CNC machining is quite common nowadays in manufacturing operations everywhere both for high production, high volume component manufacture as well as complicated small volume manufacturing where parts may have very complicated geometries and sophisticated features. During such manufacture using CNC machining processes, manufacturing engineers tend to pay very close attention to important aspects of part programming, tool choice and tool wear control, tool path control to avoid CNC tool crashes, the very important parameters of machining feeds and speeds, etc. And rightfully so, because every one of the parameters listed heretofore is very important to produce parts of the highest quality consistentlyto avoid CNC tool crashes in CNC machining

But one parameter that is seldom given its due importance is coolant control in CNC machining operations. And it is fairly easy to overlook since generally coolant is not changed after every set of parts is manufactured. Additionally, manufacturing engineers tend to delegate coolant management to maintenance personnel. However, as you will notice in what follows, that proper coolant control is important not only for part quality, but it can also influence the bottom line cost of production.

Thus it is important to ensure that coolant quality is properly maintained to produce parts with acceptable levels of surface finish and to ensure longevity of tool life in order to reduce part costs.
