Abstract

This paper proposes a new centerless grinding technique using surface grinder. It is a technique that centerless grinding operations are performed in low cost by installing a compact centerless grinding unit consisting mainly of an ultrasonic elliptic-vibration shoe, a blade, and their respective holders on the worktable of a multipurpose surface grinder without the employment of a costly centerless grinder. The function of the shoe is to hold the cylindrical workpiece together with the blade, and to control the workpiece rotational speed with the elliptic motion on its end face during grinding. In this report, the design and manufacture of a centerless grinding unit, and several grinding operations on the produced unit using a surface grinder are described.
