The Keysight/Agilent 55290A Angular Position Measurement Kit is a precision calibration instrument for rotational axes in turning and machining centers. It maintains laser beam alignment during indexing table movements up to 15 mm vertical travel and supports full, partial, or multiple rotation calibrations for tools with limited rotational range. The kit performs C-axis calibration on turning centers and integrates with the Keysight 5530 Laser Calibration System.
Technical Specifications
Indexing Mode (Zero-Reference Measurement)
• Accuracy: 0.5 arc seconds + 0.2% of displayed reading
• Index Step Size (Resolution): 1°
• Range: Multiple rotations or partial arcs
• Maximum Lift: 15 mm
• Required Fixture Travel: 2 mm
Laser Measurement Mode
• Accuracy: 0.2% of displayed reading (improvable through laser optics calibration)
• Range: ±10°
• Setup Travel: +2 mm, −1 mm, or manual adjustment from zero reference
– Key Features
• Accommodates tools unable to achieve full 360° rotation through partial arc measurement capability
• Maintains alignment across significant vertical table travel
• Supports zero-reference indexing with 1° resolution steps
• Documentation and analysis of angular positioning accuracy for machine tool capabilities
• Includes adapter plate and flange for C-axis applications on turning centers
– Typical Applications
• Rotational axis calibration in CNC turning and machining centers
• C-axis positioning verification on multi-axis turning equipment
• Angular accuracy documentation for machine tool capability studies
• Three-dimensional flatness measurement (in conjunction with 55281A Angular Optics Kit)
• Way straightness evaluation
– Compatibility & Integration
The kit integrates with the Keysight 5530 Laser Calibration System and supports legacy Agilent and Hewlett Packard systems: Agilent 5530, Agilent 5529, Hewlett Packard 5529, and Hewlett Packard 5528. Supplemental fixturing available via the 55290A-744 Supplemental Fixturing Kit.
