Haas Automation vs Haas Automation · Horizontal Machining Centers
Summary
The Haas EC-1600ZT-5AX is the five-axis version of the Haas EC-1600ZT. On the published figures the two share a frame and a spindle: 64 x 50 x 40 in (1,626 x 1,270 x 1,016 mm) of travel, a 10,000 lb (4,536 kg) table load, a 7,500 rpm 50-taper spindle with 30 hp (22.4 kW) and 340 ft-lbf @ 700 rpm, 50+1 tools and an 8 s tool change.
The differences are the table and the list price. The Haas EC-1600ZT has a 64 × 36 in (1,626 × 914 mm) table; the Haas EC-1600ZT-5AX has a 64 × 32 in (1,626 × 813 mm) table and adds an A-axis platter for compound-angle work. Haas lists the Haas EC-1600ZT at US$376,995 and the Haas EC-1600ZT-5AX at US$509,995.

Advantages
Haas EC-1600ZT
- Lower published list price, US$376,995 against US$509,995
- Wider table, 64 × 36 in (1,626 × 914 mm) against 64 × 32 in (1,626 × 813 mm)
- Same travels, 30 hp (22.4 kW) spindle and 50+1 tools for work that needs no tilting axis
Haas EC-1600ZT-5AX
- Adds an A-axis platter for compound-angle and five-axis machining
- Keeps the 64 in (1,626 mm) X travel, 10,000 lb (4,536 kg) table load and 340 ft-lbf spindle of the base machine
Verdict
Buy the Haas EC-1600ZT-5AX only if the parts need compound angles or five-axis roughing in one setup; that capability is what the higher list price of US$509,995 pays for. For deep housings, frames and heavy rotary-indexed parts machined on their faces, the Haas EC-1600ZT does the same work with the same travels, 30 hp (22.4 kW) spindle and 50+1 tools at US$376,995, and with a wider 64 × 36 in table.
