Surface finish comparator plates roughness standards sets
Application:
- Checking roughness of turned, milled, ground, reamed, polished or lapped parts during machining
- Checking the roughness of spark-eroded surfaces as described in the VDI 3400 Guideline
- Checking the roughness of steel surfaces which have been prepared for painting by blast-cleaning, as outlined in ISO 8503
- Estimating surface roughness prior to accurate measurement by a stylus instrument, as recommended
in BS EN ISO 4288, eg. - Checking the seriousness of damage to parts caused by nicks, dents and scratches
- Checking reconditioned ship propeller blades
- Made from 100% Nickel
Including:
6 turned, 6 end-milled, 6 horizontally milled, 6 surface-ground, 3 lapped, 3 reamed/drilled. A label gives the Ra and Rz values of each specimen in both metric and imperial units
