Emuge-Franken USA, a leading manufacturer of high-performance taps, thread mills, end mills, drills, and other rotary tools, has announced it has expanded its line of SELF-LOCK thread locking tools to include new Emuge ZGF-S-Cut Thread Mills, in addition to Emuge High Ramp Precision Thread Gages designed for gaging Emuge Self-Lock thread profiles.

The new ZGF-S-Cut Self-Lock thread mills with helical flutes, multiple teeth and TIALN-T46 coating produce self-locking threads that are ideal in demanding industry applications such as aerospace where nickel alloys, titanium and stainless steel are the norm. A unique design enables three tooth pitches to simultaneously rough and finish-cut threads, dramatically increasing tool life and reducing cycle times.

“As the demand for self-locking threads for safety critical applications increases, our new ZGF-S-Cut SELF-LOCK thread milling products with unique geometry provide more threading options,” says Marlon Blandon, thread milling product manager, Emuge-Franken USA. "Interest in our Self-Lock threading tools, which have been successfully applied for years, continues to rise.”

The new Emuge ZGF-S-Cut self-locking thread mills have a left-hand helix flute design with left-hand spindle rotation, which greatly enhances stability and cutting performance. The first of three cutting teeth acts as a rougher, while the second and third teeth finish the full thread profile, providing perfect threads, exceptional cycle time reductions and longer tool life. TIALN-T46 coating resists heat and wear and further extends tool life. “Our ZGF-S-Cut design provides tool life which can exceed 10x that of conventional thread mills,” Blandon says. The new thread mills are available in 16 sizes from 2-56 up to ½" to 20" for UNC or UNF threads, and tools starting at the ¼" size and larger feature axial coolant capability.

New Emuge High Ramp Precision No-Go Thread Plug Gages have also been added to the Emuge Self-Lock line. The gages are used to check the lower thread ramp point for possible ramp angle errors and are used along with standard Emuge Self-Lock Thread Plug Gages to verify all thread profile features.

The special profile of Emuge Self-Lock threads allows an even distribution of stress over the entire thread length, eliminating slippage. Compared with standard threads, Emuge Self-Lock internal threads show constant, maximum holding power under dynamic stress. Functions remain in good operation even with repeated loosening and re-tightening of the thread connection. The locking effect is caused by the ramp-shaped surface integrated into the thread profile. Emuge Self-Lock technology results in increased threading tool life for larger thread hole diameters and provides larger tolerances for thread hole diameters.
