EC-630 Horizontal Mill for Large Volume Production

Jan. 9, 2009
Designed for high-volume production and unattended operation, Haas' horizontal milling machine has 50-taper power and a large work envelope.

The EC-630 is a large-capacity, high-production horizontal machining center with a 40 x 33 x 35 in. (1016 x 838 x 889 mm) work envelope, 50-taper geared-head spindle, dual pallet changer with 630 pallets, 50-pocket side-mount tool changer, and a built-in 1-deg. pallet indexer (a full 4th axis is available).


The geared head couples the motor directly to the spindle through a Haas-built, high-precision gearbox. The 2-speed gearbox provides 450 ft-lb of torque for heavy material removal and speeds to 6,000 rpm for finish cuts. Each of the machine's 630 mm (25 in.) pallets handles a 2,645 lb. (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. The machine's enclosure accommodates parts up to 39 in. (990 mm) in both diameter and height.


For long-cycle production with minimal downtime, the EC-630 is equipped with a large-volume coolant tank and a high-capacity belt conveyor for efficient chip removal. Also standard are 710 ipm rapids, a 15-in. color LCD monitor with a USB port, 1 MB of program memory, a flood and washdown coolant system, and a programmable coolant nozzle.


To simplify service, the EC-630 spindle, gearbox, and motor are assembled as a single modular unit that is easily removed and installed, if necessary.
