Taper Cutting in Lathe

TAPER CUTTING IN LATHE MACHINE


A taper is defined as a uniform increase or decrease in diameter of a piece of work measured along its length. In a lathe machine, taper turning means to produce a conical surface by gradual reduction in diameter from a cylindrical job. 

Swiveling compound rest set-up
A taper is generally turned in a lathe by feeding the tool at an angle to the axis of rotation of the work piece. The angle formed by the path of the tool with the axis of the work piece should correspond to the half taper angle. A taper can be turned by anyone of the following methods:

1. By Swivelling the Compound Rest.
2. By Setting Over the Tailstock Centre.
3. By a Broad Nose form Tool.
4. By a Taper Turning Attachment.
