Horn’s Turbo Whirling system is designed to optimize thread whirling and increase efficiency.

The Precision Machined Products Association (PMPA) Indiana/Southern Ohio Chapter meeting on November 15 covered “All Things Threading.” The event was hosted at the Cincinnati location of PMPA technical member, Technical Equipment (a division of Morris Group Inc.), a distributor of advanced machine tools and related technology.

After a brief reception, Greg Hartman and Flawio Pelosato, from LMT-Tools (Fette) kicked off the presentations with a design overview and a practical troubleshooting review on thread rolling. Their “how to make it work” approach included discussion about how material selection and properties, blank design, tooling, feeds and speeds, and gaging all impact successful fabrication of rolled threads. They also covered new products developed for thread rolling lead-free brass.

Brian Lieving, from Horn USA, then discussed the basics of thread milling, explaining the differences between single-point and multi-point thread mills as well as the advantages over tapping. His presentation also reviewed thread whirling and compared this process to single-point threading.

The evening wrapped up with dinner in the Technical Equipment showroom, along with live demonstrations of the different threading techniques.

  • Swiss-Type Machines: More Than Just A Lathe

    CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.

  • Thread Whirling Basics

    The rapidly increasing demand for high-value threaded parts with exceptionally high length-to-diameter ratios has created a lot of interest in thread whirling technology among American shops and manufacturers.
