Tooling Program for Threading Titanium Alloys

Emuge Corp. is introducing a comprehensive line of high-performance tools for threading demanding alloyed titanium materials. Ranging from taps with new geometry designs to solid carbide thread mills, the program offers products engineered for demanding titanium challenges such as those found in aerospace, defense and medical machining applications. A full line of tap sizes from no. 0 to 1" are available in UNC, UNF and from 3 x 0.5 to 24 x 3.0 in metric, 222 tools in total.

The Emuge Titanium Program features C-Ti and D-Ti taps with new High Relief Geometry (HRG) technology, which is designed to increase space between the friction surfaces for enhanced lubrication and reduced torque load in both forward and reverse direction. "HRG counteracts the high compressive forces produced by the extreme elastic memory of titanium," said a company spokesperson. "An optimized flute angle and profile create tough, long chips that evacuate axially in one direction. Taps are manufactured with premium HSS-E steel for exceptional heat and wear resistance, and a modified bottoming chamfer provides reduced torque and increased tool life."

With advanced left-hand helical flute form and chamfer geometry, C-Ti taps are designed to optimize chip evacuation in the forward direction and add strength to the cutting teeth for enhanced tool life and process security. The new D-Ti taps are available in STI thread sizes for jet engine components. Both C-Ti and D-Ti taps are available in an NT2 coating with nitriding that provides increased edge hardness and a steam layer over the nitriding that promotes lubricity to prevent cold welding. Taps are also available with a TiCN multi-layer PVD coating for increased edge hardness and surface lubricity.

The Titanium Program also offers a variety of thread mills. "THREADS-ALL Z-GF style thread mills require only eight stock standard tool sizes to produce 100+ commonly produced screw thread designations," said the spokesperson. "They provide easy machining of difficult materials, one tool for through and blind holes and total control over pitch diameter limits. SHUR-THREAD GFI-IKZ thread mills with internal coolant offer a balance of performance and price with specially engineered multiple-spiral flutes to eliminate chatter, a large cutter diameter with high profile correction to ensure true-to-gauge threads and an extended milling portion which allows for 2xD length of cut.

"For optimal results, Emuge recommends that tools from the Titanium Program run on a CNC machine with a synchronous spindle utilizing a tap holder with minimal compensation, such as Emuge Softsynchro, which features patented construction separation of the transmission of torque and axial force for the best tool life and thread surface quality."
