Kern Evo

The Kern Evo is Kern Microtechnik's entry into the high-precision 5-axis segment, designed to deliver the brand's hallmark accuracy at a more accessible price point than the Micro HD or Pyramid Nano. With 300 x 280 x 250 mm of travel and positioning accuracy in the low single-digit micron range, the Evo targets small-part precision work in medical, dental, watchmaking, and electronics applications where conventional machining centers cannot hold tight enough tolerances.

Kern builds the Evo on the same polymer concrete base philosophy used across the entire lineup, providing the vibration damping that separates Kern machines from competitors using cast iron or welded steel structures. The HSK-E32 spindle runs up to 50,000 RPM and accepts small-diameter tools suitable for micromachining operations. While the Evo uses precision linear guides rather than the full hydrostatic system found on the Micro HD, the combination of the mineral cast base and precision preloaded guides still delivers accuracy levels that most shops associate with machines costing significantly more.

The trunnion-style 5-axis configuration provides full simultaneous 5-axis motion through a compact rotary tilting table with direct-drive motors. The table accepts workpieces up to approximately 200 mm diameter, making it well-suited for the small medical implants, watch components, and connector molds that represent Kern's core customer base. Tool storage accommodates up to 90 positions in the standard configuration.

The Evo runs on a Heidenhain TNC 640 control, giving operators the same programming environment used on the larger Kern machines. For shops stepping up from 3-axis or lower-precision 5-axis equipment, the Evo provides a genuine path into micro-precision territory without the seven-figure investment required for the Micro HD or Pyramid Nano. Surface finishes below Ra 0.1 um are achievable with proper tooling and cutting strategies.
