Summary

The Kellenberger U300 is a 5-axis CNC machine designed for high-precision internal and external cylindrical grinding of advanced materials. It enables the consolidation of complex grinding operations—including ID, OD, bevel, face, radius, and small feature grinding—in a single setup with multi-spindle support and automatic tool change capabilities. Notable technical features include hydrostatic swiveling B-axes, multi-axis interpolation for complex part geometries, and compatibility with advanced CNC controls.

Key Capabilities
