Industrial Precision and Metrological Quality borletti

The MELN-4W (BORMELN-4W) combines the superior features of borletti's metrological tradition with superior handling, essential for intensive workshop use. Its structure is designed to ensure consistent results in the dimensional control of medium- and large-sized components, ensuring maximum metrological stability.

Technical and Construction Features

  • Advanced Thermal Protection: The bow is made of forged and minted alloy steel , painted, and equipped with special insulating plates. This system protects the instrument from the heat of the operator's hands, preventing thermal expansion that could affect the accuracy of the survey.
  • High Precision Mechanics: The micrometric screw is hardened and stabilized , ensuring smooth movement and superior wear resistance over time.
  • Hard Metal Contacts: The contact surfaces are ground and lapped with a high degree of flatness and parallelism, boasting an extremely low surface roughness ( Ra = 0.03 µm ).
  • Force Control: The 17mm diameter graduated drum is equipped with a friction ring , allowing a constant and repeatable measuring force to be applied to each piece being inspected.
  • Safety System: Includes an easy-to-use lever locking device to secure the vernier position after measurement.

Areas of Application

An indispensable tool for precision mechanical workshops, repair shops, and testing laboratories working on shafts, shims, and mechanical components in the 75-100 mm range. Compliance with DIN, UNI, and ISO standards makes it suitable for inclusion in rigorous quality management processes.
