Haas VF-1YT

The Haas VF-1YT is a 40-taper vertical machining center with equal travel on all three axes: 20 × 20 × 20 in (508 × 508 × 508 mm). The extended Y is what separates it from the VF-1, which has 16 in (406 mm) of Y and a 26 × 14 in (660 × 356 mm) table. Here the table is 26 × 18 in (660 × 457 mm).

A table that is nearly as deep as it is long changes what can be fixtured. Square plates, round blanks and rotary-table setups sit inside the travel without the part hanging off the front, and the 18 in (457 mm) table depth gives room for a second row of small vises that the 14 in (356 mm) table of the VF-1 lacks. The 3,000 lb (1,361 kg) table load is high for a table of this area, so fixture weight is rarely the constraint. The spindle nose runs from 4 in (102 mm) to 24 in (610 mm) above the table.

The listed equipment differs from the VF-1 in more than Y. Spindle speed is 10,000 rpm against 8,100 rpm on the VF-1, with the drive given as direct speed, belt drive. The rating is 30 hp (22.4 kW) with 90 ft-lbf (122 N·m) at 2,000 rpm, and the table also carries an optional-gearbox figure of 250 ft-lbf (339 N·m) at 450 rpm. The tool changer is a 30+1 side-mount type where the VF-1 has 20 tools. It changes in 2.8 s tool-to-tool and 3.6 s chip-to-chip.

Tool diameter depends on how the magazine is loaded: a tool can be 2.5 in (64 mm) in diameter with the magazine full, or 5 in (127 mm) if the pockets either side are left empty, and up to 12 lb (5.4 kg). Feedrates are 650 ipm (16.5 m/min) cutting and 1,000 ipm (25.4 m/min) rapid, with 2,550 lbf (11,343 N) of thrust on X and Y and 4,200 lbf (18,683 N) on Z. The machine ships at 8,000 lb (3,629 kg). Haas's table for this model gives no electrical figures, so ask for the supply requirement when requesting a quote.
