Advantages
OKK HM1000S
- Greater x travel of 1,600 mm (63.0 in) accommodates larger workpieces
- Greater y travel of 1,300 mm (51.2 in) accommodates larger workpieces
- Greater z travel of 1,300 mm (51.2 in) accommodates larger workpieces
- Superior spindle torque at 800 N-m (590 ft-lb) at low range vs 500 N-m (369 ft-lb) at low range
- Larger tool magazine with 60 tools (90 or 120 optional) capacity reduces manual tool changes on complex parts
OKK HM6000S
- Faster rapid traverse at 48 m/min (1,890 ipm) reduces non-cutting time between operations
- Tighter positioning accuracy at +/-4.0 um for precision-critical work
- Tighter repeatability at +/-2.0 um for precision-critical work
- Superior spindle speed at 10,000 rpm (2-speed gear head) vs 8,000 rpm (2-speed gear head)
- More competitive pricing at $350,000 - $500,000 compared to $500,000 - $750,000
Verdict
The OKK HM1000S holds a spec advantage in this comparison, but the right choice depends on your shop's priorities. If the OKK HM1000S's strengths in areas like X Travel and Y Travel align with your work, it's the clear pick. The OKK HM6000S may still win on dealer proximity, existing tooling compatibility, or specific features that matter most to your applications. Request quotes from both dealers and, if possible, run your actual parts on each machine before deciding.
