A shortened toolpath process produces internal threads in less than half a second to reduce energy consumption and threading time. The punch tap is made from an HSSE-PM alloy opti- mized for toughness and long wear. Its teeth geometry is said to produce threads in a single step. It also fea- tures two rows of flutes, offset 180 degrees from each other and extending in a helical curve down to a usable application depth. This speeds threading by reducing toolpath length. The tool punches into a pre-drilled hole and the first tooth of each flute produces a helical groove, which guides the tap to the application depth. Threading com- mences by cold forming with a synchronous movement of feed and rotation. The thread is produced with a half left turn in the pitch, and each tooth produces half a thread (approximately 180 degrees). After the threads have been formed, the tool retracts from the hole in a helical motion. The finished, cold-formed thread is inter- rupted by two helical grooves offset by 180 degrees. Thread strength is comparable to conventionally machined threads from a depth of thread of 3×D, according to the company. The tool is custom-designed for coatings and dimensions according to application requirements. | Emuge Corp. | West, Level 3 & Annex, Booth 431536
