With a recent trend in the shop floor towards faster machining for costs reduction, coolant is required to have a cooling capability in addition to a lubricating property. Before, water-miscible coolant, which boasts a good cooling capability, was inferior to oil-based coolant in lubricating property. However, the use of water-miscible coolant is on the rise due to its improved lubricating property achieved with additives and its lower fire risk than the oil-based type.
Water-miscible coolant is a living creature. Its deterioration causes many problems including lower cutting performance; rust on a product/machine tool; shorter tool life; unusual odor caused by decomposition; and health damage. So, many of you may find it difficult to handle and manage water-miscible coolant. Actually, we are often asked for advice about coolant handling, and there was a case where coolant in the tank foamed, which increased its volume and caused overflow into the factory floor.
