Haas UMC-1000SS vs Haas UMC-1250
Haas Automation vs Haas Automation · 5-Axis Machining Centers
Summary
The Haas UMC-1000SS and Haas UMC-1250 are 5-axis machining centers with the same 30 hp (22.4 kW) spindle rating, 90 ft-lbf @ 2,000 rpm of torque and a 30+1 tool changer. The UMC-1000SS is built for speed; the UMC-1250 is built for size.
The UMC-1250 has 50 in (1,270 mm) of X travel against 40 in (1,016 mm), 30 in (762 mm) of Y against 25 in (635 mm), and 28 in (711 mm) of Z against 25 in (635 mm). The UMC-1000SS spins to 12,000 rpm against 8,100 rpm, changes tools in 1.8 s against 2.8 s, runs 2.4 s chip-to-chip against 3.6 s and rapids at 1,200 ipm (30.5 m/min) against 900 ipm (22.9 m/min). Haas lists the UMC-1000SS at US$286,995 and the UMC-1250 at US$311,995.

Advantages
Haas UMC-1000SS
- 12,000 rpm spindle against 8,100 rpm
- 2.4 s chip-to-chip against 3.6 s
- 1,200 ipm (30.5 m/min) rapids against 900 ipm (22.9 m/min)
- Lower published list price, US$286,995 against US$311,995
Haas UMC-1250
- 50 in (1,270 mm) of X travel against 40 in (1,016 mm)
- 30 in (762 mm) of Y travel against 25 in (635 mm)
- 28 in (711 mm) of Z travel against 25 in (635 mm)
Verdict
Choose the UMC-1000SS for high-throughput 5-axis production of aluminum structures, impellers and housings that fit 40 in (1,016 mm) of X travel, where 12,000 rpm and 2.4 s chip-to-chip time cut cycle time. Choose the UMC-1250 for oversized parts that exceed that envelope, such as large housings, manifolds and mold cores, where 50 in (1,270 mm) of X and 30 in (762 mm) of Y travel matter more than speed.
