The 10,000-rpm high-speed, high-power spindle features 37kW of duty rated power and 512 Nm of duty rated torque. The machines stiffness and rigidity supports thorough utilization of the spindle power and torque to tackle a wide variety of ferrous, non-ferrous and hard metal applications. Multiple technologies on the a71nx reduce non-cut time, providing benefits in automotive and high volume part production.
Most notably is the standard direct drive NC rotary table. The responsiveness of this table eliminates non cut time by reducing 90° indexing time to just 1 second. The DD NC rotary table also supports Makino’s innovative Inertia Active Control (IAC) system. IAC monitors B-axis 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.
