Abstract
The grinding toolholders of a grinding machine for the fine grinding or honing of a camshaft or other workpiece are displaced along nonrotatable threaded spindles by high-precision rotatable nuts which are driven by a stepping motor on each holder via a cog belt coupling all of the nuts of each holder with the stepping motor. This ensures synchronous drive of the nuts and allows narrow holders to be used to grind closely spaced zones without the danger of canting of the holders.
