Original Press Release:
Haas Expands Horizontal Line
Haas Automation's new generation of horizontal machining centers - the EC Series - is designed to meet the needs of today's customers right out of the box - without requiring them to invest in a lot of expensive options. The performance is built into the machine.
The latest addition to the Haas EC Series is the EC-500. It features a 32" x 20" x 28" work cube, a dual pallet changer with 500 mm pallets and a built-in pallet indexer. The machine comes standard with an 8,000-rpm, 40-taper spindle powered by a 20-hp vector dual drive system. Also standard are a side-mount tool changer (24+1 tools), 1000-ipm rapids and a high-volume coolant system. To eliminate downtime associated with manual chip removal, the EC-500 is equipped with a triple-auger chip conveyor system that removes chips from the enclosure quickly and efficiently. A belt-style chip conveyor is also available.
For added performance, a 12,000-rpm spindle powered by a 30-hp vector dual drive system is available as an option. This spindle provides additional horsepower for heavy cuts, as well as 50% more speed for high-speed machining operations. Both spindles feature a unique inline, direct-drive system that couples the motor directly to the spindle rather than using belts. This results in better surface finishes, extreme thermal stability and quiet operation. On-the-fly wye-delta switching provides plenty of low-end torque and a wide constant-horsepower band, without having to stop the spindle to change windings.
The EC-500 comes standard with a pallet indexer that provides 45-degree incremental indexing for multi-sided tombstones. The machine's generous enclosure allows a maximum part swing of 29.5" on the indexer, with a maximum swing of 71" for the pallet changer. For extremely accurate positioning and extra rigidity for heavy off-center milling, a high-precision face-gear indexer (1-degree indexing) is available as an option. A full 4th-axis is also available.
The servo-driven pallet changer on the EC-500 swaps pallets in just 9 seconds, and each 500 mm pallet has a load capacity of 1,000 lb (660 lb with full 4th axis). 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.
The standard side-mount tool changer on the EC-500 holds 24+1 tools, and features a quick-change double-arm gripper that swaps tools in just 2.8 seconds. To reduce cycle times further and increase tool capacity, either a 40- or 60-pocket servo-driven SMTC is available. Both optional tool changers reduce tool-to-tool times to 1.6 seconds.
