Summary

The Kellenberger SP51 is a CNC turning center designed for high-precision two-axis machining and complex multi-tasking operations, capable of producing parts with high surface quality and geometric accuracy. It features advanced control systems, dynamic spindle balancing, and integrated spindle motor technology to enable single-setup machining and minimal human intervention. The SP51 is suitable for both delicate part handling and demanding production environments where precision and repeatability are critical.

Key Capabilities

• Supports fully automated, multi-task turning operations with FANUC 31i TB control
• Delivers high surface quality (0.2 μm or better) and maintains total diameter deviation within 3 μm
• High machine rigidity validated by finite element analysis
• Dynamic balancing of spindle and drive motor for reduced vibration and enhanced surface finish
• Integrated spindle motor eliminates belt drives, improving spindle response and accuracy
• High repeatability of axes (0.76 μm) and digital linear glass scales for precise positioning
• 12-station turret (BMT-55) for flexible tooling and complex parts
• Capable of both turning and drilling cycles, with support for chamfering, radiusing, and circle interpolation
