10 PRECAUTIONS WHEN SELECTING COOLANT
There are a variety of types of coolant available on the market.
Choose a coolant suitable for the user’s applications by consulting the supplier,
taking the following requirements into consideration.
The coolant must be free of constituents with adverse effects (smell, poison,
etc).
The coolant must not deteriorate during storage.
The coolant must not cause corrosion on the machine.
The coolant must not peel the coating off the machine.
The coolant must not cause hardening or swelling of chemical parts (rubber
parts, synthetic Resin parts, etc)
The coolant must not cause deterioration of accuracy.
Do not use highly viscous coolant. If such coolant is used, specified discharge
volume might not be obtained.
Do not use flammable coolant. Heat generated by electrical devices or during
cutting might cause a fire.
When adding water-soluble coolant, dilute the coolant first and supply diluted
coolant to the coolant tank. If only water is added to the coolant tank, it will
cause rusting of the machine.
