This paper describes a synchronous controller for high-productivity NC gear grinding machines that use a screw-shaped CBN wheel of multithread. The authors developed a high-precision controller for productive-type NC gear grinding machines in 1995. Because it was based on analog circuits, it required very complex electrical circuits. In this paper, we propose a PC-based synchronous controller to decrease production costs and add useful functions to it. The most useful one added this time is a function to increase pitch accuracy of gear ground with the multithread CBN wheel. Next useful one is a function to attain high-accuracy initial meshing between gear and CBN wheel. Because grinding-spindle and work spindle rotate at a high-speed, two-phase type PLL is applied to the controller. Grinding experiments showed that the newly developed controller has excellent performance.
