Gear Measuring Centre Model 3915,3920

Model 3915 and 3920 gear measuring centres can accomplish a variety of gear measuring tasks including the inspections of tooth data on cylindrical gears (external spur and helical gears) and herringbone gear (standard module). These gear measuring centres series particularly suit heavy-duty industrial applications of ship building, mining and metallurgy.


  • Compact construction of basic machine, high measuring accuracy and reliability. The basic units of these gear measuring centres are provided with five-axis measuring systems. With the help of rigid multi- row rolling guides, ball screw, Germany-made linear and angular encoders, imported motor and TESA lever type probe, high measuring reliability is guaranteed.
  • Complete measurement of tooth data and wide range of application. The functions of the measuring software include evaluations of tooth profile deviations (Fα,ffα,fHα ) helix deviations(Fβ,fβf ,fHβ ), pitch deviations (Fp,Fpk,fpt) and runout ( Fr ).
  • Fully automatic measuring cycle with fast measuring speed. This measuring centre permits automatic checking of all test items such as profile, helix and pitch deviations and runout in one set-up. The measuring cycle is automatically controlled by microcomputer.
  • Powerful measuring software functions with simple operation The measuring item can be selected according to the workpiece to be tested. This user friendly measuring software provides automatic evaluation of cylindrical gears in accordance with ISO1328. The special functions in the measuring software include evaluations of K chart, profile barreling Cα , and tooth crowning Cβ.
