HERO Grinding Machine for Fuel Injection Components

The fully automated HE-grinding module is used for flow calibration of fuel injection components. Based on a round table concept the workpieces pass through the individual processes. During the HE-grinding process an abrasive fluid is pumped under high pressure through the workpiece holes to round them. The flow increases, depending on the application, from 5% to 20%.The grinding process is stopped as soon as the correlated target flow has been reached. In front of the round table there is a robot loader with drawers to insert the workpieces on pallets into the machine. After turning the workpiece with a turn unit, the robot moves the
workpieces in front of the camera to read the Dot Code on the part. A second camera checks the orientation of the part to put the workpiece orientated into the round table nest. The round table includes three grinding, three flushing and three measuring nests
to work on three different workpiece holes in one turn on the table. After finished processing in the turntable the robot moves the workpieces back to the outtake pallets in the drawers.
