Overview

The Haas EC-1600ZT-5AX is the five-axis member of the EC-1600 family. It keeps the 64 × 50 × 40 in (1,626 × 1,270 × 1,016 mm) travels and the 50-taper gearbox spindle of the EC-1600ZT and has two rotary axes: a B axis with +30° to -30° of travel, and a 12.2 in (310 mm) A-axis platter with 360° of travel.

The two rotaries have very different capacities, and that defines the work. The B axis is the heavy one: a 30 in (762 mm) platter rated for 10,000 lb (4,536 kg), 2,000 ft-lbf (2,712 N·m) of rotational torque, a 4,000 ft-lbf (5,423 N·m) brake and a 78 in (1,981 mm) part swing. The A axis is small by comparison. Its platter carries 218 lb (98.9 kg) unsupported or 435 lb (197.3 kg) with support, turns at up to 75°/sec, and has 300 ft-lbf (407 N·m) of torque with a 500 ft-lbf (678 N·m) brake. Its center height is 9 in (228.6 mm). Five-axis work on this machine therefore means parts of a few hundred pounds held on the A platter.

The B travel changes how the machine is used. The EC-1600ZT lists a rotary with 360° of travel; here B is limited to 30° either side, so opposite faces of a table-mounted part cannot be presented by B alone. B moves at 36°/sec, with ± 30 arc-sec indexing accuracy and 15 arc-sec repeatability.

The table is 64 × 32 in (1,626 × 813 mm) with 5 T-slots on 5.7 in (145 mm) centers, narrower than the 64 × 36 in (1,626 × 914 mm) table of the EC-1600ZT. The spindle gives 340 ft-lbf (460 N·m) at 700 rpm and 7,500 rpm from 30 hp (22.4 kW). The 50+1 side-mount changer takes tools to 20 in (508 mm) long and 30 lb (13.6 kg), with 8 s tool-to-tool and 12.6 s chip-to-chip changes. Haas lists a starting price of US$509,995.

Strengths & Limitations

Strengths

Five axes in a 64 × 50 × 40 in (1,626 × 1,270 × 1,016 mm) envelope with a CT or BT 50 spindle

Frequently Asked Questions

01 What are the two rotary axes on the EC-1600ZT-5AX?

A B axis and an A axis. The B axis has a 30 in (762 mm) platter, +30° to -30° of travel, a 10,000 lb (4,536 kg) platter rating and 36°/sec rotation. The A axis, listed as the 5th axis, has a 12.2 in (310 mm) platter with 6 T-slots at 60°, 360° of travel, a maximum speed of 75°/sec and a 9 in (228.6 mm) center height.

02 How heavy a part can be machined in five axes?

The A-axis platter is rated for 218 lb (98.9 kg) unsupported and 435 lb (197.3 kg) with support. Its torque is 300 ft-lbf (407 N·m) and its brake torque 500 ft-lbf (678 N·m). The 10,000 lb (4,536 kg) figure applies to the table and the B-axis platter, not to work carried on the A axis.

03 How does it differ from the EC-1600ZT?

Travels and spindle figures match: 64 × 50 × 40 in (1,626 × 1,270 × 1,016 mm), 30 hp (22.4 kW), 340 ft-lbf (460 N·m) at 700 rpm, 50+1 tools. The EC-1600ZT lists a 64 × 36 in (1,626 × 914 mm) table and a rotary with 360° of travel. The EC-1600ZT-5AX has a 64 × 32 in (1,626 × 813 mm) table, a B axis limited to +30° to -30° and the added 360° A-axis platter.

04 What spindle and tool changer does the EC-1600ZT-5AX have?

A CT or BT 50 spindle on a 2-speed gearbox: 30 hp (22.4 kW), 340 ft-lbf (460 N·m) at 700 rpm and 7,500 rpm. The side-mount changer holds 50+1 tools up to 4 in (102 mm) in diameter, 10 in (254 mm) with adjacent pockets empty, 20 in (508 mm) long and 30 lb (13.6 kg). Tool-to-tool time is 8 s and chip-to-chip 12.6 s.

05 What air and power does the EC-1600ZT-5AX need?

Air consumption is 9 scfm at 100 psi (255 L/min at 6.9 bar). Electrical supply is 220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A. Coolant capacity is 95 gal (360 L). The table gives no machine weight or shipping dimensions for this model, so get those from Haas before planning the installation.
