Machine Comparison
Haas CM-1 vs Haas DC-1
Haas Automation vs Haas Automation · Vertical Machining Centers
Summary
The Haas CM-1 and the Haas DC-1 are both small Haas vertical machines, but they do different jobs. The Haas CM-1 is a compact mill for micro-milling and engraving, with a 30,000 rpm ISO 20 spindle and 12 in (305 mm) of X travel. The Haas DC-1 is a drill and tap machine with a 10,000 rpm BT30 spindle and 23.6 in (600 mm) of X travel.
The Haas DC-1 is stronger on almost everything except spindle speed: 15 hp (11.2 kW) against 5 hp (3.7 kW), a 550 lb (250 kg) table load against 150 lb (68 kg), and 1.5 s tool changes against 3.2 s. The Haas CM-1 has three times the spindle speed and slightly more Z travel, 14 in (356 mm) against 13 in (330 mm). Haas lists the Haas CM-1 at US$77,995 and the Haas DC-1 at US$69,995.

Verdict
Choose by the work. The Haas CM-1 is for micro-milling, engraving and fine-detail finishing with small cutters, where 30,000 rpm matters more than torque and parts stay under 150 lb (68 kg). The Haas DC-1 is for drilling, tapping and light milling of larger parts in volume: it has 15 hp (11.2 kW), a 1.5 s tool change and 23.6 in (600 mm) of X travel, and it lists lower at US$69,995.
