Tray Identification at the Kennametal Drill Plant
Kennametal's high quality drill bits along with their associated aluminium trays where they are arranged go through a thorough cleaning process involving ultrasound, damp and vacuum cleaning processes after machining is performed.
Before entering this washing facility, the order documents and the tray are separated and then re-allocated after cleaning. A work step that involves a risk as analyses have shown that, on occasion, trays and order documents were allocated incorrectly after cleaning. Drills went through coating processes that were supposed to be used for a different order. Hence, there was a need to eliminate mix-ups altogether.
