Advantages
Haas UMC-500
- Lower published list price, US$156,995 against US$185,995
- The full 30 hp (22.4 kW) and 90 ft-lbf for steel and stainless, without paying for speed the cut does not use
Haas UMC-500SS
- 12,000 rpm spindle against 8,100 rpm, for aluminum and small tools
- 1.8 s tool-to-tool and 2.4 s chip-to-chip against 2.8 s and 3.6 s
- 1,200 ipm (30.5 m/min) rapids against 900 ipm (22.9 m/min)
Verdict
Buy the Haas UMC-500SS for simultaneous 5-axis contouring and for aluminum parts finished with small tools, where 12,000 rpm and 2.4 s chip-to-chip time pay back the higher list price, US$185,995 against US$156,995. Buy the Haas UMC-500 for five-sided positioning work in steel and stainless, which uses the same 30 hp (22.4 kW) and 90 ft-lbf at spindle speeds both machines reach.
