For those who have through tool coolant delivery systems on their CNC machines, keeping the coolant pins clean and functioning, and replacing them as needed should be part of your planned preventative maintenance program. However, some shops forget about these small items and the result can be costly.
Among the technology trends discussed at IMTS 2012 is the growing necessity for high-pressure coolant delivery to enable CNC machine tools to efficiently tackle difficult-to-machine materials such as titanium and various exotic alloys. Manufacturers spend millions of dollars on liquid coolants each year. In many cases the benefit of this coolant could be greatly enhanced – in some applications by 100% or more – by using a high-pressure coolant delivery system.
