Haas EC-400 HMC

The high-productivity features on the new Haas EC-400 HMC include 20" x 20" x 20" work cube, dual 400 mm pallets, 1-degree indexing, an 80-gallon coolant system and triple-auger chip removal. The standard 8,000-rpm, 40-taper spindle is powered by the Haas 20-hp vector dual drive system; an optional 30-hp, 12K spindle is also available. Both spindles feature an inline, direct-drive system that couples the motor directly to the spindle, for less vibration, less heat and less noise than belt- or gear-driven systems – which means superior surface finishes, excellent thermal stability and quieter operation. A 24+1 side-mount tool changer and 500-ipm cutting feeds are also standard.The Haas control features advanced tool management, single-button features, 15-inch color LCD monitor and a 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. 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
