The NPFLEX-LA combines the intrinsic benefits of Bruker’s gauge-capable, interferometry based 3D optical profiling technology with new patent-pending metrology capabilities to quantifiably measure both shaft lead angle and surface texture of sealing surfaces in a single, integrated solution. Designed to perform extremely accurate metrology independent of part warp, level, concentricity or mounting inconsistencies, the NPFLEX-LA also features a streamlined production user interface that enables rapid setup and easily set pass/fail criteria to identify and/or discard nicks, burrs, and scratches from a measured surface area on a machined shaft.
“The average automobile has numerous dynamic seals that can fail,” explained Stanley Smith, consultant and industry expert in sealing surfaces. “Failures attributed to leaking seals cost the transportation and power equipment industry tens of millions of dollars a year in warranty costs, recalls and fines. Given my 50 years of experience in the oil seal industry, it is very exciting to see that Bruker has come up with an innovative, noncontact measurement for shaft lead angle. The NPFLEX-LA will allow the sealing industry to continue to drive roadmap development beyond existing designs and achieve warranty targets at a reduced cost.”
The Bruker NPFLEX and NPFLEX-LA optical metrology instruments utilize a gantry design to provide over 300 degrees of access for large samples. A swivelling optical head option permits routine investigation of highly curved samples and bevelled edges. The NPFLEX-LA utilizes an easy-to-use, three-jaw chuck design to allow for the mounting of shafts for lead angle and surface texture measurements. Both
