Haas VF-2TR

The Haas VF-2TR is a VF-2 fitted with a two-axis trunnion, which adds A and B rotary axes to the 30 × 16 × 20 in (762 × 406 × 508 mm) linear travels and makes it a five-axis machine. The trunnion platter is 6.3 in (160 mm) in diameter. That one figure tells you who the machine is for: small, complex parts.

The trunnion limits are tighter than the frame around it. Haas allows 80 lb (36.3 kg) on the platter and lists maximum part swing as 18 in (445 mm). Swing describes clearance, not capacity, since a part that large would still have to come in under 80 lb with its fixture. The platter has 6 standard T-slots 0.625 in (16 mm) wide and a pilot bore 4.63 in (117.6 mm) deep for locating fixtures. Both rotary axes rapid at 80 °/sec and cut at up to 33 °/sec.

Height is the dimension that runs out first. The spindle nose sits between 5.4 in (137 mm) and 14.6 in (371 mm) above the platter, compared with 4 in (102 mm) to 24 in (610 mm) above the bare table, so a tall part and a long tool together need checking in a simulation or layout before the job is quoted. Haas still lists the 36 × 14 in (914 × 356 mm) T-slot table and its 3,000 lb (1,361 kg) rating for this model.

The cutting hardware is the VF-2's: an 8,100 rpm inline direct-drive spindle rated 30 hp (22.4 kW) and 90 ft-lbf (122 N·m) at 2,000 rpm, with 250 ft-lbf (339 N·m) at 450 rpm available from an optional gearbox. Where the VF-2 has 20 tools, the VF-2TR has a 30+1 side-mount changer that takes 2.8 s tool-to-tool and 3.6 s chip-to-chip. It ships at 8,300 lb (3,765 kg) against 7,800 lb (3,539 kg) for the VF-2, and Haas's starting price is US$160,995.
