Precision control with CNC’s means we can achieve a near-identical output in product dimensions and quality. And, it also means we can create an identical problem every time the machine is used.
Case in point, the CNC shown above is used to machine a 5mm piece of aluminum, but was plagued with problems preventing it from performing to its full potential. The problem, was that when the machine would plunge into the aluminum, the plunging speed would produce excessive heat leading to a deterioration in performance and quality. The temporary solution for such a condition is to slow down the machining speeds, but this reduces the efficiency and throughput of the machine.
The real solution for this type of condition is to provide some sort of cooling for the drill head, and if possible, a means to remove the chips and debris from the machining area as well. Fortunately, both of these are possible through the use of a Cold Gun Aircoolant System.
A Cold Gun in this application will provide cold air at temperatures below freezing to cool the drill, and the airflow from the Cold Gun will simultaneously clear the small chips and debris from the machining area. And, these improvements to the application keep the workspace completely dry. There’s no need to add a coolant collection system or to create additional work through cleaning coolant from the machined pieces once they’re complete.
If you have an application in need of a dry-cooling solution, or if you’d like to explore the possibility of removing liquid cooling from your CNC, contact an EXAIR Application Engineer. We’ll be happy to help.
