The HAAS EC-1600 Horizontal Machining Center is a robust 50-taper machine designed for large-part precision machining, featuring significant travel distances of 64" in the X-axis, 50" in the Y-axis, and 32" in the Z-axis. Its worktable measures 64" by 36" with 5/8" T-slots spaced 4.92" apart, supporting up to 10,000 lbs of workpiece weight. The spindle is powered by a 30 HP motor with a two-speed geared head delivering up to 6,000 RPM and a maximum torque of 450 ft-lb at 5,000 RPM, optimized for heavy cutting demands. This model integrates a 4th-axis rotary platter of 64" x 32" size with a 30" diameter and supports workpieces up to 10,000 lbs, providing continuous rotational torque of 2,000 ft-lb and a fine backlash precision of 30 arc-seconds, essential for multi-axis milling. The tool changer is a side-mount SMTC type with a 50+1 tool capacity, accommodating tools up to 20" diameter (with a clear adjacent slot) and 30 lbs max tool weight, featuring fast tool-to-tool and chip-to-chip change times of 10.3 and 12.6 seconds respectively. The machine attains rapid feed rates up to 540 in/min on all axes with maximum cutting feedrates of 500 in/min and thrust capacities of 5,600 lbs (X/Y) and 7,500 lbs (Z). Additional features include a 95-gallon coolant capacity, 9 scfm air consumption at 100 psi, and advanced control interfaces with Ethernet, USB, and optional probing systems, aiming to maximize machining efficiency and reduce setup times.
