Fanuc Robodrill α-D21MiB5 vs Haas CM-1
Fanuc vs Haas Automation · Vertical Machining Centers
Summary
The Fanuc Robodrill α-D21MiB5 and the Haas CM-1 are both compact vertical machining centers, but they sit in different size classes and serve different jobs. The Robodrill is a 30-taper production machine with 400 mm (15.7 in) of Y travel, a 750 x 400 mm (29.5 x 15.7 in) table and a 300 kg (661 lb) load limit. The CM-1 is a small ISO 20 mill with 10 in (254 mm) of Y travel and a 150 lb (68 kg) limit.
The Robodrill has the stronger spindle, 11 kW (15 hp) against 5 hp (3.7 kW), a 0.7 sec tool change against 3.2 s, and 54 m/min (2,126 ipm) rapids against 757 ipm. The CM-1 spins to 30,000 rpm against 10,000 RPM standard, has 14 in (356 mm) of Z travel against 330 mm, and weighs 2,200 lb (998 kg) against ~3,900 kg.

Verdict
These machines serve different jobs. The Fanuc Robodrill α-D21MiB5 is for high-volume production cells drilling, tapping and milling aluminum and light-alloy parts, where 0.7 sec tool changes, 54 m/min rapids and a 300 kg table keep cycle times short. The Haas CM-1 is for small medical, watch and electronics parts, engraving and lab work, where a 30,000 rpm spindle on a compact machine matters more than speed between cuts.
