Optical Flat Set M318.225 – Verification standard for micrometres, 0.1 µm flatness

The Optical Flat Set M318.225 is a precision reference set intended for verification of 0–25 mm micrometres, supplying ultra-flat surfaces for calibration tasks and routine inspection in production and quality departments.

• 0.1 µm flatness accuracy
• Four precision plates 15.62–16.00 mm
• Designed for 0–25 mm micrometre checks

Consistent calibration with measurable accuracy

The set provides a flatness specification of 0.1 µm, making it suitable as a visual and tactile reference when verifying the anvil surfaces of small-capacity micrometres. Supplied as four plates, each plate has a matched nominal thickness (15.62, 15.75, 15.87 and 16.00 mm) so that measurement set-ups can be adapted to different anvil clearances without modifying the instrument under test. The closely controlled parallelism 0.006 mm ensures that measurements taken across a plate remain consistent; this reduces the need for repeat adjustments and supports faster in-process checks.

Designed for shop-floor repeatability and ease of use

Manufactured for routine inspection, these reference surfaces combine ease of handling with workshop durability. The compact dimensions (diameter 30 mm) and a total set mass of 0.5 kg make the set simple to store and deploy at the measurement station. Using matched plate thicknesses reduces handling time because the right reference can be selected quickly for the target micrometre range. For quality teams, the direct benefit is fewer measurement interruptions and a clearer pass/fail decision path during calibration or incoming inspection.

Practical applications and technical advantages

This optical flat set is intended primarily for verification of small micrometres and other contact measuring tools that cover the 0–25 mm range; the plates act as stable references for detecting wear or cumulative error in instrument anvils. In production environments, the set serves as a fast diagnostic aid: by comparing the instrument’s reading against the known plate thicknesses, faults and drift can be identified without lengthy dismantling. The compact format and clear nominal values support straightforward documentation of routine checks and help maintain traceability in quality records.

FAQ

What is the purpose of the optical flat set? The optical flat set M318.225 is designed as a reference standard for verification of 0–25 mm micrometres, supplying ultra-flat surfaces to assess instrument accuracy and detect anvil wear.

How are the plates used in a calibration procedure? Each plate in the set represents a known thickness; by placing a plate between the micrometre anvils and comparing the instrument reading with the plate nominal value, deviations can be identified and recorded for corrective action.

Is the M318.225 suitable for production environments? Yes, the compact design, matched plate thicknesses and 0.1 µm flatness make the set suitable for routine shop-floor checks and quick diagnostic tasks in production and quality departments.
