Introducing the powerful 40" x 20" x 20" Acra Vertical Machining Center with Mitsubishi CNC Controller - a premium Taiwanese-made VMC designed for high-precision machining across a wide range of applications. This robust machine combines outstanding rigidity, stability, and performance to deliver exceptional results on every job.

The 40" x 20" x 20" Acra VMC features a rugged box-way design with major cast components for maximum rigidity and vibration dampening. The precision-ground boxways and meticulous way lube system ensure smooth, accurate motion. The thermally-optimized head counterbalance minimizes vibration for superior finish quality. Powered by robust servo motors and a 20HP high-torque spindle that reaches 8,000RPM, this VMC tackles heavy cuts with ease. The rigid tapping, chip auger, and full enclosure contribute to high productivity.
