Changing the coolant: How to correctly renew the coolant in machine tools.

Correct replacement of coolant is a key step in ensuring smooth operation of machine tools. Timely replacement not only determines the quality of machining, but also the longevity of the equipment.

Coolant is a complex of surfactants with multicomponent additives, including antibacterial and anticorrosive ones.
By classification Coolants can be water-miscible and non-water-miscible. Regardless of the type of coolant, the spent working solution, depending on contamination, needs to be changed in time.

When coolant needs to be changed in machines:

• Mechanical pollution and bottom sediments (ingress of chips, scale, rusty fragments from dirty parts, foreign liquids and oils).< /li>

The consequences of such contamination are the appearance of corrosion and / or sticky deposits on equipment and parts.

• Bacterial damage to the working solution (occurs when the permissible concentration of the working solution is underestimated, during long-term downtime of the equipment, when using water from a well or a well).

In case of bacterial damage, the working solution changes its color to dark gray, and a sharp unpleasant odor appears. Service personnel can often experience skin irritation.

In case of the above problems, it is urgent to replace the working solution in the machine.

How to change coolant correctly

The coolant replacement process involves several steps:

1. Draining the used coolant: completely remove the old coolant from the tank, clean the bottom sediments.
2. Cleaning the tank: thoroughly wipe the internal surfaces with a dry cloth.
3. System flushing: prepare a 3% solution by mixing 1 part of Biol Eco with 30 parts of water. Pour it into the system and let it circulate for 2-6 hours.
4. Drain the flushing liquid: after circulation, drain the solution, wipe the container dry again.
5. Filling in new coolant: prepare a fresh solution (for water-mixing coolants) or use ready-to-use fluid.

Recommendations for changing and preparing the working coolant solution

1. Use special containers: the solution should be prepared in a separate, dedicated container.
2. Designate a person to be in charge: one person should supervise the replacement and preparation of the solution.
3. Use filtration equipment: this prevents chips and other contaminants from entering the system.
