Summary

The Kellenberger T1000 is a CNC modular cylindrical grinding machine designed for precision external grinding of medium to large batches. It delivers high-precision grinding outcomes for prismatic components, bar stock, and complex shaft-type parts, and supports synchronous machining and integration of additional operations. Differentiating features include hydrostatic guides, modular automation options, and the capability to grind directly from hardened bar stock.

Key Capabilities

• Precision external cylindrical grinding with synchronous machining support
• Capable of prism and bar grinding, including finish-grinding from hardened bar material
• Hydrostatic guideways for increased accuracy and surface finish
• Fast part changeover and retooling to support production flexibility
• Modular automation integration from basic handling to autonomous cells
• Burr-free grinding for producing sharp and clean edges
• Configurable for water or oil-based operation
• SIEMENS SINUMERIK ONE CNC control with process-optimized operation and measurement integration
