mill the cylinder to length. Asbury uses the ID to locate and fixture the part on the VF-3 machining center, and then bores and taps the bolt pattern and drills the dowel-pin holes for mating the heads and cases. Then he mounts the cylinder on the rotary-tilt table and locates the part to machine all base-locating profiles, base gasket seat, fin profiles, push-rod reliefs, all drilling opera- tions for any custom locating holes and the Delkron logo. Deburr- ing, cleaning and final inspection complete the parts for shipping. The cylinder head castings are next and undergo similar three-axis machining and profiling on the VF-3’s rotary and tilt axes. The first lot is now completed in all but one final opera- tion that finishes customization of Delkron heads. Five-axis machining of exhaust ports and combustion chambers adds considerable engine torque and horsepower. When introduced to the five-axis GibbsCAM module for pro-
gramming and machining ports and chambers, Asbury found that using it for positioning was not difficult, but for five-axis simultaneous work, the reseller provided a few hours of train-
ing. “With production demands running high, there’s no time to learn or explore the power of the software through experimenta- tion,” he said. “Under these conditions, especially with new projects coming, we’ll take any opportunity to learn the software from someone who knows it.” Jeff Gorman said that the project has been underway for
18 months, and sees completion within two more, one to complete chambers and ports, and another to machine engine cases and minor components. “After that, we have some excit- ing projects to extend the Delkron line beyond the V-Twin, into other Harley engine components,” said Gorman. “To accom- plish them, we’ll soon take delivery of another five-axis Haas VF-5. If there is excess capacity, all dependent on product demand, we’ll fill it with five-axis contract machining.” [No affiliation exists between Cometic Gasket Inc. or Delkron Manufacturing and Harley-Davidson Inc.] ME For more information from Gibbs & Associates, go to
