Paper Abstract

Laser Micro-Bending technology attracts attention as one of the laser processing technology promising from now on. It has the feature that does not contact and does not have the spring back that fabrication in high accuracy can be performed. In our company, Laser Micro-Bending technology development is tackled about ten years before, and the laser bending fabrication technology of a sheet metal and ceramic material has so far been established. It has utilized as rapid prototyping of the sheet metal. But, by re-examination of laser oscillation control etc., it finds out that it is the excellent processing method for manufacture of the high precision mechanism parts for magnetic disk drives. This report explains the technology and machines of the roll and pitch adjustment of a magnetic head suspension, and flatting or crowning of the air bearing surface of a magnetic head slider by using Laser Micro-Bending technology.
