MAG highlighted cryogenic machining at EMO last week! The revolutionary cryogenic, through-the-tool machining system was actually presented on four high performance machine tools and a robotic system using the new, eco-friendly liquid nitrogen coolant.
MAG’s newly developed liquid nitrogen cooling system was introduced to the public last fall, finally succeeding in implementing this radically new way to work. Within a short time span, the MAG experts were able to develop a practical, through-the-tool system effectively, applying it to different materials and machining technologies.
Wide spectrum of application Four cryo equipped machines were displayed at EMO, demonstrating breakthrough applications in difficult to machine materials:
- an aerospace titanium blisk on a vertical machining center NBV 700 5X
- an Inconel part on a vertical turning center VDM 1000
- a hardened shaft on a turn/mill center VDF 450 TM
- a CGI crankcase on the hydraulic-free SPECHT 600 E Also, a robotic root end drilling system equipped with cryogenic technology was able to demonstrate how easy composites material machining can be, if it’s done at the right temperature. Wind turbine manufacturers will benefit greatly from this new development.
Main benefits of cryogenic machining According to MAG’s numerous tests, the following results can be highlighted (compared to classical machining): Aerospace titanium bliskfor aircraft turbine
- Increase tool contact angle during trochoid five axis milling (Up to 30% higher feed rate)
- Tool life doubled Inconel ring
- Tool life doubled for ceramic rough and carbide finish turning
- 30% productivity gains Drive shaft (see picture)
- Up to double tool life
- Up to 50 % increased cutting speed GCF root end of wind Turbine blade
- 30% higher cutting rate
- Significantly higher productivity, machine 150 more blades per year capital investment GCI Cylinder block
- Approximately 25 % higher output reduces capital investment (4 instead of 5 machines)
These results are quite impressive and this also stunned the jury of the EMO innovation award as MAG won this trophy for its cryogenics technology.
"This is one of the greatest breakthroughs in the history of metalworking and it promises to rewrite the book on machining speeds and costs for difficult to machine materials, which are critical in aerospace, and coming into common use in automotive and general industry applications as well," said Michael Judge, Vice President of Cryogenic Business Development.
