Smartfit from Gleason is a fast, easy and economical way to optimize your existing Gleason SIGMA, GMM and GMS series machines, increase their productivity and the potential for profits. Now your SIGMA, GMM or GMS series machines can be upgraded for a wide range of surface roughness measurements, meeting the most common roughness parameters as defined in DIN, ISO and ANSI, including Ra, Rq, Rz, Rmax and more. They can now be upgraded to apply advanced Barkhausen noise analysis technology for the inspection of cylindrical gears and other rotationally symmetrical workpiece for surface hardness, residual and compressive stresses-particularly important after carburizing/induction hardening and grinding.
