EMUGE-FRANKEN USA, manufacturer of high-performance taps, thread mills, end mills, drills, and other rotary tools, has expanded its line of Self-Lock thread locking tools with the 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 for demanding industry applications, such as aerospace parts where nickel alloys, titanium and stainless steel are the norm. The 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,” said 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 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 10 times that of conventional thread mills,” Blandon said. The new thread mills are available in 16 sizes from 2-56 up to ½-20 inches for UNC or UNF threads, and tools starting at the ¼-inch size and larger feature axial coolant capability.
New Emuge High Ramp precision no-go thread plug gages also have 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.
