Abstract
A rotary machine tool, such as a grinding wheel, is mounted on a movable support serving to advance the tool toward a workpiece, such as a pipe to be severed thereby. The tool is driven by an electric motor whose operating current is measured by a sensor controlling the fluid supply to a hydraulic servomotor which is linked with the support. When the advance is too rapid, the resulting rise in load resistance increases the operating current and causes a throttling of the fluid pressure, the rate of advance being thus optimized in conformity with the shape and/or composition of the workpiece.
