Advantages
Kern Evo
- Superior surface finish at Ra < 0.1 um achievable vs Ra 0.02 um achievable
- More competitive pricing at $400,000 - $650,000 compared to $1,200,000 - $1,800,000+
- 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
Kern Pyramid Nano
- Greater x travel of 500 mm (19.7 in) accommodates larger workpieces
- Greater y travel of 500 mm (19.7 in) accommodates larger workpieces
- Greater z travel of 300 mm (11.8 in) accommodates larger workpieces
- More spindle power at 8.5 kW (11.4 hp) for aggressive material removal in harder materials
- Larger tool magazine with Up to 209 tools capacity reduces manual tool changes on complex parts
Verdict
The Kern Pyramid Nano 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.
