Rubert 317 | Microsurf Roughness Comparator – Flat Lapping | Ra 0.025–0.2 µm, N1–N4, 4 + 4 Patches
Part Number : 317
Covering Ra 0.025–0.2 µm, with Rz 0.4–1.0 µm for the criss-cross lay and 0.4–1.6 µm for the parallel lay (N1–N4) across 4 + 4 patches, the Rubert 317 is the Microsurf comparator for flat-lapped faces with criss-cross and parallel lay. As part of the lightweight 300 series it is designed for office and design use rather than the workshop, and it is packed in a plastic wallet with an instruction card. For workshop use, the heavy-duty Series 100 equivalent is the 117.
