Each is processed to a specified range of surface roughness by grinding or lapping.
| From left to right, from top to bottom | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Aim roughness | Ra below 0.1μm | Ra 0.1μm | Ra 0.2μm | Ra 0.4μm | Ra 0.6 | Ra 0.7 | Ra 1.8 |
| Actual value | Ra 0.006μm | Ra 0.130μm | Ra 0.244μm | Ra 0.376μm | Ra 0.553μm | Ra 0.705μm | Ra 1.83μm |
In addition, there are differences in materials and supplied materials,
We have a track record of managing rough surface roughness and specified parameters (Rz, etc.) that cannot be produced by grinding.
