Surface Roughness Measurement
Practical guidance for Ra, Rz, sampling locations, profilometer setup and finishing line acceptance criteria. Use this page as a focused resource when defining the equipment scope for a complete surface finishing line.
Application Fit
Surface Roughness Measurement should be selected around the surface result, part geometry, production rate and downstream process. In a line project, the machine also has to match loading, unloading, cleaning, drying and inspection requirements.
- Coating preparation
- Sealing surfaces
- Functional friction surfaces
- Cosmetic finish validation
Specification Points
Include these details in the RFQ so suppliers can quote comparable systems and avoid hidden integration gaps.
- Ra and Rz target range
- Cutoff settings
- Measurement direction
- Sampling frequency
- Rework rules
Integration Notes
For a complete production line, the machine should not be specified alone. Confirm part transfer, carryover control, dust or mist collection, utility demand, maintenance access, recipes, alarms and acceptance testing.
Equipment integration
Define this machine as part of the full line.
Share your part geometry, current defect, target surface result and production volume. The response should connect machine selection to line balance, cleaning, drying, inspection and ROI.
