Haas EC-300 Horizontal Machining Centre
The Haas EC-300 HMC is a compact horizontal machining centre with a generous 381 x 381 x 254 mm (xyz) work envelope, a twin pallet changer and built-in tombstone indexing capabilities. The machine is equipped with an 8,000-rpm, 40-taper spindle that features a unique inline, direct-drive system that couples the motor directly to the spindle rather than using belts or gears. This results in less vibration, less heat and less noise than other drive systems, providing better surface finishes, extreme thermal stability and very quiet operation. Powered by a 20-hp vector dual drive system with on-the-fly wye-delta switching, the spindle yields plenty of low-end torque and a wide constant-horsepower band.
To boost production, the EC-300 features a built-in twin pallet changer (300 mm pallets) that allows the operator to load and unload parts on one pallet while the machine mills parts on the other. Once machining is complete, a servo-driven changer swaps pallets in approximately 2 seconds to maintain nearly constant spindle time. A full fourth axis rotary table is standard.
High-lead ballscrews and high-torque servo motors on all axes provide rapids up to 30 m/min and high accelerations to reduce cycle times, and a 24+1 side-mount tool changer swaps tools in just 2.8 seconds to keep non-machining time to a minimum.
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 more horsepower than the standard spindle, as well as additional speed for high-speed machining operations. To further reduce cycle times, a high-speed, servo-driven tool changer (1.6 seconds tool to tool) is also available.
