Overview
The Haas EC-1700ZT is a large horizontal machining centre built around a 1,626 x 914 mm (64 x 36 in) table that carries 4,536 kg (10,000 lb). Travels are 1,727 x 1,270 x 1,270 mm (68 x 50 x 50 in), and the ZT designation marks the integrated rotary trunnion arrangement that adds simultaneous axis capability to the horizontal format.
Horizontal machines earn their place through chip evacuation and pallet-side setup, and at this size that matters more than usual. Cutting on a horizontal spindle drops chips away from the part instead of packing them into a pocket, which on long cycles in cast iron or steel is the difference between running unattended and standing there with an air gun.
The spindle is a 30 hp unit reaching 7,500 RPM with 460 Nm (340 ft-lbf) at 700 RPM, feeding a 50+1 tool changer. That tool capacity is the largest offered across the EC line and reflects the reality that big horizontal work tends to involve a lot of operations.
US$416,995 buys it. The cross-shop is usually a Doosan NHP or an Okuma MA-series horizontal, both of which bring more spindle speed and, in Okuma's case, better thermal compensation, at a higher price. Where the Haas wins is total cost and the fact that a shop already running Haas verticals gets one control and one service relationship.

Strengths & Limitations
Strengths
- 4,536 kg (10,000 lb) table load is the highest in the Haas horizontal range
- 50+1 tool capacity supports long multi-operation cycles without tool swapping
- Horizontal spindle orientation clears chips away from the cut, which suits long unattended runs
- 1,270 mm (50 in) of both Y and Z gives genuine cube capacity rather than a shallow envelope
- 15.2 m/min (600 ipm) rapids are faster than the large VM verticals
- Integrated trunnion adds rotary capability without a separate fourth-axis purchase
Limitations
- 7,500 RPM spindle ceiling is low against Doosan and Okuma horizontals in the same class
- 30 hp is modest for a machine with a 10,000 lb table
- Thermal compensation is less developed than Okuma's on comparable horizontal machines
- Large horizontal machines carry high installation and foundation costs
- Pallet handling and fixturing at this scale require investment beyond the machine itself

Frequently Asked Questions
01
Haas lists US$416,995 as of August 2026. Tombstones, fixturing and a suitable chip and coolant package generally push a working installation past US$470,000.
02
Chip evacuation and multi-face access. Chips fall away from the cut rather than collecting in pockets, which matters on long cycles in cast iron and steel, and tombstone fixturing lets you machine several faces without re-setting.
03
Both generally offer higher spindle speeds and, for Okuma, better thermal compensation, at a higher price. The Haas case is cost, a familiar control, and a dense dealer network.
04
It indicates the integrated rotary trunnion configuration, which adds simultaneous rotary capability to the horizontal platform rather than requiring a separate indexer.
05
A rated foundation, three-phase power, and crane access for tombstone and fixture loading. At this table capacity, part handling infrastructure is as much of a planning item as the machine itself.
