Sewtec automation had 6 CNC machines and got 140 hours of machining time from them. Lot of time was spent in set ups.
They shifted to HAAS Vertical machining centres with HAAs WIPS system Now there are 11 machines and they are getting 1180 hours of machining time.
While machines increased only by 80%, machining time increased by 850%.
