The high-productivity features on the Haas EC-400 horizontal machining center include 20″ x 20″ x 20″ (508 x 508 x 508 mm) work cube, dual 400 mm pallets, 1-degree indexing, a 95-gallon (360 liter) coolant system and triple-auger chip removal. The standard 8000-rpm, 40-taper spindle is powered by the Haas 20 hp (14.9 kW) vector drive system; an optional 30-hp (22.4 kW) , 12 K spindle is also available.
Both spindles feature an inline, direct-drive system that couples the motor directly to the spindle, for less vibration, heat and noise – which means superior surface finishes, excellent thermal stability and quieter operation. A 24+1 side-mount tool changer and 500 ipm (12.7 m/min) cutting feeds are also standard.
The Haas control features advanced tool management, single-button features, 15″ color LCD monitor and USB port.
The servo-driven pallet changer on the EC-400 swaps pallets in just 8 seconds, and each 400 mm pallet has a load capacity of 1000 lb (454 kg). A separate load station allows the operator to safely load/unload parts or change fixtures on one pallet while parts are being machined on the other, keeping spindle run time at a maximum.
For extremely accurate positioning of multi-faceted parts, a high-precision face-gear indexer — providing 1-degree indexing — is standard. A full 4th-axis rotary table is also available for shops requiring simultaneous 4-axis motion, and a 5th axis can be added for complex work.
