Reishauer RZ550 Gear Grinding Machine

Reishauer RZ550 HAMADA KOKI CO. LTD installed Reishauer RZ550 gear grinding machine in January 2016.

Until then, we experienced noise problem when continuous grinding with the screw-shaped grinding wheel due to irregularities that formed on the gear tooth surface.
RZ550’s NC software has a low-noise grinding shift function that make it possible to reduce noise as it grinds along tooth trace direction while correcting unevenness on tooth surface.

In addition, after performing bias correction through twist control of helical gear and regular grinding, gear tooth surface roughness can be improved by polishing with elastic grinding wheel.

We’ve begun new challenges by utilizing these latest technologies.
