At IMTS 2016, Mazak demonstrated its full fi ve-
axis Variaxis i-800T Multi-Tasking Machine that can be equipped with a cryogenic through-tool cooling system from 5ME, which delivers super-cold liquid nitrogen to the cutting edge. The system ensures that nitrogen does not become a gas before having the opportunity to cool the tool. “This keeps the cutting edges at a consistent temper- ature so they last longer and you can push the tool harder,” said Kerscher. Finally, greater adoption of available technology can make a major impact. “I still see many shops using 15-year-old methods to machine Ti,” said Terryberry. “They’re stepping down with a small tool, taking an 1/8th of an inch, which is very hard on the tool. The same 3 or 4 mm of the tool gets worn away quickly. Contrast that with shops using the full length of the end mill with adaptive toolpaths. They are step- ping over radially instead of axially and taking the entire DOC in one shot, so they are taking many fewer passes. They’re making the part in six hours instead of 16.”
The Emuge titanium tap Rekord 2D-Ti has an optimized fl ute angle and profi le for tough, long chips that evacuate on one direction , making it appropriate for diffi cult-to-machine titanium grades.
“As titanium alloys become more commonplace, and even though we look at it as the ‘aluminum’ of the 21st Century, the ability to master this amazing material remains elusive,” he said. “With the introduction of beta phase titanium, tech- nologies such as additive, ultrasonic machining and cryogen- ics are poised to make the next major breakthroughs.”
