Articulated Arm Contour and Roughness Measurement System for Bearing Surfaces
Surface Roughness Contour Tester
A comprehensive roughness profile measurement analysis system for precision surface evaluation of bearing surfaces and other high-profile components.
Surface Measurement Elements
All surfaces require analysis of these critical elements:
- Dimensions: Surface functional shapes defined by linear relationships between radius, angle, distance, and features
- Shape: Deviation from target surface shape (plane, sphere, cone, etc.), typically caused by machine error
- Roughness: Surface texture variations caused by cutting tools or machining processes
- Waviness: Non-ideal machine effects caused by vibration, insufficient rigidity, or other unstable process factors
SPR1000 Series - Standard Type
Features dual sensor technology with digital contour sensor and inductive standard roughness sensor for combined contour and roughness measurement in one machine.
