The desire for support and service has always been part of the DNA of J. LANFRANCO & Cie.
The company has recently acquired new inspection machines that further enhance its ability to ensure the highest standards of quality in its products.
J. LANFRANCO is the only French nut manufacturer to be able to offer the validation of its parts in its manufacturing process. We now have even more efficient means of investigation. With this latest equipment, our company reaches the same level of expertise as private laboratories.
Our safety fasteners are designed to meet the highest standards in the railway sector.
These investments make our company one of the French flagship manufacturers of self-locking safety systems in compliance with standards NF EN ISO 898-2, NF EN ISO 3506-2, NF EN ISO 2320, NF E25-035-2.
The AUTOMATICA, our new measuring bench can perform torque/tension tests from M5 to M39 according to quality classes. We have a new four-way sensor to measure the under-head and in-thread coefficient for dimensions ranging from M16 to M39. We also carry out tests on imperial dimensions. With the level of precision of this bench, we can accurately measure the performance of the surface treatments and/or Filmogène (top coat) offered by our company. This acquisition ensures that our customers comply with the friction coefficients specified in the order.
We recall the importance of controlling the coefficient of friction, because it is directly related to the torque and tension in the assembly.
The ZEISS binocular machine by its magnification capacity (x1000) and the integration of measuring software, allow us to directly control the protection thicknesses on our products.
This enables us to ensure that our products comply with the strictest constraints.
