The GTR series, double-flank gear rolling tester that can measure the composite gear accuracy in a short time.
High-precision measurements are made from plastic-molded gears to large gears, and they can be classified according to major gear standards. Using the composite test technology of GTR series, automatic gear selecting machine for in-line process is also supported.
