Overview

The Haas CM-1 is a compact, high-speed machining center built for small precision parts. With a 30,000 RPM spindle on an ISO 20 taper and a 305 x 254 x 356 mm (12 x 10 x 14 in) work envelope, it targets a completely different market than the rest of the Haas vertical mill lineup. This is a machine for medical devices, electronics, watchmaking, small aerospace components, and precision instrument parts.

The spindle runs at 30,000 RPM with 3.7 kW (5 hp) and 10.8 Nm (8 ft-lbf) of torque at 3,000 RPM through a belt-drive system with air/oil injection bearing lubrication. The ISO 20 taper keeps tooling small and light, with a max tool weight of 2.3 kg (5 lb). That's by design: at 30K RPM, you need low-mass tooling to maintain balance and minimize runout.

The table measures 572 x 254 mm (22.5 x 10 in) with three T-slots on 86 mm centers and a 68 kg (150 lb) load capacity. The 20-pocket carousel tool changer posts a 3.2-second tool-to-tool average. Rapid traverse is 19.2 m/min (757 ipm) on all axes.

The CM-1 is compact enough to fit in tight spaces, weighing just 998 kg (2,200 lb). It runs on single-phase 220 VAC at 16 amps or 3-phase at 12 amps, making it accessible to small shops and labs. Coolant capacity is 49 L (13 gal).

At a base price around $78K, the CM-1 competes with benchtop and compact machining centers from Datron, Kern, and Hermle's compact line. It won't match the accuracy of a Swiss-made Kern, but it brings 30K RPM capability at a fraction of the cost with full Haas support behind it. Specs sourced from Haas Automation published data.

Strengths & Limitations

Strengths

30,000 RPM spindle speed is the highest in the Haas lineup and handles micro-milling and fine finishing work
Runs on single-phase 220 VAC at just 16 amps, making it accessible to any shop or lab
998 kg (2,200 lb) is light enough for upper floors and labs without special floor preparation
20-pocket tool changer with 3.2-second tool-to-tool is fast for a compact machine
ISO 20 taper keeps tooling costs low for small-diameter cutters
Full NGC control with the same programming interface as production Haas machines
Minimal air requirements at just 1 scfm versus 4 scfm for larger Haas mills

Limitations

5 hp spindle and ISO 20 taper limit material removal to small cuts in soft materials
305 x 254 mm X/Y travel restricts workpiece size to parts under roughly 10 inches
68 kg (150 lb) table load is very low and limits fixture weight
ISO 20 tooling is less common and has limited options compared to CT/BT 40
Low axis thrust forces (5,111 N) limit cutting forces in harder materials
No high-voltage 440 VAC option listed

Best For

Medical device manufacturers machining small implants, instruments, and components Electronics and connector manufacturers running small precision parts Watchmaking and precision instrument shops needing 30K RPM finishing Small aerospace components in aluminum, titanium, and engineering plastics Engraving and micro-milling applications requiring high spindle speed R&D labs and universities that need a compact, low-power CNC mill

Frequently Asked Questions

01 What does a Haas CM-1 cost?

Base price is approximately $78,000. With probing and common options, expect $85,000-$95,000. The CM-1 is competitively priced against other compact high-speed machines, though premium brands like Kern and Datron offer higher accuracy at 2-3x the price.

02 What is ISO 20 taper?

ISO 20 is a small spindle taper used on compact and high-speed machines. Tools are smaller and lighter than CT/BT 40, which allows higher RPMs with less vibration. The trade-off is lower tool rigidity and limited availability of larger tooling. Most ISO 20 tools max out around 12mm shank diameter.

03 Can the CM-1 cut steel?

It can cut mild steel and stainless with small tools and light cuts. The 5 hp spindle and ISO 20 taper aren't designed for aggressive steel work. The CM-1 excels in aluminum, brass, plastics, and other soft materials where 30K RPM and fine detail matter.

04 How does the CM-1 compare to a Datron?

Datron machines are purpose-built for high-speed aluminum and non-ferrous work with higher accuracy and better surface finish. The CM-1 offers a full enclosure, more robust construction, and the familiar Haas control at a lower price. For pure precision in soft materials, Datron wins. For versatility and value, the CM-1 is competitive.

05 Does the CM-1 need special power?

No. It runs on standard 220 VAC single-phase at just 16 amps or 220 VAC 3-phase at 12 amps. That's less power draw than most household electric dryers, making installation straightforward in any facility.
