A New Method of Reducing Shock between Press Head and Press Disk in High Speed Lapping


Article Preview

Considering the shock between the press head and press disk in high speed lapping is more serious, this paper proposes a new method to reduce this shock. By this method a hole is machined for air passing on the press head axis. The topper of the hole is connecting with a pressure air resource. Thus an air cushion between the press head bottom and press disk on the workpiece is produced. With the distance between them reducing gradually, the damping of air cushion on the press head increases gradually. This makes speed of the press head approaching the workpiece decrease gradually and until reach zero. The pressure of the press head acts on the press disk increases gradually from zero to working pressure, which can reduce the shock between the press head and workpiece effectively, prevent weak workpiece from destroying in lapping and improve machining accuracy and quality. This method possess the advantages of easy to carry out, simple to operate and convenient to apply.
