I’ve been unhappy with the splashing of coolant from PCNC770 onto the floor but I didn’t want to add a full enclosure as others have done. Also the original single coolant nozzle didn’t wash away the chips depending on the angle of the cut path. I added a coolant manifold (the upper blue U in the photos) to pipe coolant to up to three nozzles (only two currently installed). Flow to each nozzle is controlled by a ball valve. The lower blue U supports a “hula skirt” of vinyl that catches much of the splashing. The skirt can be raised/lowered and secured with half-cotters on the stainless rods to accommodate various lengths of tooling. The skirt’s “belt” (crescent moon shaped unpainted aluminum with red layout dye in the photos) is attached by rare earth magnets and is aligned on Delrin® posts so it can be easily removed for tool changes or when cutting dry.
In all, it seems to be a significant improvement.
