Overview
The Haas EC-400 is a 40-taper horizontal machining center built around two 15.75 in (400 mm) pallets, with 22 × 25 × 22 in (559 × 635 × 559 mm) of travel and a full B axis that positions in 0.001° steps. It sits below the EC-500, which has 19.69 in (500 mm) pallets and 32 in (813 mm) of X travel.
The inline direct-drive spindle is rated 30 hp (22.4 kW) and 8,100 rpm, with 90 ft-lbf (122 N·m) at 2,000 rpm, in CT40, BT40 or HSK-A63. Rapids are 1,400 ipm (35.6 m/min) and the cutting feedrate reaches 833 ipm (21.2 m/min). The side-mount changer holds 30+1 tools and swaps them in 2.8 s tool-to-tool, 3.6 s chip-to-chip. Haas also offers a 100-pocket tool changer for high-volume production.
Each pallet takes 880 lb (400 kg), and a pallet change takes 15 s. That load includes the tombstone or fixture, so it is the figure to check first for steel or cast iron parts on a four-sided fixture. With a pallet pool the table gives a lower limit of 500 lb (227 kg) per pallet. The B axis turns at 150°/sec, makes a quarter turn in 3 s, and is listed at ± 15 arc-sec indexing accuracy and 10 arc-sec repeatability, with a 2,500 ft-lbf (3,390 N·m) brake. Haas's feature list names a cycloidal rotary drive and hydraulic pallet clamping.
Y travel, at 25 in (635 mm), is longer than X or Z. That favours tall tombstones on a small pallet. Thrust is 3,380 lbf (15,035 N) on X and Z and 2,810 lbf (12,500 N) on Y. Other listed features are a stepped base and column, a coolant ring, rear chip discharge, a pallet schedule table and an automatic probe riser.
The machine uses 9 scfm of air at 100 psi (255 L/min at 6.9 bar), and 100 psi is also the minimum supply pressure, so a compressor that sags below that will not do. Electrical supply is 220 VAC at 70 A or 440 VAC at 35 A, three-phase. Shipping weight is 17,520 lb (7,947 kg). Haas lists a starting price of US$244,995.

Strengths & Limitations
Strengths
- Two 15.75 in (400 mm) pallets with a 15 s pallet change keep the spindle cutting while the other pallet is loaded
- 1,400 ipm (35.6 m/min) rapids with 2.8 s tool-to-tool and 3.6 s chip-to-chip tool changes
- Full B axis with 0.001° resolution, ± 15 arc-sec indexing accuracy and a 2,500 ft-lbf (3,390 N·m) brake
- 25 in (635 mm) of Y travel over a 400 mm pallet, the same Y as the larger EC-500
- Spindle taper is a choice of CT40, BT40 or HSK-A63
- A 100-pocket tool changer is available for jobs that outgrow 30+1 tools
Limitations
- Pallet load is 880 lb (400 kg) including the fixture, and the table gives 500 lb (227 kg) with a pallet pool

Frequently Asked Questions
01
880 lb (400 kg) per pallet, which is also the maximum weight on the B-axis platter. Fixture and tombstone count toward it. The table gives a separate figure of 500 lb (227 kg) maximum pallet load with a pallet pool, so check that limit if the machine is being configured for pooled pallets.
02
Pallet size and travel. The EC-400 has 15.75 in (400 mm) pallets and 22 × 25 × 22 in (559 × 635 × 559 mm) of travel. The EC-500 has 19.69 in (500 mm) pallets and 32 × 25 × 28 in (813 × 635 × 711 mm). Spindle, rapids, tool capacity and the 880 lb (400 kg) pallet load are the same in the figures for both, and the EC-500 weighs 20,120 lb (9,126 kg) against 17,520 lb (7,947 kg).
03
Minimum resolution is 0.001°, indexing accuracy is ± 15 arc-sec, repeatability is 10 arc-sec and backlash is 30 arc-sec. The axis rapids at 150°/sec and a quarter-turn index takes 3 s. Rotational torque is 424 ft-lbf (575 N·m) through a 106:1 gear ratio, and the brake holds 2,500 ft-lbf (3,390 N·m).
04
The side-mount changer holds 30+1 tools. With every pocket full a tool can be 2.5 in (64 mm) in diameter; with the adjacent pockets empty the limit is 5 in (127 mm). Maximum length is 12 in (305 mm) and maximum weight 12 lb (5.4 kg). Changes take 2.8 s tool-to-tool and 3.6 s chip-to-chip. A 100-pocket changer is available.
05
Air consumption is 9 scfm at 100 psi (255 L/min at 6.9 bar), with a minimum supply pressure of 100 psi (6.9 bar) through a 1/2 in hose and coupler. Electrical supply is 220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A. The coolant tank holds 95 gal (360 L).
06
Haas's feature list for the EC-400 names a cycloidal rotary drive, a hydraulic pallet-clamping system, a stepped base and column, a coolant ring, chip management with rear chip discharge, a pallet schedule table and an automatic probe riser. It also cites an available 100-pocket tool changer. The list does not say which items are standard, so confirm that on a quotation.
