MACHINE CAPABILITY The machine tool coolant path (spindle seals, rotary unions, hose, fittings, etc.) must be suitable for the pressure applied. The machine components must have a working pressure rating equal to or greater than the maximum coolant pressure supplied. MACHINE ENCLOSURE Higher pressure at the tool along with faster metal removal rates may produce more splash and coolant atomization (mist) depending on the machining process. FILTRATION Most spindle OEM’s recommend that coolant should be filtered to between 10 and 30 microns for proper operation of their systems. This higher filtration also improves part finish and tool holder to spindle accuracy (less contamination). Most machine tool manufacturers provide a ‘police filter’ in the coolant path, near the machine tool spindle. This filter functions as a back-up filter downstream of the main filters to insure against stray contamination from the coolant hoses, fitting sealant, improper filter media in the main filters and etc. Such a filter usually has a nominal filtration level significantly higher (less filtration) than the main coolant filters. As such, it should not require attention except during periodic system cleaning. It is recommended to insure the machine is equipped with such a filter. |
