Abstract: A profile plano-type knurling machine relates to metal pressure shaping machinery. It is more expedient to use the present invention for working splined shafts, polygonal parts and gears. In the present knurling machine a device for moving knurl rollers in the radial direction relative to the centers has tapered elements kinematically associated with the knurl rollers and pressure members whereas only one pressure member intended to provide the radial feed of the knurl rollers is installed on the fixed support member at the side of the bases of the tapered elements coaxially to the centers and adapted for actuating simultaneously all the tapered elements through an intermediate part located between said pressure member and the bases of the tapered elements. This technical solution provides for a considerable improvement of the machine efficiency and its reliability in operation as well as processing accuracy of the work pieces being machined.
