Stampinox S.r.l., a leading company in the hot-forged special fasteners sector, is located in Merone, Italy, halfway between Como and Lecco. It manufactures fasteners with no dimension limits and with diameters as small as M6 (metric system) or ¼” (imperial system), in alloy and stainless steels, titanium, duplex, super duplex and special alloys and materials.
Highly qualified personnel carry out control activities using inspection and testing systems and up-to-date procedures. The use of control instruments capable of preventing the waste of materials and time is also fundamental. “In recent years,” Stefano Marelli explains, “many of our clients have started requesting fasteners with increasingly strict tolerances to be used on parts with shapes and dimensions that are very difficult to measure. With traditional measurement instruments, it was extremely laborious to check measurements and concentricity, planarity and linearity rations on elements that are so small and, at times, also difficult to reach. We also tried out other types of solutions, such as mechanical sensors and probes, but we were never completely satisfied”.
Stampinox therefore decided to acquire a more technologically advanced instrument, the FARO Edge portable coordinate measurement machine (CMM). Stefano Marelli explained: “We have found the FARO Edge to be the ideal instrument to meet our needs. It is capable of easily checking product quality using 3D inspections and measurements, dimensional analysis and CAD comparisons. It is also much more flexible than other 3D measurement devices: it can be used in the metrology room as well as on-machine right in the workshop. This last feature is particularly useful and convenient, since it enables us to speed up in-process as well as end-of-process controls. That saves us precious time.”
The FARO Edge measurement arm uses next-generation technology to guarantee top-of-the-line performance and reliability. Users will also find the device even simpler to use due to its integrated computer touchscreen. Stefano Marelli continued: “It was quite straightforward to begin using the measurement arm at our company. The FARO technicians who worked alongside us during the initial period of training and support helped us to appreciate how easy it is to use. It is no coincidence that the FARO Edge is used not only by measurement personnel, but also by other non-specialist staff.”
Today, about one year since it was purchased, the FARO Edge has become an indispensable tool in the Stampinox workshop. Stefano Marelli stated: “When it comes to verifying tolerances in particular, this instrument provides extremely high levels of repeatability and accuracy, fully in line with the objectives we had set for ourselves. However, it is especially the measurement acquisition speed that has left us absolutely satisfied: with the FARO device, the speed of control operations has increased considerably, typically by around 20-30%.” To sum up, as confirmed by Stefano Marelli, this device has turned out to be an important and crucial investment for Stampinox: “The FARO Edge has allowed us to take a significant step forward, as it enables us to sell complex products that we previously had the technical capability of manufacturing, but were not able to measure adequately.”
