Overview
The Haas UMC-400SS takes the UMC-400 and speeds up three things: the spindle goes from 8,100 rpm to 12,000 rpm, rapids from 900 ipm (22.9 m/min) to 1,200 ipm (30.5 m/min), and the cutting feedrate from 650 ipm (16.5 m/min) to 833 ipm (21.2 m/min). The envelope is unchanged at 17 × 11 × 13 in (432 × 279 × 330 mm) over a 9.1 in (230 mm) trunnion platter. Haas lists a starting price of US$132,995.
Spindle power does not rise with the speed. It is still 15 hp (11.2 kW) with 46 ft-lbf (62 N·m) at 1,700 rpm, so the higher top speed helps small end mills, drills and ball-nose finishing tools reach their surface speed; it does not let the machine take a deeper cut. For small parts finished with small cutters, the kind of work a 100 lb (45.4 kg) platter limit invites, that is the useful direction.
Tool changes are quicker as well: 1.8 s tool-to-tool and 2.4 s chip-to-chip from the 30+1 side-mount changer. On parts with many short operations per face, those times and the faster rapids are where the cycle shortens.
Electrical supply is 60 A at 220 VAC three-phase or 30 A at 440 VAC. Part capacity stays small: 100 lb (45.4 kg) on the platter, 14.5 in (368 mm) of swing, and 4 in (102 mm) to 17 in (432 mm) from spindle nose to platter. B tilts from +120° to -45° at 80°/sec and C rotates 360° at 100°/sec. Tools are limited to 2.5 in (64 mm) in diameter with a full magazine and 7 in (178 mm) in length.

Strengths & Limitations
Strengths
- 12,000 rpm inline direct-drive spindle, against 8,100 rpm on the UMC-400
- 1,200 ipm (30.5 m/min) rapids and an 833 ipm (21.2 m/min) cutting feedrate
- Tool changes in 1.8 s tool-to-tool and 2.4 s chip-to-chip
- Same 7,520 lb (3,411 kg) shipping weight as the UMC-400, so the extra speed adds no handling burden
- 360° C axis at 100°/sec with a 9.1 in (230 mm) platter and 14.5 in (368 mm) of part swing
Limitations
- Torque and power are unchanged from the UMC-400 at 46 ft-lbf (62 N·m) and 15 hp (11.2 kW); only the top speed is higher
- Platter load is 100 lb (45.4 kg) including workholding
- Needs a 60 A supply at 220 VAC three-phase, or 30 A at 440 VAC
- Y travel of 11 in (279 mm) and a 7 in (178 mm) tool length limit constrain taller parts

Frequently Asked Questions
01
Higher speeds on the same frame. The UMC-400 is listed at 8,100 rpm, 900 ipm (22.9 m/min) rapids and 650 ipm (16.5 m/min) cutting feed. The UMC-400SS is listed at 12,000 rpm, 1,200 ipm (30.5 m/min) and 833 ipm (21.2 m/min), with tool changes of 1.8 s tool-to-tool. Travels are 17 × 11 × 13 in (432 × 279 × 330 mm) on both.
02
No. Both are listed at 15 hp (11.2 kW) and 46 ft-lbf (62 N·m) at 1,700 rpm, with a CT or BT 40 taper. The UMC-400SS runs to 12,000 rpm and the UMC-400 to 8,100 rpm. Expect the same depth of cut on both, and higher feed with small tools on the SS.
03
B moves at up to 80°/sec with 300 ft-lbf (407 N·m) of torque and a 425 ft-lbf (576 N·m) brake; its travel is +120° to -45°. C rotates 360° at up to 100°/sec with 210 ft-lbf (285 N·m) of torque and a 200 ft-lbf (271 N·m) brake. The platter under them is 9.1 in (230 mm) in diameter.
04
2.5 in (64 mm) in diameter when all 30+1 pockets are in use, and 5 in (127 mm) when the adjacent pockets are left empty. Maximum tool length is 7 in (178 mm). The spindle nose comes no closer than 4 in (102 mm) to the platter, which matters when choosing short holders for small parts.
05
60 A at 220 VAC three-phase, or 30 A at 440 VAC three-phase. Air consumption is 4 scfm at 100 psi (113 L/min at 6.9 bar) and the supply must not fall below 80 psi (5.5 bar). The machine holds 45 gal (170 L) of coolant and ships at 7,520 lb (3,411 kg).
