Overview

The Haas VF-6SS is the Super Speed version of the VF-6, a large-envelope 40-taper vertical machining center set up for shorter cycle times. Travels are 1,626 mm (64.00 in) in X, 813 mm (32.00 in) in Y and 762 mm (30.00 in) in Z, over a table measuring 1,626 × 711 mm (64.0 × 28.0 in) with five T-slots on 125 mm (4.92 in) centers.

X travel matching table length exactly is the useful detail here: the cutter reaches the full length of what can be clamped, so long fixtures and multi-part setups actually work rather than losing their end stations to reach limits. Table load is 907 kg (2,000 lb), which supports real steel fixturing across that length instead of restricting it to light aluminum plates.

The spindle is an inline direct-drive unit reaching 12,000 rpm at 22.4 kW (30.0 hp) with 122.0 Nm (90.0 ft-lbf) at 2,000 rpm, and accepts CT40, BT40 or HSK-A63 tooling. Direct drive removes the belt between motor and spindle, which is what allows the higher speed ceiling. The torque figure keeps expectations honest: 90 ft-lbf peak is an aluminum-oriented number, and heavy steel roughing should be planned against it rather than against the 30 hp rating. Spindle bearings use air/oil injection and the spindle is liquid cooled, both aimed at holding position through long runs at speed.

Speed shows up in the motion specifications more than anywhere else. Rapids are 30.5 m/min (1,200 ipm) in X and Y and 24.0 m/min (945 ipm) in Z, with maximum cutting feed at 21.2 m/min (833 ipm). Axis thrust is 15,124 N (3,400 lbf) on all three. The side-mount tool changer holds 30+1 tools and swaps them in 2.30 s tool-to-tool, 3.20 s chip-to-chip — on a part with many short operations that difference against a carousel changer compounds quickly.

Tooling limits are Φ64 mm (2.5 in) with a full magazine, Φ127 mm (5.0 in) or Φ152 mm (6.0 in) with adjacent pockets empty, 406 mm (16.00 in) long and 5.4 kg (12.0 lb). At 10,116 kg (22,300 lb) with a 360 L (95 gal) coolant tank, the VF-6SS suits aerospace plate work, large mold components and general job shop work on big parts.

Strengths & Limitations

Strengths

X travel of 1,626 mm (64.00 in) matches table length exactly, so the cutter reaches the full length of what can be clamped and long fixtures keep their end stations
907 kg (2,000 lb) table load supports real steel fixturing across that length rather than restricting it to light aluminum plate
Inline direct-drive spindle to 12,000 rpm at 22.4 kW (30.0 hp), accepting CT40, BT40 or HSK-A63 tooling
Side-mount tool changer holds 30+1 tools and swaps in 2.30 s tool-to-tool, 3.20 s chip-to-chip — a difference that compounds on parts with many short operations
Rapids of 30.5 m/min (1,200 ipm) in X and Y with a 21.2 m/min (833 ipm) maximum cutting feed

Limitations

Peak spindle torque is 122.0 Nm (90.0 ft-lbf) at 2,000 rpm — an aluminum-oriented figure, so heavy steel roughing has to be planned against it rather than against the 30.0 hp rating
Axis thrust is 15,124 N (3,400 lbf) on all three axes, modest relative to the size of the work envelope
Maximum tool weight is 5.4 kg (12.0 lb) and length 406 mm (16.00 in) from the gage line, which excludes heavier long-reach assemblies
Only Φ64 mm (2.5 in) tools fit with a full magazine — Φ127 mm or Φ152 mm cutters require leaving adjacent pockets empty and cost usable capacity
At 10,116 kg (22,300 lb) with a 360 L (95 gal) coolant tank, this is a rigging and floor-loading exercise, not a machine that is simply wheeled into place

Best For

Aerospace plate work needing full-length reach across a long fixture Large mold components and die work inside 1,626 × 813 × 762 mm of travel Multi-part setups and tombstone-style fixturing that use the full 1,626 mm table High-mix job shop work where the 2.30 s tool changes recover real time across many operations Aluminum production at 12,000 rpm where spindle speed rather than low-end torque governs the cut

Frequently Asked Questions

01 What is the working envelope of the VF-6SS?

Travels are 1,626 mm (64.00 in) in X, 813 mm (32.00 in) in Y and 762 mm (30.00 in) in Z, over a table measuring 1,626 × 711 mm (64.0 × 28.0 in) with five T-slots on 125 mm (4.92 in) centers. Spindle nose to table ranges from 102 mm (4.0 in) to 864 mm (34.0 in).

02 Can the VF-6SS cut steel and cast iron?

It can, but the cut has to be sized to the torque rather than the horsepower. Peak spindle torque is 122.0 Nm (90.0 ft-lbf) at 2,000 rpm from a 22.4 kW (30.0 hp) motor, and axis thrust is 15,124 N (3,400 lbf). That favours lighter, faster passes in ferrous material. The 12,000 rpm ceiling shows the machine was set up primarily for aluminum and high-speed work.

03 What makes the SS version different from a standard VF-6?

The Super Speed configuration centres on motion and the spindle. It uses an inline direct-drive spindle reaching 12,000 rpm, rapids of 30.5 m/min (1,200 ipm) in X and Y and 24.0 m/min (945 ipm) in Z, and a side-mount tool changer at 2.30 s tool-to-tool and 3.20 s chip-to-chip. Direct drive removes the belt between motor and spindle, which is what allows the higher speed ceiling.

04 How much can be clamped on the table?

Table load is rated 907 kg (2,000 lb) across a 1,626 × 711 mm surface with five T-slots. Because X travel matches table length exactly at 1,626 mm, the entire table is reachable — long fixtures and multi-part setups do not lose their end stations to travel limits.

05 What are the tooling limits?

Capacity is 30+1 tools in the side-mount changer, in CT40, BT40 or HSK-A63. Maximum tool diameter is 64 mm (2.5 in) with a full magazine, rising to 127 mm (5.0 in) or 152 mm (6.0 in) with adjacent pockets left empty. Tools can be up to 406 mm (16.00 in) from the gage line and 5.4 kg (12.0 lb).

06 What utilities does the VF-6SS require?

Power is 220 VAC 3-phase at 70 A or 440 VAC 3-phase at 35 A. Air demand is 113.0 L/min at 6.9 bar (4 scfm at 100 psi) with a 5.5 bar (80 psi) minimum. The coolant tank holds 360 L (95 gal), and the machine weighs 10,116 kg (22,300 lb).
