Overview
The Haas UMC-1250/50 puts a 50-taper spindle on the UMC-1250 envelope: 60 hp (44.7 kW), 170 ft-lbf (230 N·m) at 1,800 rpm and a 7,500 rpm top speed, in CT or BT 50. Travels stay at 50 × 30 × 28 in (1,270 × 762 × 711 mm), and the 30 in (762 mm) platter carries 1,000 lb (454 kg).
Against the 40-taper UMC-1250, which has 30 hp (22.4 kW) and 90 ft-lbf (122 N·m) at 2,000 rpm, that is twice the power and about 89% more torque. The larger taper also changes what can go in the magazine. A tool may be 4 in (102 mm) in diameter with every pocket full and 7 in (178 mm) with the neighbouring pockets empty, up to 16 in (406 mm) long and 30 lb (13.6 kg). That opens the machine to large face mills and long boring bars.
The bigger spindle asks for more in return. Tool changes take 4.2 s tool-to-tool and 6.3 s chip-to-chip, so jobs made of many short operations lose time at every change. The electrical supply is 105 A at 220 VAC or 53 A at 440 VAC, three-phase, which is worth checking against the shop's service before ordering. The axes behind the spindle have 3,300 lbf (14,680 N) of thrust in X and Y and 4,050 lbf (18,015 N) in Z, and the rotary axes hold with a 2,000 ft-lbf (2,712 N·m) brake on B and 900 ft-lbf (1,220 N·m) on C. With a 7 in cutter working near the edge of the platter, the C brake is the figure to respect.
The spindle is inline direct-drive and air cooled, with air/oil injection bearing lubrication. The table shows no gearbox figure, so 170 ft-lbf at 1,800 rpm is the whole torque story. Buyers who want this taper at higher speed should look at the UMC-1250SS-50, which reaches 12,000 rpm with 140 ft-lbf (189.8 N·m) at 2,200 rpm. Haas lists a starting price of US$356,995 and a shipping weight of 18,820 lb (8,536 kg).

Strengths & Limitations
Strengths
- 60 hp (44.7 kW) CT or BT 50 spindle with 170 ft-lbf (230 N·m) at 1,800 rpm
- Takes tools up to 30 lb (13.6 kg), 16 in (406 mm) long and 7 in (178 mm) in diameter with adjacent pockets empty
- Same 50 × 30 × 28 in (1,270 × 762 × 711 mm) travels and 1,000 lb (454 kg) platter load as the UMC-1250
- B axis tilts from +120° to -35° with 2,240 ft-lbf (3,037 N·m) of torque
- Z-axis thrust of 4,050 lbf (18,015 N) for drilling and boring with large tools
Limitations
- Tool changes are slow at 4.2 s tool-to-tool and 6.3 s chip-to-chip
- Needs 105 A at 220 VAC or 53 A at 440 VAC three-phase
- Top speed is 7,500 rpm; the UMC-1250SS-50 runs the same taper to 12,000 rpm
- Rotary axes are limited to 50°/sec, and the C-axis brake holds 900 ft-lbf (1,220 N·m)
- The table shows no gearbox, so torque peaks at 1,800 rpm with nothing more available at lower speed

Frequently Asked Questions
01
A larger, stronger spindle. The UMC-1250 has a 30 hp (22.4 kW) spindle with 90 ft-lbf (122 N·m) at 2,000 rpm, an 8,100 rpm top speed and CT40, BT40 or HSK-A63 tooling. The UMC-1250/50 has 60 hp (44.7 kW), 170 ft-lbf (230 N·m) at 1,800 rpm, 7,500 rpm and CT or BT 50 tooling. Travels, platter size and load, feedrates and the listed shipping weight are the same on both.
02
Up to 30 lb (13.6 kg) and 16 in (406 mm) long. Diameter is 4 in (102 mm) when the 30+1 magazine is full and 7 in (178 mm) when the pockets on either side are left empty. Remember that tool length comes out of the 32 in (813 mm) maximum distance between spindle nose and platter.
03
They share the taper and the 60 hp (44.7 kW) rating but are tuned differently. The UMC-1250/50 gives 170 ft-lbf (230 N·m) at 1,800 rpm and stops at 7,500 rpm, with 650 ipm (16.5 m/min) cutting feed. The UMC-1250SS-50 gives 140 ft-lbf (189.8 N·m) at 2,200 rpm, runs to 12,000 rpm and feeds at 833 ipm (21.2 m/min). Choose on whether the work is mostly heavy roughing or a mix that includes high-speed finishing.
04
Three-phase power at 220 VAC and 105 A, or at 440 VAC and 53 A. Air demand is 4 scfm at 100 psi (113 L/min at 6.9 bar) with an 80 psi (5.5 bar) minimum supply pressure, through a 3/8 in hose and coupler.
05
Not in the listed figures. Travels are 50 × 30 × 28 in (1,270 × 762 × 711 mm), the spindle nose is 4 in (102 mm) to 32 in (813 mm) from the platter, part swing is 39 in (991 mm) and platter load is 1,000 lb (454 kg), or 500 lb (226.8 kg) with a pallet pool. Longer 50-taper tools do use more of the available height.
