Surface Roughness and Contour Tester for Articulated Arm Bearings
The SPR1000 Series Surface Roughness Contour Tester is a precision measurement system designed for comprehensive surface analysis of industrial components including articulated arm bearings, optical grade germanium crystals, seal rings, and turbo seals.
Surface Measurement Fundamentals
All surfaces can be measured across four key elements that define their functional characteristics:
- Dimensions: Linear relationships between radius, angle, distance, and surface features
- Shape: Deviation from target geometry (plane, sphere, cone) typically caused by machine error
- Roughness: Surface texture resulting from cutting tools or machining processes
- Waviness: Non-ideal machine effects from vibration, insufficient rigidity, or process instability
SPR1000 Series Characteristics
Standard configuration with optimal cost-efficiency. Features dual sensor technology combining digital contour sensing with inductive roughness measurement for comprehensive surface analysis in a single machine.
