Advantages
Haas EC-500/50
- Lower published list price, US$349,995 against US$447,995
- Same 340 ft-lbf (460 N·m) spindle and 6.3 s chip-to-chip in a smaller machine
Haas EC-630
- 630 × 630 mm pallets against 500 × 500 mm
- 37 in (940 mm) of Y travel against 25 in (635 mm)
- 40 in (1,016 mm) of X and Z travel against 32 in (813 mm) and 28 in (711 mm)
Verdict
Both cut steel and cast iron with the same 50-taper spindle at the same pace, so buy on part size. The EC-500/50 suits medium-to-high volume ferrous parts and tombstones that fit a 500 × 500 mm pallet, at US$349,995. The EC-630 is the step up for larger blocks and heavy components that need a 630 × 630 mm pallet and 40 in (1,016 mm) of X and Z travel.
