3D Printing’s Value in a Production Turning Environment

Superior Metal Products in Omaha, Nebraska, has designed a unique plug it 3D-prints to prevent chips and coolant from shooting back through the tube and into the bar feeder while turning DOM tubing. “We struggled to find a solution that offered push-point consistency for the bar feeder and positive sealing for the various tube IDs we run,” explains Frank O’Connor, company president. “Tapered plugs tend to dislodge and leak, and care must be taken to ensure the plug end is perpendicular to the tube. Otherwise, push rod droop or tube orientation can cause push length variation.” 

The plug features a 3D-printed ABS threaded knob, expander and nut (all are printed at the same time), as well as an appropriately sized O-ring. Once inserted into the end of a bar and tightened, it provides an effective seal and consistent push point that is perpendicular to the tube. The shop has a base plug design and simply modifies the sealing diameters depending on the tube ID and prints. It’s not a problem if a plug gets lost. 3D printing replacements is not costly. 

The three main plug components are printed at the same time

The shop uses quick-change toolholder system for fast tool changes on its twin-spindle turning centers and 3D-prints trays to hold fresh tools for the 10-station-turret machines

The shop also uses its 3D printer, a Lulzbot TAZ-6 desktop model, to create toolholder trays and other items to support its 5S workplace organization efforts. For example, hanging on the fence of a robot-tended machining cell for pump components are printed items to hold Allen wrenches, a broom, a dust pan, a cleaning bottle, a grease gun, job travelers and so on. The shop also prints job-specific trays for gages and other devices.
