Multi-Function Machine Features Cryogenic Cooling

Mazak’s Variaxis i-800T is a multi-function machine that features full five-axis milling and turning capabilities along with integrated liquid nitrogen cryogenics technology. The cryogenic system freezes cutting tools from the inside out, and keep the cutting tips/edges in a frozen state while workpiece materials remain in an ambient state. According to the company, this prevents heat or thermal effects from transferring into workpieces so that base material integrity is maintained. The system is said to facilitate faster machining speeds and feeds, extend tool life, help prevent burrs, and contribute to the reduction of overall cost per part because of its ability to remove white layers when machining complex aerospace parts from materials such as titanium, nickel, Invar and other exotics.

Mazak will demonstrate the Variaxis i-800T cutting an aerospace jet-engine blisk. The machine will feature an 80-position ATC magazine for increased productivity and a 10,000-rpm, CAT-50 spindle. The machine’s trunnion-style tilting table and multi-tasking capability enable users to reduce the inaccuracies that occur when moving parts across multiple workstations, the company says as well as reduce work-in-process inventory and increase overall throughput.
