The Haas EC-400 is a 40-taper, twin-pallet horizontal machining center with a reputation for dependable, high-volume production and easy unattended running. This 2012 machine pairs two 400 mm (15.75 inch) pallets on an automatic pallet changer with a rotary B-axis, X, Y, and Z travels of 20 x 20 x 20 inch, and a 12,000 RPM, 30 HP CT40 inline spindle running 1,000 ipm rapids. It is equipped with through-spindle coolant, spindle and tool-setting probing, a 40-pocket side-mount tool changer, and a chip conveyor, and carries up to 660 lb on each pallet. The horizontal layout lets chips fall clear of the cut for cleaner, longer unattended runs.
Compared to the earlier Haas HS-series horizontal machining centers it followed, the EC-400 packs true twin-pallet, 400 mm production into a far more compact, shop-friendly footprint. Where the larger HS machines demanded significant floor space, the EC-400 brings an integrated automatic pallet changer, a rotary B-axis pallet, and a modern Haas control into a cell-ready package, so smaller shops get genuine horizontal, pallet-changing throughput. For a buyer who wants the chip-clearing and unattended advantages of an HMC without an oversized machine, this EC-400 delivers proven Haas horizontal performance in a right-sized platform.
