EC-550 HMC

The EC-550 horizontal machining center features a 30" x 34" x 32" work envelope, 50-taper geared-head spindle, dual pallet changer with 550mm pallets, 50-pocket side-mount tool changer, and a built-in 1° pallet indexer. EC-550's standard geared head couples the motor directly to the spindle through a Haas-built, high-precision gearbox. The two-speed gearbox provides 450ft/lb of torque for heavy material removal, and speeds to 6,000rpm for finish cuts. For high-speed work, an optional 10,000rpm inline directdrive spindle is available. Driven by a 45hp vector dual-drive system, the spindle yields 170ft/lb of torque at 1,400rpm and has a peak power rating of 60hp at 7,000rpm.

Each of the EC-550's pallets handles a 2,205 lb load, and the servo-driven palletchanger 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.

For long-cycle production with minimal downtime, the EC-550 is equipped with a large-volume coolant tank and a high-capacity belt conveyor for efficient chip removal.

Also on display will be the EC-630PP HMC Pallet Pool; the Mini Mill 2; and ST-30 Turning Center.
