Overview
The Haas UMC-750 sits in the middle of the UMC range: 30 × 20 × 20 in (762 × 508 × 508 mm) of travel, a 19.7 in (500 mm) platter and a 660 lb (300 kg) load limit on a two-axis trunnion. The spindle is the 30 hp (22.4 kW), 8,100 rpm inline direct-drive unit, and the starting price Haas lists is US$192,995.
The UMC-500 below it has 24 × 16 × 16 in (610 × 406 × 406 mm) and a 15.7 in (400 mm) platter for 500 lb (226.8 kg). The UMC-1000 above has 40 × 25 × 25 in (1,016 × 635 × 635 mm) and a 25 in (635 mm) platter for 1,000 lb (454 kg). All three share the spindle rating, the 650 ipm (16.5 m/min) cutting feed and the 900 ipm (22.9 m/min) rapids, so the decision between them is about part size and weight, not cutting performance.
On this size the tilt axis is the stronger of the two. B has 2,240 ft-lbf (3,037 N·m) of torque and a 2,000 ft-lbf (2,712 N·m) brake; C has 1,854 ft-lbf (2,514 N·m) and a 900 ft-lbf (1,220 N·m) brake. Both use cycloidal drives and both top out at 50°/sec. Part swing is 27 in (686 mm), well beyond the platter diameter, so the practical limit on a large part is usually whether it clears the spindle head when tilted, with 24 in (610 mm) at most between spindle nose and platter.
Thrust is 3,300 lbf (14,680 N) in X and Y and 4,050 lbf (18,015 N) in Z. The 30+1 side-mount changer accepts tools 12 in (305 mm) long and 12 lb (5.4 kg) in weight and changes in 2.8 s tool-to-tool. The base machine ships at 14,250 lb (6,463.8 kg) on a 168 × 92.5 × 110 in (427 × 235 × 280 cm) pallet and draws 70 A at 220 VAC three-phase or 35 A at 440 VAC.

Frequently Asked Questions
01
Up to 660 lb (300 kg) on a 19.7 in (500 mm) platter, with a maximum part swing of 27 in (686 mm). Linear travels are 30 in (762 mm) in X and 20 in (508 mm) in both Y and Z. The spindle nose is between 4 in (102 mm) and 24 in (610 mm) from the platter, which is the height available for fixture, part and tool together.
02
Decide on part size. The UMC-1000 has 40 × 25 × 25 in (1,016 × 635 × 635 mm) of travel and a 25 in (635 mm) platter rated for 1,000 lb (454 kg), and ships at 15,600 lb (7,077 kg). The UMC-750 covers 30 × 20 × 20 in (762 × 508 × 508 mm) and 660 lb (300 kg). Spindle, feedrates and tool capacity are listed the same.
03
The UMC-750SS is listed at 12,000 rpm with 1,200 ipm (30.5 m/min) rapids and an 833 ipm (21.2 m/min) cutting feedrate. The UMC-750 is listed at 8,100 rpm, 900 ipm (22.9 m/min) and 650 ipm (16.5 m/min). Travels, platter size, the 660 lb (300 kg) load and the 30 hp (22.4 kW) spindle rating are the same.
04
It is 19.7 in (500 mm) in diameter with 7 T-slots. The slots are 0.626 in to 0.63 in (15.9 mm to 16 mm) wide on 2.48 in (63 mm) centres. If the machine is run with a pallet pool, the platter load limit is 200 lb (90.7 kg) in place of 660 lb (300 kg).
05
The base machine is listed at 14,250 lb (6,463.8 kg) on a domestic pallet of 168 × 92.5 × 110 in (427 × 235 × 280 cm) or an export pallet of 174 × 92 × 100 in (442 × 234 × 254 cm). With a conveyor and the 120+1 tool changer the listing is 17,100 lb (7,756 kg) on a 176 × 122.5 × 110 in (447 × 311 × 279 cm) pallet. These are shipping figures, not the installed size.
