Emuge-Franken Expands Line of Threading Tools for Safety Critical Applications

 

 

Emuge-Franken USA, a manufacturer of high-performance taps, thread mills, end mills, drills and other rotary tools, has expanded its line of Self-Lock thread locking tools. Additions to the line include Emuge ZGF-S-Cut thread mills, and Emuge high ramp precision thread gages, designed for gaging Emuge Self-Lock thread profiles.

The ZGF-S-Cut Self-Lock thread mills with helical flutes, multiple teeth and TIALN-T46 coating produce self-locking threads that are necessary in industries such as aerospace, where nickel alloys, titanium and stainless steel are commonly used. The unique design enables three tooth pitches to simultaneously rough and finish-cut threads, which is said to increase tool life and reduce cycle times. TIALN-T46 coating resists heat and wear, and further extends tool life. The thread mills are available in 16 sizes from 2-56 up to ½-20" for UNC or UNF threads, and tools starting at the ¼" size and larger feature axial coolant capability.

Emuge high ramp precision No-Go thread plug gages have also been added to the Self-Lock line. The gages are used to check the lower thread ramp point for possible ramp angle errors, and function alongside standard Emuge Self-Lock thread plug gages to verify all thread profile features.

The unique profile of Self-Lock threads allows an even distribution of stress over the entire thread length. This holding power helps functions to remain in good operation, even with repeated loosening and retightening of the thread connection. The locking effect is caused by the ramp-shaped surface integrated into the thread profile. Emuge Self-Lock technology is designed to increase threading tool life, as well as tolerance for larger thread hole diameters.
