Advantages
GF Mikron HSM 500 GRAPHITE
- Higher maximum spindle speed of 42,000 RPM enables faster cutting on aluminum and non-ferrous materials
- Faster rapid traverse at 42 m/min (1,654 ipm) reduces non-cutting time between operations
- Superior machine weight at 5,800 kg (12,787 lb) vs 4,800 kg (10,582 lb)
Okuma GENOS M460-VE
- Greater x travel of 762 mm (30.0 in) accommodates larger workpieces
- Greater y travel of 460 mm (18.1 in) accommodates larger workpieces
- Greater z travel of 460 mm (18.1 in) accommodates larger workpieces
- More spindle power at 22/18.5 kW (30/25 hp) for aggressive material removal in harder materials
- Larger tool magazine with 32 (arm-type ATC) capacity reduces manual tool changes on complex parts
Verdict
The Okuma GENOS M460-VE edges ahead on specifications in this comparison, particularly in X Travel and Y Travel. However, the GF Mikron HSM 500 GRAPHITE remains competitive and may be the better choice depending on price, dealer support in your area, or specific workholding and tooling considerations. Both are capable machines — the best decision comes from running your actual parts and evaluating total cost of ownership including tooling, training, and service.
