Haas VF-2 vs Haas VF-2SS Super Speed VMC
Haas Automation vs Haas Automation · Vertical Machining Centers
Summary
The VF-2SS is the Super Speed version of the Haas VF-2. Both share the same frame: 30 x 16 x 20 in (762 x 406 x 508 mm) of travel, a 36 × 14 in table, a 30 hp (22.4 kW) spindle and 90 ft-lbf of torque. The differences are all about speed.
The VF-2SS spins to 12,000 rpm against 8,100 rpm, carries 30+1 tools against 20, changes tools in 1.8 s against 4.2 s (2.4 s chip-to-chip against 4.5 s), and rapids at 1,400 ipm (35.6 m/min) against 1,000 ipm. In exchange its rated table load is half that of the VF-2: 1,500 lb (680 kg) against 3,000 lb (1,361 kg). Haas lists the VF-2 at US$70,995 and the VF-2SS at US$83,995.

Advantages
Haas VF-2
- Twice the rated table load: 3,000 lb (1,361 kg) against 1,500 lb (680 kg)
- Lower published list price, US$70,995 against US$83,995
- Same 30 hp (22.4 kW) spindle and 90 ft-lbf torque for steel work
Haas VF-2SS Super Speed VMC
- 12,000 rpm spindle against 8,100 rpm for aluminum and small tools
- 1.8 s tool-to-tool and 2.4 s chip-to-chip against 4.2 s and 4.5 s
- 1,400 ipm (35.6 m/min) rapids against 1,000 ipm (25.4 m/min)
- 30+1 tool side-mount changer against 20 tools
Verdict
Same envelope, different jobs. Buy the VF-2SS for high-mix or high-volume aluminum and non-ferrous parts, where 12,000 rpm and 2.4 s chip-to-chip time pay back the US$13,000 difference in list price. Buy the standard VF-2 for heavier fixtures and steel work that needs its 3,000 lb table rating, or when the faster cycle times would not be used.
