Reduce chip contamination from double end finishing operation.
Solution: Haven designs and builds some of the most advanced process solutions in the tubing industry. But even the best solutions may have an inherent characteristic that may not satisfy certain customer specifications. In this case study, a leading automotive parts supplier required a chip removal operation to be integrated with the double end finishing operation. To find a solution, we examine Haven’s double end finishing process, which consists of I.D. / O.D. chamfers and end facing. As with all Haven end finishers, close and repeatable tolerance control is a standard, along with maximum cycle rates for the application. Standard Haven end finishers are designed to release the tube after the machining operation and escape out the front of the machine. This sequence loses control of the tube, not allowing us to perform sequential operations within the frame of the machine. For this application, in order to gain control of the tube, we designed a simple and economical shuttle beam transfer system into the part indexing sequence. The shuttle performs three required tasks. First, the shuttle passes below a stack of tubes that have accumulated in the magazine rack. One tube is stripped from the bottom of the rack and transferred to the working station. As the shuttle is filling the working station, it is simultaneously removing a part and indexing it to the chip removal station, while a chip free tube is indexed out of the machine and down an exit ramp. The shuttle motion is continuous as long as parts are available and proximity switches have verified that parts are present and that the machining and chip removal operations have been completed.

Results: Haven has the ability to adapt to most any customer specification. Our design knowledge, flexibility, and manufacturing experience lead us to a customer satisfied solution.
