Surface Comparison Plate Set 2–64 µm Ra, 6‑Piece Polished Grind Reference, RA 63/32/16/8/4/2 - Metav IndustryLine

Take advantage of a compact set that combines clearly graded reference surfaces with workshop practicality: the six reference plates cover from Ra 1.6 µm down to Ra 0.05 µm, enabling fast, reproducible assessments after cylindrical grinding; order directly via Metav Werkzeuge or consult the team for specification matching.

Surface comparison plates "Rundschleifen" — Reference set for cylindrical grinding inspections (Ra 1.6–0.05 µm)

The Surface comparison plates "Rundschleifen" provide calibrated-feel reference surfaces intended for evaluating finish quality and process consistency in cylindrical grinding and related surface-finishing operations.

• Calibrated reference surfaces for finish comparison
• Covers Ra 1.6 to 0.05 µm for fine gradation
• Suitable for cylindrical grinding inspections
• Lightweight set, easy to handle in the workshop

Fast, reliable reference for finish assessment

The set offers a practical way to compare a workpiece against established finish grades, turning subjective judgement into repeatable inspection. Each plate represents a defined surface characteristic so that surface finish deviations become immediately visible and tactile. This speeds up decision-making on process adjustments and reduces scrap rates by providing a direct, low-effort benchmark for visual and touch inspection. The compact format supports quick checks at the machine or on the workshop bench without complex measuring devices.

Graded roughness that maps to machining tolerances

The six grades are specified as Ra 1.6 µm / 0.8 µm / 0.4 µm / 0.2 µm / 0.1 µm / 0.05 µm, corresponding to broader comparative marks listed as 63 / 32 / 16 / 8 / 4 / 2 in the available data. These values cover common ranges encountered in cylindrical grinding and fine turning, enabling differentiation between coarse, standard and fine finishes. The clear gradation allows technicians to correlate surface appearance with machining parameters and to document finish classes in quality records.

Practical design for everyday inspection routines

Supplied as a set of six plates, the reference tools are intentionally lightweight (approx. 0.2 kg) and easy to handle, which supports routine use across several production stations. The set format ensures consistent comparison across shifts and machines, helping to harmonise acceptance criteria without lengthy setup. Because the plates are intended for direct comparison, they are particularly useful where quick go/no-go assessments are required and where metrological instruments are reserved for traceable verification steps.

Efficiency and quality assurance in one solution

Integrating this reference set into standard operating procedures contributes to production stability: quicker in-process checks reduce downtime, and clearer acceptance limits lower dispute risk between production and quality control. The plates are well suited for workshop environments focused on grinding and finishing, offering a pragmatic complement to laboratory measurements. The six reference plates provide a straightforward tool for aligning surface expectations across teams while supporting efficient quality governance.
