Establishing the quality control most suitable for the precision demanded

The stator shaft is an important component of the CVT. Production of this component requires a high level of precision with tight tolerances in terms of roundness, cylindricity, and straightness. Load waveform data, generated during the process in which plugs are pressed into flanges, is stored via computer in order to achieve traceability for each and every unit produced.

Rotor shaft

For very low-tolerance processes, total 100% measurement and feedback are conducted to maintain a high level of process-assurance capability.

Stator shaft Assy

Load waveform data, generated during the process in which plugs are pressed into flanges, is stored via computer in order to achieve traceability for each and every unit produced.

Hydraulic equipment performance test bench

All assembled products are subject to a quality assurance system involving automatic shipping testing that checks hundreds of aspects of the items.
