Overview
The Haas VS-3-5AX is a very large five-axis vertical machine: 150 × 50 × 50 in (3,810 × 1,270 × 1,270 mm) of travel over a 153 × 49 in (3,886 × 1,245 mm) table rated for 10,000 lb (4,536 kg). B tilts ±120° and C rotates from 245° to -245°. The spindle is a 20,000 rpm integral motor unit in HSK-A63, and Haas lists a starting price of US$788,995.
The spindle tells you what the machine is for. It is rated 29 hp (21.6 kW) with 20 ft-lbf (27 N·m) at 7,500 rpm, which is a high-speed, low-torque combination: right for aluminium and other free-cutting materials with small and medium cutters, and for long finishing passes, but not for heavy roughing in steel. Bearings are grease packed and the spindle is liquid cooled.
Axis speeds are modest for the distances involved. X rapids at 360 ipm (9.1 m/min), the same figure as the maximum cutting feedrate, while Y and Z rapid at 600 ipm (15.2 m/min). A reposition along the full X travel takes real time, so nesting operations by location pays off. The rotary axes are quicker, B at 112°/sec and C at 208°/sec. C is not continuous: after 245° in either direction it has to unwind, which a CAM system needs to know about on parts machined all the way round.
Vertical capacity is large. The spindle nose travels from 5 in (127 mm) to 55 in (1,397 mm) above the table, enough for deep moulds, tall fixtures and long weldments. Rotary holding is light by comparison, with brakes of 454 ft-lbf (616 N·m) on B and 442 ft-lbf (600 N·m) on C.
The HDC-3-5AX is the heavy-cutting relative: the same 150 in (3,810 mm) of X and the same table, with a 60 hp (44.7 kW), 6,000 rpm HSK-A100 spindle giving 110 ft-lbf (149 N·m) at 3,000 rpm.

Strengths & Limitations
Strengths
- 150 × 50 × 50 in (3,810 × 1,270 × 1,270 mm) travels with full five-axis motion
- Table of 153 × 49 in (3,886 × 1,245 mm) rated for 10,000 lb (4,536 kg)
- 20,000 rpm liquid-cooled integral spindle in HSK-A63
- Up to 55 in (1,397 mm) from spindle nose to table
- 70+1 side-mount tool changer taking tools up to 30 lb (13.6 kg)
- B tilt of ±120° at 112°/sec and C rotation at 208°/sec
Limitations
- Spindle torque is 20 ft-lbf (27 N·m) at 7,500 rpm, so heavy roughing in steel is outside its range
- X rapid is 360 ipm (9.1 m/min), no faster than the maximum cutting feedrate
- C axis is limited to 245° either way and must unwind; it is not continuous
- Tool change takes 6 s tool-to-tool and 15 s chip-to-chip
- The table gives no machine weight or shipping dimensions, so foundation and rigging have to be planned with Haas

Frequently Asked Questions
01
The spindle is rated 29 hp (21.6 kW) and reaches 20,000 rpm, but torque is 20 ft-lbf (27 N·m) at 7,500 rpm. That profile suits aluminium, plastics, composites and light finishing cuts in harder materials. For heavy cuts in steel on a similar table, the HDC-3-5AX has a 60 hp (44.7 kW) HSK-A100 spindle with 110 ft-lbf (149 N·m) at 3,000 rpm and a 6,000 rpm top speed.
02
B tilts ±120° at up to 112°/sec with 470 ft-lbf (639 N·m) of torque and a 454 ft-lbf (616 N·m) brake. C rotates from 245° to -245° at up to 208°/sec with 285 ft-lbf (386 N·m) of torque and a 442 ft-lbf (600 N·m) brake. Because C stops at 245° each way, tool paths that circle a part need an unwind move.
03
Both have 150 in (3,810 mm) of X, a 153 × 49 in (3,886 × 1,245 mm) table and a 10,000 lb (4,536 kg) load. The HDC-3-5AX has 106 in (2,692 mm) of Y and 43 in (1,092 mm) of Z, a 6,000 rpm HSK-A100 spindle and a 50+1 tool changer. The VS-3-5AX has 50 in (1,270 mm) in both Y and Z, a 20,000 rpm HSK-A63 spindle and a 70+1 changer.
04
The side-mount changer holds 70+1 tools in HSK-A63. Maximum tool diameter is 4 in (102 mm) with a full magazine and 10 in (254 mm) with the adjacent pockets empty, and maximum tool weight is 30 lb (13.6 kg). A change takes 6 s tool-to-tool and 15 s chip-to-chip. The table does not give a maximum tool length.
05
X rapids at 360 ipm (9.1 m/min); Y and Z at 600 ipm (15.2 m/min). Maximum cutting feedrate is 360 ipm (9.1 m/min). Thrust is 4,000 lbf (17,793 N) in X and Y and 6,300 lbf (28,024 N) in Z.
06
Power is 220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A. Compressed air is 4 scfm at 100 psi (113 L/min at 6.9 bar) with a minimum of 80 psi (5.5 bar), through a 3/8 in hose and coupler. Coolant capacity is 95 gal (360 L).
