New MTM Offers Full 5-Axis Milling and Turning Along with Cryogenic Technology

At IMTS, Mazak will unveil its new VARIAXIS i-800T Multi-Tasking Machine developed specifically to enhance milling operations and significantly boost productivity -- especially for those manufacturers in the aerospace industry.

With full 5-axis milling and turning capabilities along with integrated liquid nitrogen cryogenics technology, the machine not only delivers high processing efficiency for complex aerospace components, but also prevents the detrimental white layers typically generated when machining those parts from tough materials such as titanium, nickel, Invar and other exotics.

At IMTS, Mazak will demonstrate the VARIAXIS i-800T cutting an aerospace jet-engine blisk. The machine will feature an 80-tool magazine for continuous uninterrupted productivity and a 10,000-rpm, CAT-50 spindle for milling speed and power. The machine's trunnion-style tilting table and multi-tasking capability allows users to reduce the inaccuracies that occur when moving parts across multiple workstations, eliminate work-in-process inventory and increase overall throughput.

With added cryogenics, the VARIAXIS i-800T also significantly increases cutting tool life in addition to eliminating part surface white layers. Mazak's cryogenics freeze cutting tools from the inside out and keeps their cutting tips/edges in a frozen state while workpiece materials remain in an ambient one. In doing so, absolutely zero heat or thermal affects transfer into workpieces so that they maintain their base material integrity. The system also facilitates faster machining speeds and feeds, helps prevent burrs and contributes to the reduction of overall cost per part because processes to remove white layers become unnecessary.

"As with all Mazak technology, we developed the VARIAXIS i-800T with cryogenics to accomplish one key objective -- further improve the performance and productivity of our customer's overall part processing operations," said Dan Janka, executive vice president at Mazak. "And we collaborated with cryogenics pioneer company 5ME to ensure our particular system would truly enhance machining operations and benefit our customers. And we've succeeded."

Janka added that aerospace manufacturers stand to save millions of dollars with the elimination of the processes, intense labor and capital equipment currently involved with the removal of white layers from parts after they have been machined.
