<p>PURPOSE:To provide high accuracy in finished configuration by heating the surface of a workpiece while gradually cooling and bonding the workpiece and thereafter polishing when the workpiece consisting of a plurality of materials having different coefficients linear expansion is bonded to an attached surface plate through thermoplastic adhesives. CONSTITUTION:Thermoplastic adhesives 3 like electrowax are thinly uniformly applied on an attached surface plate 2 and a workpiece 1 formed of a plurality of materials having different coefficients of linear expansion is mounted on said adhesives pressed and stretched by hands to provide uniform adhesion. Then, the surface of workpiece 1 is heated by an infrared ray heater 4 while being gradually cooled and bonded. Then, the warping of workpiece 1 caused by a difference between room temperature and bonding temperature is corrected by the infrared ray so that the workpiece 1 is bonded to the attached surface plate 2 while keeping the configuration under the room temperature. Thus, high accuracy adhesion can be provided and high accuracy configuration can be polished.</p> |
