a81 SPECIFICATIONS

a81 Horizontal Machining Center

Like the a71, the a81 is rapidly becoming one of the most popular platforms for high-volume machining of parts made of cast iron and light alloys. Makino's spindle integration with the drive motor's rotor reduces vibration during high-speed operation and increases acceleration/deceleration. Rapid spindle acceleration to top speed in just 2.4 seconds helps reduce non-cut time substantially. Center trough quickly removes large chip volumes for enhanced reliability in continuous machining.
