Advantages
Haas UMC-500
- Lower published list price, US$156,995 against US$192,995
- Lighter at 11,900 lb (5,400 kg) against 14,250 lb (6,463.8 kg)
Haas UMC-750
- 30 in (762 mm) of X travel against 24 in (610 mm)
- 20 in (508 mm) of Y travel against 16 in (406 mm)
- 20 in (508 mm) of Z travel against 16 in (406 mm)
Verdict
Spindle and cycle times are identical, so buy on part size. The UMC-500 suits medium-volume 5-axis parts that fit within 24 in (610 mm) of X travel, such as orthopedic implants and small aerospace parts, at a US$156,995 list price. The UMC-750 suits larger aerospace structures and contoured parts that need 30 in (762 mm) of X and 20 in (508 mm) of Y and Z travel.
