Overview

The Haas EC-1600ZT-5AX is the 5-axis version of the large-frame EC-1600ZT, adding a full B-axis rotary and an HRT310 A-axis to the zero-turn platform. With 1626 x 1270 x 1016 mm (64 x 50 x 40 in) of travel, this is the largest 5-axis capable machine Haas builds — and at a base price around $510,000, it's also one of the most affordable large-frame 5-axis HMCs available from any manufacturer.

The 5AX configuration adds 203 mm (8 in) of Z-travel compared to the standard EC-1600ZT, bringing it to 1016 mm (40 in). The integrated A-axis provides 30 degrees of tilt in each direction with 2,712 Nm (2,000 ft-lbf) of continuous torque and 5,423 Nm (4,000 ft-lbf) of brake torque. The 5th axis comes from an HRT310 rotary with a 310 mm (12.2 in) platter, 360 degrees of travel, 407 Nm (300 ft-lbf) of continuous torque, and 75 degrees per second rapids.

The 1626 x 813 mm (64 x 32 in) table handles up to 4,536 kg (10,000 lb), though the HRT310's unsupported platter capacity is 98.9 kg (218 lb) or 197.3 kg (435 lb) with tailstock support. So while the table can hold enormous weight, 5-axis work through the HRT310 is limited to smaller parts.

The 50-taper 2-speed gearbox spindle delivers 460 Nm (340 ft-lbf) at 700 RPM with 7,500 RPM max speed. The standard 50+1 SMTC handles tools up to 13.6 kg (30 lb) and 254 mm (10 in) diameter with adjacent empty. Tool-to-tool averages 8.0 seconds and chip-to-chip averages 12.6 seconds.

This machine serves a specific niche: shops that need to machine large, heavy parts with 3+2 positioning or limited simultaneous 5-axis capability on the HRT310, all on a single platform with horizontal chip evacuation. It's not competing with purpose-built 5-axis machining centers for small precision parts, but rather providing multi-axis access to large workpieces.

Strengths & Limitations

Strengths

Largest 5-axis capable machine Haas builds, with 64 x 50 x 40 in of travel
4,536 kg (10,000 lb) table load handles massive workpieces for 3+2 and angled machining
Integrated A-axis tilt with 2,712 Nm continuous torque provides rigid angled machining on heavy parts
HRT310 5th axis enables full simultaneous 5-axis on smaller components mounted on the tilting table
Base price around $510K is significantly less than comparable large 5-axis HMCs from competitors
1,016 mm (40 in) Z-travel is 203 mm more than the standard EC-1600ZT

Limitations

HRT310 platter capacity of 98.9 kg unsupported limits 5-axis work to relatively small parts
12.6 sec chip-to-chip is the slowest tool change in the Haas lineup
No pallet changer — single-table design limits unattended operation flexibility
30 hp spindle power is modest for a machine this size and price point
5-axis capability is a bolt-on HRT310, not an integrated purpose-built 5-axis design
29,700 lb weight plus floor space requirements make installation a major project

Best For

Aerospace shops machining large structural components with angled features requiring 5-axis access Energy sector shops running large valve bodies and pump components with compound-angle bores Shops that need 3+2 positioning on heavy parts plus occasional 5-axis work on smaller parts Heavy equipment manufacturers needing multi-angle access to large weldments and castings Job shops taking on oversize 5-axis work that doesn't fit on conventional 5-axis machines Shops wanting one machine that can do 3-axis, 4-axis, and 5-axis work across a range of part sizes

Frequently Asked Questions

01 What does a new Haas EC-1600ZT-5AX cost?

Base price starts around $510,000. With through-spindle coolant, probing, and other options, expect $560,000-$600,000. That's about $80,000 more than the standard EC-1600ZT without 5-axis capability.

02 What's the difference between the EC-1600ZT-5AX and EC-1600ZT?

The 5AX adds an HRT310 rotary for full 5-axis capability and extends Z-travel from 813 mm to 1016 mm. The A-axis tilt and table capacity are the same. Choose the 5AX if you need simultaneous 5-axis or compound-angle machining. The standard ZT is adequate for 4-axis tilt work.

03 Is this a true 5-axis machine?

It supports simultaneous 5-axis machining through the combination of X, Y, Z linear axes plus the A-axis tilt and HRT310 rotary. However, the 5th axis is a bolt-on HRT310 with limited weight capacity (218 lb unsupported), not an integrated 5-axis design. For small precision 5-axis work, consider the Haas UMC-750 or UMC-1000 instead.

04 How heavy can the part be for 5-axis work?

The HRT310 handles 98.9 kg (218 lb) unsupported or 197.3 kg (435 lb) with tailstock support. The full 4,536 kg table capacity is available for 3-axis and 4-axis (tilt) work. The weight limitation only applies when using the HRT310 for 5th-axis rotation.

05 What competitors does the EC-1600ZT-5AX go up against?

In terms of size and capability, it competes with machines like the Mazak HCN-12800 and Okuma MB-10000H, but those machines cost significantly more. The Haas approach of adding 5-axis capability to the EC-1600ZT platform keeps costs much lower than purpose-built large 5-axis HMCs.
