The A72 model features 28" × 18" × 28" travel, the A85 features 33" × 23" × 22" travel, and the A110 features 43" × 23" × 22" travel. Z-axis acceleration of 0.75G minimizes tool-change time. A direct-coupling 12,000-rpm spindle is available optional speeds of 15,000, 18,000 or 20,000 rpm. The machine also features a Fanuc Oi-MD (10.4" LCD display) with AICC-2 (200 blocks look ahead) or 21i-MB control.
The VMCs have high-damping, rigid guideways. Ballscrew holders are directly casted to increase rigidity and strength, ensuring constant support for the ballscrews over the machine’s life. Large-diameter ballscrews measuring 1.77" as well as 1.77"-wide linear guides ensure stiffness during machining. Direct-coupling servo motors eliminate motor backlash and noise caused by misalignment.
Directly coupled spindles with two types of high-torque spindle motors can mill steel and aluminum. The machines use oil-air lubrication with a filtration system for spindle bearings, and an air dryer further ensures air quality and service life, the company says.
