Overview
The Haas EC-1600ZT is a large-frame 50-taper horizontal machining center with a zero-turn (ZT) table configuration. With 1626 x 1270 x 813 mm (64 x 50 x 32 in) of travel and a 1626 x 813 mm (64 x 32 in) table that handles up to 4,536 kg (10,000 lb), this machine is built for big, heavy parts that don't fit on pallet-changing HMCs.
The ZT designation means the table doesn't rotate — it's a fixed horizontal table like you'd find on a large VMC, but with the spindle mounted horizontally. This gives you the chip evacuation and four-sided access advantages of horizontal machining without the complexity and limitations of a rotary table. For shops machining large plates, blocks, and structural components, the ZT configuration is often more practical than a rotating pallet.
The 2-speed gearbox spindle delivers 460 Nm (340 ft-lbf) at 700 RPM with 22.4 kW (30 hp) and a max speed of 7,500 RPM. The 50+1 SMTC handles tools up to 13.6 kg (30 lb), 254 mm (10 in) diameter with adjacent empty, and 508 mm (20 in) max length. Tool-to-tool averages 8.0 seconds and chip-to-chip averages 12.6 seconds — slower than smaller EC machines, reflecting the larger tool changer and heavier tools.
An integrated A-axis with 30 degrees of tilt in each direction and 2,712 Nm (2,000 ft-lbf) of continuous torque is available, enabling angled machining without refixturing. The A-axis handles the full 4,536 kg table load, uses a 500:1 gear ratio, and tilts at 36 degrees per second.
At 13,472 kg (29,700 lb) and a base price around $430,000, the EC-1600ZT delivers large-frame horizontal machining at a fraction of the cost of comparable machines from Mazak, Okuma, or DMG Mori. Specs sourced from Haas Automation published data.

Strengths & Limitations
Strengths
- 4,536 kg (10,000 lb) table load handles the heaviest workpieces in the Haas HMC lineup
- 1626 x 1270 x 813 mm travel envelope accommodates large plates, blocks, and structural components
- Zero-turn table simplifies fixturing for large parts that don't need rotary indexing
- Integrated A-axis with 2,712 Nm continuous torque enables angled machining up to 30 degrees
- 50+1 SMTC with 508 mm max tool length handles long boring bars and extended-reach tools
- Base price around $430K is a fraction of comparable large-frame HMCs from Mazak or Okuma
Limitations
- 12.6 sec chip-to-chip is the slowest of any Haas mill, reflecting the large tool changer
- No pallet changer — the ZT is a single-table machine, limiting unattended operation flexibility
- 30 hp spindle may feel underpowered for a machine this size in heavy roughing applications
- 29,700 lb weight requires substantial floor reinforcement and heavy rigging for installation
- Zero-turn table limits access to parts requiring full rotary indexing — consider the EC-1600 for that

Frequently Asked Questions
01
Base price starts around $430,000. With through-spindle coolant, probing, and other options, expect $480,000-$520,000. The 5-axis EC-1600ZT-5AX starts around $510,000.
02
The EC-1600 is a pallet-changing HMC with a full rotary B-axis. The EC-1600ZT has a fixed zero-turn table with an optional tilt A-axis. The ZT handles 10,000 lb versus the EC-1600's table load, and the ZT's fixed table provides more rigidity for very heavy parts.
03
Zero-turn means the table doesn't rotate. Unlike conventional HMCs with a B-axis rotary table, the EC-1600ZT has a fixed table. The optional A-axis provides tilt capability up to 30 degrees in each direction. This configuration is ideal for large, heavy parts where a rotating table adds unnecessary complexity.
04
The standard EC-1600ZT with A-axis tilt provides 4-axis capability (X, Y, Z plus tilt). For 5-axis, Haas offers the EC-1600ZT-5AX which adds a rotary HRT310 mounted on the tilting table, enabling full simultaneous 5-axis machining.
05
At 13,472 kg before workpieces, plus up to 4,536 kg of part weight, you need reinforced concrete rated for roughly 25,000 kg point loading. Professional rigging and a structural engineering review are essential before installation.
