Abstract: A separator that separates a lubricating oil from a coolant both of which e used in a cutting or grinding machine is disclosed. The separator comprises input, intermediate and output chambers comprising divider panels having top and bottom portions. Every other panel has a passageway near its top region and the alternate panels, relative to the every other panels, have passageways located at their bottommost region. The lubricating oil finds its way into the path of the coolant and becomes mixed therewith. The mixed lubricating oil and coolant is eventually directed into the separator. As the oil and coolant flow sequentially through the chambers of the separator, the separating properties of the oil and the coolant begin to act so that the oil raises to the surface, whereas the coolant tends to seek its way through the chambers of the separator.
