This chip removal filter device is suitable for all kinds of special machines and machining centers that require relatively high coolant precision, and is used to separate long curling chips and filter coolant. This device is mainly composed of chain plate chip conveyor, drum filter, oil-water separator, liquid level detection device, liquid tank, fine filter, electrical control system and other modules. Its characteristics are that it can realize automatic drum cleaning, continuous filtration, high filtration accuracy, maintenance-free, no consumables, and can fully meet the filtration needs of machining centers for chip flushing, spindle internal cooling, and tool cooling. Because special machine tools and machining centers have strict requirements on chip removal, coolant accuracy, cooling pump flow and pressure, users should provide relevant technical parameters when ordering for use in design.
