Honing apparatus for producing a precision surface on a workpiece

Abstract

A honing apparatus for producing a precision surface on a workpiece is disclosed. The honing apparatus includes a shank having a first zone positioned at substantially proximity to a distal end of the shank and a second zone positioned at substantially centre of said shank. The first zone has a rough grit diamond than the second zone. The honing apparatus includes a centering section positioned at the distal end of the shank. The shank connects to a honing machine via an adapter. The shank axially advances towards an area on a workpiece to be precision finished, while rotating and reciprocating relative to the workpiece to be precision surfaced. The centering section centers and aligns the shank at the workpiece such that the workpiece comes in contact with the first zone followed by the second zone. The first zone and the second zone remove a stock of material from the workpiece for precision surface on the workpiece.
