Coolant delivery systems are devices or systems used in manufacturing processes to provide a continuous supply of coolant to a cutting tool or workpiece. The coolant helps to reduce heat generated by the cutting process, prolong the life of the tool, and improve surface finish. Coolant delivery systems can take different forms, including coolant-through tooling, flood coolant systems, high-pressure coolant systems, or mist coolant systems. The choice of coolant delivery system will depend on the specific application and the type of material being machined.
