Nippon RASF Surface Roughness Standard Plate for Face Milling
Made in Japan
Manufacturer: Nippon Kinzoku Denchu
Model: RASF
Feature
- There are two main methods for measuring workpiece surface roughness.
- You can use a mechanical roughness measuring machine for numerical values or visually and tactually compare a pre-made standard surface roughness plate to the workpiece.
Nippon Metal Electrocasting’s ‘Arasa Standard Plate’ is a comparative surface roughness standard plate.
- It involves both visual and tactile comparisons.
- The tactile method appears more accurate, especially when using the fingertip for better sensitivity.
- This approach is widely used in production environments.
