Haas EC-1600 vs Haas EC-1600ZT
Haas Automation vs Haas Automation · Horizontal Machining Centers
Summary
The Haas EC-1600ZT is the EC-1600 large-format horizontal with a longer Z axis. Both share 64 in (1,626 mm) of X and 50 in (1,270 mm) of Y travel, a 64 × 36 in (1,626 × 914 mm) table rated for 10,000 lb (4,536 kg), and the same 7,500 rpm, 30 hp (22.4 kW) 50-taper spindle with 340 ft-lbf @ 700 rpm.
The difference is Z travel: 40 in (1,016 mm) on the EC-1600ZT against 32 in (813 mm) on the EC-1600. Tool capacity (50+1), tool change (8 s), chip-to-chip (12.6 s) and rapids (600 ipm (15.2 m/min)) are identical. Weights are 30,000 lb (13,608 kg) and 29,700 lb (13,472 kg). Haas lists the EC-1600 at US$322,995 and the EC-1600ZT at US$376,995.

Advantages
Haas EC-1600
- Lower published list price, US$322,995 against US$376,995
- Same 10,000 lb (4,536 kg) table rating and 30 hp (22.4 kW) spindle as the ZT
Haas EC-1600ZT
- 40 in (1,016 mm) of Z travel against 32 in (813 mm)
- Reaches deeper into tall parts and long tooling setups on the same 64 × 36 in table
Verdict
The only measured difference is Z stroke. Buy the EC-1600ZT if your large castings, valve bodies or mold bases need more than 32 in (813 mm) of reach from the spindle, since its 40 in (1,016 mm) Z avoids refixturing. If your parts fit within 32 in, the standard EC-1600 does the same work with the same spindle and tool changer at a list price of US$322,995 against US$376,995.
