Haas Automation vs Haas Automation · Horizontal Machining Centers
Summary
The Haas EC-1600ZT-5AX and Haas EC-400 serve different jobs. The EC-1600ZT-5AX is a large 50-taper horizontal with 5-axis capability and 64 in (1,626 mm) of X, 50 in (1,270 mm) of Y and 40 in (1,016 mm) of Z travel. The EC-400 is a compact 40-taper pallet HMC with 22 in (559 mm), 25 in (635 mm) and 22 in (559 mm).
Both spindles are rated 30 hp (22.4 kW). The EC-1600ZT-5AX delivers 340 ft-lbf @ 700 rpm against 90 ft-lbf @ 2,000 rpm and carries 50+1 tools against 30+1. The EC-400 is faster between cuts, with 2.8 s tool changes against 8 s and 3.6 s chip-to-chip against 12.6 s, and spins to 8,100 rpm against 7,500 rpm. Haas lists the EC-1600ZT-5AX at US$509,995 and the EC-400 at US$244,995.

Advantages
Haas EC-1600ZT-5AX
- 64 in (1,626 mm) of X travel against 22 in (559 mm)
- 340 ft-lbf (460 N·m) of torque against 90 ft-lbf (122 N·m)
- 50+1 tools against 30+1
- Fifth-axis capability for compound angles on large parts
Haas EC-400
- 2.8 s tool-to-tool against 8 s
- 3.6 s chip-to-chip against 12.6 s
- 8,100 rpm spindle against 7,500 rpm
- Lower published list price, US$244,995 against US$509,995
Verdict
Pick by part size. The EC-1600ZT-5AX is for aerospace, energy and heavy equipment shops that machine large components with angled features, where 64 in (1,626 mm) of X travel, 340 ft-lbf of torque and 5-axis positioning save refixturing. The EC-400 is for mid-volume production of smaller aluminum and steel parts on pallets, where 3.6 s chip-to-chip time and a US$244,995 list price make more sense than a large 5-axis machine.
