Abstract: A coolant filtration system and method for use with one or more metal working machines. The system includes a housing, pump, conveyer assembly, drum assembly, and centrifugal separator. The housing includes a tank that receives and holds coolant coming out of the one or more metal working machines. The pump is used to drive the coolant through the coolant filtration system. A part of the conveyer assembly is disposed within the housing in order to carry-away workpiece chips from the coolant. The drum assembly is located near the conveyer assembly in order to filter the coolant. The centrifugal separator receives coolant processed by the conveyor and drum assemblies. The system can further include one or more fine filters for additional filtering of the coolant outputted by the centrifugal separator.
