High-Accuracy Digital Contour Measurement System for Gears,
Pulleys, and Screws
Surface Roughness Tester Contour Measuring System
The measurable elements of all surfaces include size, shape,
roughness and waviness. Many high-profile components require
analysis of all these elements:
- Dimensions: Surface functional shapes defined by the linear relationship
between radius, angle, distance, and features
- Shape: Deviation from the target shape of the surface (plane, sphere,
cone, etc.), typically caused by machine error
- Roughness: Caused by factors such as cutting tools or machining processes
- Waviness: Non-ideal machine effect caused by vibration, insufficient
rigidity or other unstable factors in the process
