M307.023 Micrometer for Slot Measurement – 50–75 mm, 0.01 mm graduation (Metav IndustryLine)

A compact micrometer for slot and groove measurement, intended for fine mechanical workshops and quality control tasks where short anvils and high repeatability are required.

• Graduation 0.01 mm
• Accuracy ±0.006 mm
• Ratchet stop for consistent force
• Non-rotating spindle for delicate surfaces

Compact design that suits fine assemblies

The instrument is tailored for narrow and hard-to-reach features: the measuring range 50–75 mm and the small measuring faces (0.75 x 6.5 mm) make it ideal for inspecting slots, grooves and slim components. Classified as Micro (max 10–100 mm), this format prioritises stiffness and minimal lever effect, which reduces bending and improves reproducibility on small parts. The compact frame supports steady handling in bench and inspection‑station environments, delivering technical advantages where larger gauges would be unwieldy.

Mechanical features that improve measurement reliability

Built-in mechanical aids elevate day‑to‑day consistency: the ratchet stop ensures a uniform measuring force across repeated checks, while the non-rotating spindle protects delicate surfaces from scraping and reduces operator‑induced variation. Together with the fine 0.01 mm graduation, these features lower the influence of human factors and support tighter process control. The indicated ±0.006 mm accuracy reflects the instrument’s suitability for shop‑floor quality assurance and precision components.

Practical application, handling and maintenance

Reading is performed on an analogue scale with a 0.01 mm division; users benefit from a direct, low‑maintenance display with immediate tactile feedback. The 0.5 mm spindle pitch provides predictable axial movement per revolution, simplifying coarse positioning during measurement. Typical uses include toolmaking, component inspection and small‑series checks where slot geometry matters. Routine care is limited to clean wiping and occasional lubrication of the spindle; calibration intervals should follow internal quality procedures or customer requirements to maintain traceability.

FAQ

What is the exact measuring range of this micrometer?
The measuring range is 50–75 mm for the M307.023 micrometer (Metav IndustryLine), suitable for narrow slots and grooves.

How precise is the instrument for routine inspection?
This micrometer offers a graduation of 0.01 mm and an indicated accuracy of ±0.006 mm, providing reliable repeatability for shop‑floor quality checks.

Why is the non‑rotating spindle important?
A non‑rotating spindle on the M307.023 prevents surface marking and reduces measurement error on delicate components during groove measurement.

Is the ratchet stop beneficial for repeated measurements?
Yes, the ratchet stop standardises measuring force, improving reproducibility across multiple checks with the Metav IndustryLine micrometer.

Which applications are typical for this instrument?
Common uses include toolmaking, component inspection, small‑series production and any task where concise groove or slot geometry must be verified.

What maintenance does the micrometer require?
Maintenance is minimal: keep measuring faces clean, protect the spindle from debris and apply light lubrication as recommended by standard workshop practice.
