HOCHDRUCKANLAGE FÜR WERKZEUGMASCHINEN

摘要

A coolant system (10) is disclosed for use with a machine tool (102) in which coolant (22) is used to both cool and lubricate a workpiece (72) and cutting tool (76). The system (10) of the present invention utilizes a positive displacement pump (14) with one or more spray nozzles (36) each having a restricted orifice whereby the coolant (22) is sprayed from the nozzles (36) at a relatively high velocity and pressure enabling the coolant (22) to be precisely directed to the cutting location to provide optimum cooling and lubricating of the workpiece (72) and cutting tool (76). Check valves (40,42) are provided for both the pump inlet (16) and outlet (24) lines to maintain the pump (14) in a primed condition and prevent drainage of coolant (22) from the coolant system (10) when the pump (14) is not operating. The system filter (40) is mounted to a flexible coolant line (18) to enable the filter (40) to be raised from the coolant reservoir (12) and the filter (40) is coupled to the coolant line (18) by a quick connect/disconnect coupler (60) to enable the filter (40) to be raised from the reservoir (12) and quickly replaced with a clean filter (40) when the first filter (40) becomes clogged and requires cleaning.
