The a71 horizontal high-speed milling machine is rapidly becoming one of the most popular platforms for high-volume machining of parts made of cast iron and light alloys. Spindle integration with the drive motor rotor reduces vibration during high-speed milling operations and increases acceleration/deceleration. Rapid spindle acceleration to top speed in just 2.4 seconds helps substantially reduce non-cut time. The center trough quickly removes large chip volumes for enhanced reliability in continuous high-speed milling machining applications.
