Machine Comparison
Kern Micro HD vs Kern Micro Vario
Kern Microtechnik vs Kern Microtechnik · 5-Axis Machining Centers
Summary
The Kern Micro HD and the Kern Micro Vario are two 5-axis machining centers from Kern Microtechnik with the same work envelope. Both travel 350 mm in X, 220 mm in Y and 250 mm in Z, and both run the Heidenhain TNC 640 control.
The table for this pair is short: the authorized distributors' pages behind it publish few comparable figures, and every row that can be compared is a tie. On these rows neither machine is stronger. The difference lies in the work each is aimed at. The Kern Micro HD is aimed at short 5-axis finishing moves and parts with many tool changes, the Kern Micro Vario at micro-machining with an air-bearing spindle and at small round parts.
Specifications Comparison
| Specification | Kern Micro HD | Kern Micro Vario |
|---|---|---|
| X-Axis Travel | 350 mm | 350 mm |
| Y-Axis Travel | 220 mm | 220 mm |
| Z-Axis Travel | 250 mm | 250 mm |
| Control | Heidenhain TNC640 | Heidenhain TNC 640 |
Advantages
Kern Micro HD
- Aimed at short 5-axis finishing moves, where axis acceleration sets the cycle time
- Aimed at parts with many tool changes and long unattended runs
Kern Micro Vario
- Aimed at micro-machining with an air-bearing spindle
- Aimed at small round parts and tightly toleranced positioning work
Verdict
The published rows cannot separate these two: 350 x 220 x 250 mm of travel and a Heidenhain TNC 640 control on both, so any part that fits one fits the other. Choose on the points the table does not cover, which are spindle options, magazine size and automation, and ask for both data sheets. As a guide, the Kern Micro HD is aimed at fast finishing with frequent tool changes, the Kern Micro Vario at micro-machining.
