Haas Automation publishes a list price of US$244,995 for the Haas EC-400 (verified 2026-10-02). Options, tooling, freight and installation are extra, so a dealer quote will differ. A specific price can be requested at https://machinetoolindex.com/machines/haas-ec-400#price; the request is passed to Haas Automation or an authorised dealer.
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.
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).
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).
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.
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).
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.
