The liquid that we see in this CNC machine process is a coolant. Did you know that the purpose of a CNC machining coolant, as coolant in other applications, is to remove heat. When a cutting tool contacts a workpiece, it generates heat due to friction between the piece and the tooling. Coolant is necessary to maintain a proper operating temperature in order to prevent overheating that can lead to tool wear, poor performance, and possible equipment failure.
