fluid replacement and tank cleaning can be reduced.
Here, these three advantages are explained in detail. Please take the time to read through all the information, as you may find benefits that will lead to solutions to your company's problems.

Coolant filtration system type
Coolant filtration equipment comes in a wide variety of types. Here we summarize the features of filter-type filtration equipment that uses filters, centrifugal separators that use centrifugal force to separate foreign matter, and magnet-type equipment that uses the magnetic force of magnets to collect magnetic sludge and other materials.
Also, please refer to our introduction of a chip conveyor combined with a drum filter and a cyclone filter as filtration equipment suitable for cutting processes.

Can foaming of coolant fluid be improved with a filtration system?
Bubbles can occur in coolant fluid. Many people may be concerned about this problem because it is a quality-related issue. Some are considering installing filtration equipment to solve the problem, but in order to solve the problem, it is also important to understand why coolant fluid foams in the first place. Please refer to the reasons for foaming and solutions here.

Summary of coolant fluid and filtration system replacement and maintenance procedures
Coolant fluid and filtration systems need to be replaced and maintained. Unfortunately, once installed, they cannot be used forever, but it is difficult to say how often they need to be changed. This is because it depends on the frequency of use and environment of the coolant fluid. Here, we have compiled a list of maintenance methods as well as the timing of replacement for your reference.

Three recommendations
Coolant filtration equipment is used to filter sludge generated from equipment. There are a variety of products available depending on the intended use, so it is important to determine "whether the coolant filtration equipment is suitable for the purpose" and "whether the equipment is suited to the characteristics of sludge.
