Taper Turning

Taper turning is an operation to produce a conical surface on the workpiece.

This can be machined by either workpiece inclined to the axis of the lathe or a tool moving inclined to the axis of the lathe.

Taper Turning by Swiveling the compound Tool Rest

Taper Turning by Swiveling the compound Tool Rest
  • The workpieces which require a steep taper for short lengths the taper turning was done by swiveling the compound rest method.
  • In this method, the compound tool rest is swiveled to the required taper angle and then locked in the angular position.
  • For taper turning the compound, rest is moved linearly at an angle so that the cutting tool produces the tapered surface on the work piece.
  • This method is limited to short taper lengths due to the limited movement of the compound tool rest.
