Coolant System Service The coolant system consists of a fluid tank pump and flexible nozzle The pump pulls fluid from the tank and sends it to the valve which controls the flow of coolant to the nozzle As the fluid leaves the work area it drains back into the tank through the chip drawer and catch tray where the swarf is screened out Use Figures 110 111 to identify the locations of the coolant system controls and components Nozzle amp Valve Lever Coolant Pump Switch Catch T Chip Drawer Pump amp Reservoir Inside Cabinet Figure 111 Additional coolant components Although most swarf from machining operations is screened out of the coolant before it returns to the tank small particles will accumulate in the bottom of the tank in the form of sludge To prevent this sludge from being pulled into the pump and damaging it the pump s suction tube is positioned a couple inches from the bottom of the tank and fitted with a fine screen This works well when the tank is regularly cleaned however if too much sludge is allowed to accumulate before the tank is cleaned the pump will inevitably begin sucking it up Hazards As coolant ages and gets used dangerous microbes can proliferate and create a biological hazard The risk of exposure to this hazard can be greatly reduced by replacing the old fluid on a monthly basis or as indicated by the fluid manufacturer The important thing to keep in
