Surface Roughness Comparator
Surface roughness comparator RU130
- Equivalent to SPI30-695-1
- This set consists of 30 comparison specimens, covering six of the most commonly-
used machining methods: 6 cylindrically turned, 6 end- milled, 6 horizontally milled, 6 surface-ground, 3 lapped, 3 reamed/drilled.
Used for:
- 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 ISOย 8503 - estimating surface roughness prior to accurate measurement by a stylus instrument, as recommended in BS EN ISOย 4288,
- checking the seriousness of damage to parts caused by nicks, dents and scratches
- checking reconditioned ship propeller blades
