<p>PURPOSE:To stably obtain parallel surfaces with a high degree of accuracy in polishing of both surfaces of a magnetic head, by fixing a workpiece to a first holder for polishing a first surface of a workpiece and by fixing a second holder to thus polished surface of the workpiece for polishing a second surface of the workpiece. CONSTITUTION:A workpiece 3 is bonded to a first holder 1 having a flat surface with a high degree of accuracy by means of an thermofused adhesive agent 4 to polish a first surface 3a of the workpiece 3 so as to have predetermined flatness and surface roughness. Then, the first surface 3a is made into close contact with a second holder 2 and the workpiece 3 is secured thereto by means of a non-heatable adhesive agent 5. Thereafter, the first holder 4 is heater up to the fusing point of the adhesive agent 4 to be removed from the workpiece 3 which is therefore shifted onto the second holder 2 in order to polish the second surface 3b so as to have an optional thickness, and desired flatness and equivalent surface roughness. Thus, it is possible to enhance the working efficiency and to obtain parallel flat surfaces with a high degree of accuracy.</p> |
