Haas HDC-3

The Haas HDC-3 is a double-column machining center with 150 × 106 × 39 in (3,810 × 2,692 × 991 mm) of travel, a 60 hp (44.7 kW) 50-taper spindle and a 150 × 64 in (3,810 × 1,626 mm) table that takes 10,000 lb (4,536 kg). Haas lists a starting price of US$892,995.

The spindle is an inline direct-drive unit rated 7,500 rpm and 170 ft-lbf (230 N·m) at 1,800 rpm, in CT or BT 50. Tools come from a 50+1 side-mount changer and can weigh 30 lb (13.6 kg) and reach 16 in (406 mm) in length. Maximum diameter is 4 in (102 mm) with a full magazine and 10 in (254 mm) with the adjacent pockets empty, which is face-mill and boring-bar territory. The VF-12/50, a 50-taper vertical with the same 150 in (3,810 mm) of X, lists 30 hp (22.4 kW) and 340 ft-lbf (460 N·m) at 700 rpm, so the HDC-3 has twice the power but half the peak torque.

What the HDC-3 offers over those verticals is width and height. Y travel is 106 in (2,692 mm) against 32 in (813 mm) on the VF-12/50 and 40 in (1,016 mm) on the VF-14/50, and Z is 39 in (991 mm) against 30 in (762 mm). Haas lists 73.5 in (1,867 mm) between the columns and 51 in (1,295 mm) of clearance under the bridge, and a part has to pass both before the travels matter.

Axis speeds are modest. X rapids and cutting feed are 360 ipm (9.1 m/min), Y rapids are 600 ipm (15.2 m/min) and Z rapids 600 ipm. Thrust is 4,000 lbf (17,793 N) on X and Y and 6,300 lbf (28,024 N) on Z.

Power demand is 105 A at 220 VAC or 53 A at 440 VAC three-phase. The table carries no shipping weight or dimensions for this model, so foundation and rigging data have to come from Haas before the order.
