Multiple technologies on the a51nx reduce non-cut time, providing benefits in automotive and high volume part production.  An Inertia Active Control system monitors motor load and estimates total fixture weight.  With this information IAC optimizes the motion acceleration and deceleration of the heavily utilized B and Z-axis.  The spindle takes full advantage of the duty rated torque to optimize start / stop responsiveness, leading to 20% reduction in tapping time compared to the previous model. 

A standard Vision type Broken Tool Sensor resides in the ATC magazine where it automatically confirms the condition of drills, taps and other single point tools.  Unique single piece way-cover design, dual-supported tool-change arm and Makino spindle technology provide the foundation for industry-leading reliability.
