Overview

The Haas CM-1 is a compact vertical mill built around one number: a 30,000 rpm spindle. Travels are 12 × 10 × 14 in (305 × 254 × 356 mm), the spindle is an ISO 20 taper rated 5 hp (3.7 kW), and the whole machine ships at 2,200 lb (998 kg). It is a machine for very small tools and very small parts, and the rest of the table follows from that.

Spindle torque is 8 ft-lbf (10.8 N·m) at 3,000 rpm. That is enough for small cutters in aluminium, brass, plastics and graphite and for light finishing in steel, but it is not a spindle for face mills or large drills. The Mini Mill makes the contrast clear, with 45 ft-lbf (61 N·m) at 500 rpm from a 40-taper spindle that stops at 8,000 rpm. Bearings are lubricated by air/oil injection and the spindle is air cooled.

Workholding space is tight. The table measures 22.5 × 10 in (572 × 254 mm) with three T-slots on 3.38 in (86 mm) centres, and it carries 150 lb (68 kg). X travel covers 12 in (305 mm) of that table length, so a part has to sit inside the travel window, not merely on the table. Clearance between spindle nose and table runs from 2.6 in (66 mm) to 16.6 in (422 mm).

The 20-tool carousel changes tool-to-tool in 3.2 s and accepts tools up to 2.3 in (58 mm) in diameter and 5 lb (2.3 kg). Rapids are 757 ipm (19.2 m/min), cutting feed reaches 500 ipm (12.7 m/min), and each axis has 1,149 lbf (5,111 N) of thrust. Installation is light: 16 A of 220 VAC single-phase or 12 A three-phase, and 1 scfm of air at 100 psi. Haas lists a starting price of US$77,995.

Strengths & Limitations

Strengths

30,000 rpm ISO 20 spindle for very small tools, with air/oil injection bearing lubrication
Runs on 220 VAC single-phase at 16 A, or three-phase at 12 A, and uses only 1 scfm of air at 100 psi
Ships at 2,200 lb (998 kg), less than half the 4,450 lb (2,018.5 kg) of the Mini Mill
20-tool carousel, so small parts that need many tools run without manual tool changes
14 in (356 mm) of Z travel, more than its 12 in (305 mm) of X or 10 in (254 mm) of Y, leaves height for vises and fixtures

Limitations

5 hp (3.7 kW) and 8 ft-lbf (10.8 N·m) at 3,000 rpm rule out heavy cuts, large drills and face mills
Travels of 12 × 10 × 14 in (305 × 254 × 356 mm) and a 150 lb (68 kg) table load restrict it to small parts
ISO 20 tools are limited to 2.3 in (58 mm) in diameter and 5 lb (2.3 kg), and holders from a 40-taper machine such as the Mini Mill cannot be used in it
Tool changes take 3.2 s tool-to-tool, which adds up on parts with many short operations
Rapids of 757 ipm (19.2 m/min) are well below the DM-1, which moves at 2,400 ipm (61 m/min)

Best For

Micro-milling and engraving with small cutters at up to 30,000 rpm Small parts that fit within 12 × 10 × 14 in (305 × 254 × 356 mm) Workshops and labs with only 220 VAC single-phase power Fine-detail finishing where tool diameter, not torque, sets the spindle speed Light fixtures and parts under the 150 lb (68 kg) table limit

Frequently Asked Questions

01 What is the CM-1 used for?

Small parts cut with small tools. The spindle runs to 30,000 rpm but is rated 5 hp (3.7 kW) and 8 ft-lbf (10.8 N·m) at 3,000 rpm, so it suits cutters that need speed more than torque. Travels of 12 × 10 × 14 in (305 × 254 × 356 mm) and a 150 lb (68 kg) table load set the upper limit on part size.

02 Can the CM-1 run on single-phase power?

Yes. Haas lists 220 VAC single-phase at 16 A as well as 220 VAC three-phase at 12 A, and the table shows no higher-voltage supply for this model. Air demand is 1 scfm (28 L/min) at 100 psi, with a minimum supply pressure of 80 psi (5.5 bar), through a 3/8 in hose and coupler.

03 How does the CM-1 compare with the Mini Mill?

The CM-1 is smaller, lighter and much faster at the spindle. It has 12 × 10 × 14 in (305 × 254 × 356 mm) travels, a 30,000 rpm ISO 20 spindle with 5 hp (3.7 kW), and a 150 lb (68 kg) table load. The Mini Mill has 16 × 14 × 15 in (406 × 356 × 381 mm) travels, an 8,000 rpm 40-taper spindle with 10 hp (7.5 kW), and a 500 lb (227 kg) table load.

04 What tools does the CM-1 tool changer hold?

A 20-pocket carousel of ISO 20 holders. Each tool can be up to 2.3 in (58 mm) in diameter and 5 lb (2.3 kg), and a tool-to-tool change takes 3.2 s. The table gives no maximum tool length, so check long tools against the 2.6 in (66 mm) minimum and 16.6 in (422 mm) maximum distance from spindle nose to table.

05 How large a workpiece fits on the CM-1 table?

The table is 22.5 × 10 in (572 × 254 mm) with three T-slots, 3.38 in (86 mm) apart, and it is rated for 150 lb (68 kg). Only 12 in (305 mm) of X and 10 in (254 mm) of Y can be reached by the spindle, so features outside that window need a second setup.
