Three‑point internal micrometer (16–20 mm) — analogue, self‑centring precision

Three‑point internal micrometer for short‑range, high‑precision internal measurements in fine mechanical and general workshop applications.

• Self‑centring three‑point design
• Measuring range 16–20 mm
• Accuracy ±0.005 mm
• Analogue reading 0.005 mm

Repeatable internal measurement where every micron counts

The three‑point internal micrometer combines a mechanically stable frame with a kinematic contact system to reduce operator‑dependent variation. The instrument’s self‑centring principle ensures the measuring anvils align automatically in bore centres, which improves repeatability and shortens setup time during serial checks. With a resolution of 0.005 mm and a stated accuracy of ±0.005 mm, the device is suited to inspection tasks where sub‑millimetre conformity is critical, for example in precision bearings, small bores and gauge verification.

Compact range designed for micro and fine mechanical work

Classified in the micro range (10–100 mm), this short‑span model (16–20 mm) offers the stiffness and handling advantages required for watchmaking, instrument construction and small‑part assembly. The compact geometry minimises deflection and enables controlled contact pressure, so measurements remain stable even when taken by hand. The analogue operation provides tactile feedback preferred in many metrology benches and workshops where straightforward, robust instruments are required.

Practical advantages for workshop routines and inspection

Mechanically simple construction reduces maintenance and supports long service life under normal workshop conditions. The three‑point contact spreads the measuring force evenly, reducing local deformation of soft components and enabling reliable readings on cylindrical bores. The analogue scale with 0.005 mm graduations is immediately interpretable without batteries or electronics, making the instrument a practical choice for routine quality control and on‑bench verifications.

Integration into quality processes and tooling sets

The micrometer’s compact measuring range makes it an efficient addition to existing inspection kits and fixture checks. Its self‑centring action and fine graduation help standardise procedures: fewer adjustments are needed, inspection throughput increases and process capability feedback becomes more consistent. For environments seeking to improve first‑pass yields, this instrument provides a low‑complexity solution that complements digital and high‑precision gauges without duplicating functionality.
