What is the purpose of using coolant in machining processes?

Using coolant in machining processes primarily serves to improve lubrication and manage heat. During machining, friction between the cutting tool and workpiece generates significant heat, which can lead to thermal deformation, reduced tool life, and poor surface finish. Coolants help mitigate these issues by providing a lubricant that reduces friction, thereby enabling smoother cutting operations and preventing overheating. The use of coolant not only prolongs the lifespan of the cutting tool but also helps maintain dimensional accuracy and surface integrity of the machined parts.

In addition, effective cooling can facilitate faster machining rates by allowing higher speeds and feeds, which is particularly beneficial in high-volume production environments where efficiency is crucial. Overall, the strategic application of coolant is essential for optimizing performance, ensuring safety, and achieving high-quality results in machining operations.
