GEAR TESTING The Leitz PMM-F and PMM-G machines are also available with short Z-axes for the use as dedicated gear testing machines. Together with QUINDOS, all types of gears (cylinder gears, spiral bevel gears, clutch gears, gear racks, curvic couplings and many more) can be measured. Even all types of cutting tools, such as hobs, form cutters, shaper cutters, shaving gears and broaches, can be measured precisely, reliable and economically. Pallet measurement of gears is also possible as there is no rotary table required for the inspection of gears or gear cutters. Time consuming alignments of heavy gears are no longer required, resulting in an unmatched measuring throughput. Another advantage in comparison to conventional gear testers is the possible gear diameter range. Here, the Leitz PMM-F is capable of measuring gear diameters from 10 to 1,950 mm. With the Leitz PMM-G, gears with diameters from 10 to 4,450 mm can be measured. 8 LEITZ PMM-F / PMM-G | XXL-Class CMMs and Gear Inspection Centers
