- Lower published list price: US$83,995 against US$101,995
- Lighter machine to rig and place: 7,800 lb (3,539 kg) against 11,720 lb (5,316 kg)
Haas VF-3SS
- 40 in (1,016 mm) of X travel against 30 in (762 mm)
- 20 in (508 mm) of Y and 25 in (635 mm) of Z against 16 in (406 mm) and 20 in (508 mm)
- 48 × 18 in (1,219 × 457 mm) table against 36 × 14 in (914 × 356 mm)
- 1,750 lb (794 kg) table rating against 1,500 lb (680 kg)
Verdict
Cycle times will be the same on either machine, so decide by what has to fit on the table. The Haas VF-3SS suits production with several vises or a long fixture plate on its 48 in table, or parts beyond 30 in long. The Haas VF-2SS Super Speed VMC runs the same aluminum work at the same 12,000 rpm on parts inside 30 x 16 x 20 in, at a list price of US$83,995. Both have light table ratings, so neither is the machine for heavy fixtures.
