Overview

The Haas VF-12/50 puts a 50-taper geared spindle over a 150 in bed: 150 × 32 × 30 in (3,810 × 813 × 762 mm) of travel, 340 ft-lbf (460 N·m) of torque at 700 rpm and a 7,500 rpm top speed from a 30 hp (22.4 kW) motor. It is a vertical machining center for long work that has to be cut hard, not just reached.

Haas lists a starting price of US$433,995, the same figure it lists for the VF-14/40, so the two are natural alternatives. The VF-14/40 offers 40 in (1,016 mm) of Y with a 40-taper spindle rated 90 ft-lbf (122 N·m) at 2,000 rpm. The VF-12/50 stays at 32 in of Y and puts the difference into the spindle, its 2-speed gearbox and a tool changer for heavier tooling.

That changer holds 30+1 tools in CT or BT 50, each up to 30 lb (13.6 kg) and 16 in (406 mm) long. Diameter is limited to 4 in (102 mm) when every pocket is occupied and 10 in (254 mm) when the pockets either side are empty, which is what lets a large face mill or a boring head live in the magazine. The cost is time: 4.2 s tool to tool and 6.3 s chip to chip. Thrust is 3,400 lbf (15,124 N) on X, 4,100 lbf (18,238 N) on Y and 5,600 lbf (24,910 N) on Z. The spindle is liquid cooled, with air/oil injection to the bearings.

What the long table cannot do is carry unlimited weight. It measures 150 × 28 in (3,810 × 711 mm) and is rated for 4,000 lb (1,814 kg), a figure that heavy steel bar, rail or weldments reach quickly. Quote jobs against that number first, then against the travels. X moves at 360 ipm (9.1 m/min) in rapid, the same as the top cutting feedrate, while Y and Z rapid at 600 ipm (15.2 m/min). The machine ships at 37,200 lb (16,874 kg).

Strengths & Limitations

Strengths

340 ft-lbf (460 N·m) at 700 rpm through a 2-speed gearbox, with a 7,500 rpm top speed
150 in (3,810 mm) of X travel on a table of the same length
Changer carries tools to 30 lb (13.6 kg), and to 10 in (254 mm) in diameter with adjacent pockets empty
Y thrust of 4,100 lbf (18,238 N) and Z thrust of 5,600 lbf (24,910 N)
Liquid-cooled spindle with air/oil injection bearing lubrication

Limitations

Y travel is 32 in (813 mm); Haas lists the VF-14/50 with 40 in (1,016 mm) on the same X and Z
Table load of 4,000 lb (1,814 kg) is low for steel work that fills a 150 in (3,810 mm) table
Tool changes take 4.2 s tool to tool and 6.3 s chip to chip
Spindle power is 30 hp (22.4 kW), the same rating as the VF-12/40, so the gearbox adds torque at low speed, not power
X rapid traverse is 360 ipm (9.1 m/min) over a 150 in (3,810 mm) axis

Best For

Long steel bar, rail and structural sections cut with large tools Heavy drilling and boring along parts up to 150 in (3,810 mm) Face milling long weldments within the 4,000 lb (1,814 kg) table load Jobs that need 50-taper tooling but only 32 in (813 mm) of Y

Frequently Asked Questions

01 Should I choose the VF-12/50 or the VF-12/40?

They share travels, table and table load, so the spindle decides it. The VF-12/40 spindle reaches 8,100 rpm and makes 90 ft-lbf (122 N·m) at 2,000 rpm, while the VF-12/50 makes 340 ft-lbf (460 N·m) at 700 rpm and reaches 7,500 rpm. Both are rated 30 hp (22.4 kW). For large cutters at low speed in steel or iron the VF-12/50 is the stronger fit. For small tools and aluminium, the higher top speed of the VF-12/40 is the more useful figure.

02 How much torque does the VF-12/50 spindle make?

340 ft-lbf (460 N·m) at 700 rpm, from a 30 hp (22.4 kW) motor driving a 2-speed gearbox. Maximum speed is 7,500 rpm. The taper is CT or BT 50, and the spindle is liquid cooled with air/oil injection bearing lubrication.

03 How big and heavy can the tools be on the VF-12/50?

Up to 30 lb (13.6 kg) and 16 in (406 mm) long. With all 30+1 pockets in use the diameter limit is 4 in (102 mm). Leave the adjacent pockets empty and it rises to 10 in (254 mm). Budget 4.2 s tool to tool, or 6.3 s chip to chip, for each change.

04 What is the table like on the VF-12/50?

It is 150 × 28 in (3,810 × 711 mm) with 5 T-slots, 0.626 in to 0.63 in (15.9 mm to 16 mm) wide, on 4.92 in (125 mm) centers. Maximum table load is 4,000 lb (1,814 kg). The spindle nose sits between 5 in (127 mm) and 35 in (889 mm) above the table surface.

05 What are the shipping size and utility requirements?

Shipping weight is 37,200 lb (16,874 kg). The domestic pallet is 343 × 110 × 134 in (871 × 280 × 341 cm) and the export crate 343 × 110 × 137 in (871 × 280 × 348 cm). Supply either 220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A. Air consumption is 4 scfm at 100 psi (113 L/min at 6.9 bar) through a 3/8 in inline hose and coupler, with a minimum of 80 psi (5.5 bar). The coolant tank holds 95 gal (360 L).
