The a81nx expands part size capacities through enhanced table and column castings that coupled with an additional 100mm of Y-axis stroke produce 12.5% more work envelope.  Robust 3-roller style B-axis table bearings ensure stable cutting throughout this new found work zone.  Large parts frequently mean large features too.  Tool length, diameter and weight capacities of the a81nx have all increased to support large face mills, boring bars and line bar applications.

Two new spindle designs provide productivity improvements in cutting and non-cutting performance.  The optional 8,000 RPM high torque spindle boosts continuous power levels by 19% over the previous model.  With 50 HP of continuous power, this high torque spindle is ideally suited for heavy roughing of iron castings and hard metal aerospace applications.  Both the 8,000 RPM and standard 10,000 RPM spindles feature significant improvements in acceleration and deceleration that reduce rigid tapping times by up to 30%.

Reliability and ergonomics are clear a81nx design objectives.  Proven technologies like single piece X & Z axis way covers and servo driven ATC shutters, ensure that the a81nx continues the Makino tradition of producing HMC’s with the highest levels of reliability.  The ergonomic focus is easily understood simply by looking at the ATC magazine.  All a81nx ATC magazines include a tool loading station (TLS).  This cam actuation device ejects the tool from the pot into a rail guided tool drawer.  Even maximum weight / diameter tools can be safely and quickly exchanged.
