Verdict
These machines serve different jobs. The Haas CM-1 is for small medical, electronics and watch parts, engraving and micro-milling, where a 30,000 rpm spindle and small footprint fit the work. The Haas VS-3 is for large weldments, mold bases, fixture plates and energy-sector parts up to 150 in long and 10,000 lb, where 50-taper torque and the large table are the point.
