Function of Coolants used in Machining
Coolants used in machining serve several purposes:
Coolants provide lubrication to the cutting tool and workpiece, reducing friction and heat generated during the cutting process. This can improve tool life and surface finish.
Coolants remove heat generated during the cutting process by absorbing and dissipating it away from the cutting zone. This helps to prevent thermal damage to the tool and workpiece.
Coolants can help to flush chips away from the cutting zone, reducing the risk of tool or workpiece damage.
Coolants can provide corrosion protection for the tool and workpiece, helping to extend their lifespan.
Coolants can help to keep the machining area clean, reducing downtime for maintenance.
coolants can be formulated to biodegradable which can help to reduce environmental impacts.
The use of coolants can help to improve machining efficiency, reduce tool wear and increase surface finish, which can ultimately lead to cost savings.
Coolants can help to maintain workpiece accuracy by reducing thermal distortion and providing a stable cutting environment.
Some specialized coolants are designed for high-performance machining applications such as high-speed machining and hard turning, providing improved tool life and surface finish.
Some coolants are specially formulated to be compatible with specific types of materials, such as aluminum or titanium, to provide optimal machining results.
Health and safety:
Some coolants include biocides and fungicides to help reduce bacteria and fungal growth, which can improve the health and safety of machining operations.
Coolants can be formulated to be easy to maintain and filter, reducing downtime and maintenance costs.
