Advantages
Kern Evo
- Larger tool magazine with Up to 90 tools capacity reduces manual tool changes on complex parts
- More competitive pricing at $400,000 - $650,000 compared to $450,000 - $650,000
- Backed by Kern Microtechnik's dealer and service network for parts and support
- Medical and dental device manufacturers producing small implants, prosthetics, and surgical tools to tight tolerances
Makino a500iR
- Greater x travel of 560 mm (22.0 in) accommodates larger workpieces
- Greater y travel of 640 mm (25.2 in) accommodates larger workpieces
- Greater z travel of 640 mm (25.2 in) accommodates larger workpieces
- More spindle power at 22 kW (29.5 hp) continuous for aggressive material removal in harder materials
- Tighter positioning accuracy at ±0.003 mm (±0.00012 in) for precision-critical work
Verdict
The Makino a500iR edges ahead on specifications in this comparison, particularly in X Travel and Y Travel. However, the Kern Evo 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.
