Abstract
A profiling device for use with a machine tool includes a sleeve adapted to be attached to the machine tool and a tool carrier shaft rotatably mounted in the sleeve. The axis of the shaft is offset at a working angle relatively to the axis of the sleeve, so that the shaft carries out an oscillatory movement relatively to the sleeve when the shaft or the sleeve are rotated. The outer end of the shaft is adapted to receive a suitably shaped tool which can cut progressively into a workpiece until the entire profile has been produced when the relative rotational velocity of the workpiece and the tool is substantially zero.
Claims2
A profiling device, comprising a sleeve, a conical portion extending from one end of said sleeve for attaching it to a machine tool, a flange detachably connected to the other end of said sleeve, a hollow tool carrier shaft rotatably mounted in said sleeve and having a longitudinal axis extending at an acute angle to the longitudinal axis of said sleeve, said flange supporting said shaft, sliding thrust ball bearings supporting said tool carrier shaft within said sleeve, whereby the tool carrier shaft describes an oscillating movement relatively to the sleeve when it or the sleeve are relatively rotated, a portion of said shaft extending beyond said sleeve, a positioning rod extending transversely to said shaft and having an end screwed to said portion of the shaft, and a shaped tool screwed to the end of said portion of the shaft.
