Process: Turning


The QUICK TURN NEXUS (QTN) 500 turning center with a large spindle bore packs the speed, power and precision that’s required for the heavy-duty machining of long, large workpieces, especially those produced for the energy and heavy equipment industries.

As a two-axis configuration in the QUICK TURN NEXUS Series, the machine provides efficient part processing and features a gear-driven spindle headstock, a massive turning turret and CNC programmable tailstock. And Mazak’s MX Hybrid Roller Guide System ensures optimum vibration dampening, extended tool life and the shortest possible cycle times through fast acceleration/deceleration speeds.

Additionally, the QTN 500 pairs with an optional, highly unique tailstock design that combines a standard tailstock with a long boring bar (LBB) to achieve deep-hole boring depths of 46".


  • Advanced gear-driven spindle headstock offers maximum power for heavy metal cutting
  • Spindle through-bore diameter size of 7.2"
  • Massive 15-position drum turret (10 O.D., 5 I.D.) offers heavy cutting capability
  • Available rear-mounted chucks add stability for machining long bars and pipes
  • CNC programmable tailstock for precise support
  • MX Hybrid Roller Guide System delivers durability and reliability for long-term accuracy
  • Optional automatic tool eye system detects tool wear and damage
  • Advanced CNC technology offers easy programming and fast job setup
  • Optional LBB/tailstock combination offers deep-hole boring/milling capability
  • Pairs with a variety of chip conveyor system configurations for effective chip management
