Metrological Efficiency and Construction Solidity borletti
The MELN-3W (BORMELN-3W) is a classic micrometer that combines high-quality materials with superior handling. Its design is designed for intensive use in service laboratories and production departments, where measurement stability is essential to ensure the conformity of machined parts.
Technical and Mechanical Features
- Thermally Insulated Structure: The forged and minted alloy steel bow is painted and equipped with special insulating plates that protect the instrument from the heat of the operator's hands, preventing unwanted thermal expansion.
- Precision Mechanics: The micrometric screw is subjected to hardening and stabilization processes to ensure smooth movement and extremely high wear resistance over time.
- Superior Contact Surfaces: The contacts are made of hard metal , ground and lapped with a high degree of flatness and parallelism (surface roughness Ra = 0.03 µm ).
- Force Regulation: The graduated drum (Ø 17 mm) integrates a friction ring , essential for applying a constant and repeatable measuring force on each piece.
- Locking System: Features an easy-to-use locking lever to secure the vernier position after taking the measurement.
Areas of Application
Essential for dimensional inspection of mechanical components, shafts, and thicknesses in the 50-75 mm range. Full compliance with international DIN, UNI, and ISO standards makes it a suitable tool for inclusion in certified quality management systems.
