Machine Comparison
Kern Evo vs Kern Micro HD
Kern Microtechnik vs Kern Microtechnik · 5-Axis Machining Centers
Summary
The Kern Evo and the Kern Micro HD are two compact 5-axis machining centers from Kern Microtechnik with work envelopes of nearly the same size. The headline difference in the published figures is tool-change speed: the Kern Micro HD is listed at < 4.5 s chip-to-chip against 5.5 s for the Kern Evo.
The travels trade places. The Kern Micro HD has the longer X axis, 350 mm against 300 mm, while the Kern Evo has the longer Y axis, 280 mm against 220 mm. Both have 250 mm of Z travel. The Kern Evo runs a Heidenhain iTNC 530 control and the Kern Micro HD a Heidenhain TNC640. The table for this pair, built from authorized distributors' pages, holds only these rows.

Advantages
Kern Evo
- 280 mm of Y travel against 220 mm
- Suits micro-milling with small tools in shops with limited floor space
Kern Micro HD
- 350 mm of X travel against 300 mm
- < 4.5 s chip-to-chip against 5.5 s
- Suits parts with many tool changes and long unattended runs
Verdict
On the published rows the choice comes down to part shape and tool changes. Pick the Kern Evo when the part needs depth in Y, 280 mm against 220 mm. Pick the Kern Micro HD when the part is longer in X, 350 mm against 300 mm, or when the program has many tool changes and < 4.5 s chip-to-chip against 5.5 s shortens the cycle. Z travel is the same 250 mm on both, so it decides nothing.
