Development of Spindle-finish Type Finishing Apparatus and Its Finishing Performance using a Magnetic Abrasive Machining Process

Abstract

This paper describes a new spindle-finish type finishing apparatus and the finishing performance it provides when using magnetic abrasives of 0.15 mm in diameter in a magnetic field. The features of this maching process are : the finishing process is carried out with the application of magnetic force instead of the centrifugal force of finishing media in the conventional barrel-finishing process ; the finishing force of the magnetic abrasives is controlled by exciting current of a magnetic coil ; and surface finishing, deburring, and precision rounding-off of the workpiece are done simultaneously.
