Largest Haas accommodates parts up 1,000 mm height/diameter

The EC-630 is the largest-capacity, high-production machine Haas has yet produced. It features a 1,015 by 840 by 890 mm work envelope, 50-taper geared-head spindle, dual pallet changer with 630 mm pallets, 50-pocket side-mount tool changer and a built-in 1-degree pallet indexer (a full 4th axis is available). The machine’s enclosure accommodates parts up to 1,000 mm in both diameter and height. The EC-630’s geared head couples the motor directly to the spindle through a Haas-built, high precision gearbox. The two-speed gearbox provides 610 Nm of torque for heavy material removal, and speeds to 6,000 rpm for finish cuts. Each of the machine’s 630 mm pallets handles a 1,200 kg load, and the servo-driven pallet-changer swaps pallets quickly. A separate, protected load station allows the operator to safely load and unload parts or change fixtures on one pallet, while parts are being machined on the other – keeping spindle run-time at a maximum.
