Surface Roughness Measurements
Surface roughness measurements with the Mitutoyo SJ-400 instrument.
After every grinding or honing operation, roughness decides whether the surface will hold its oil film: the Ra and Rz values document that the machining was done — and done right.
- Ra 0.28 μm
- Indicative reading (SJ-400)
- Rz 1.5 μm
- Indicative reading (SJ-400)
