摘要： PROBLEM TO BE SOLVED: To provide a high-efficient and stable optical precision lens at a low cost. SOLUTION: One surface of a lens material 5 having size large enough to allow production of lenses with a plurality of optical lenses arranged is integrally machined in a spherical state to form an outside spherical surface part. The lens material 5 is held by a holding device, and a grinding wheel 31 is rotated centering around a grinding wheel rotary axis T. By a so formed grinding device, grinding is executed through advance and withdrawal as rotation is effected to orderly manufacture a plurality of lens material individual pieces 40 with the device arranged such that the extension line of the grinding wheel rotary shaft T passes the core 2a of the outside spherical part. Thereafter, the reflection surface of the lens material individual piece 40 is machined to produce a desired optical lens.

摘要： PROBLEM TO BE SOLVED: To manufacture a small-diameter and small-curvature lens and a lens forming metal mold surface with high accuracy and at a high grade by controlling a flow of slurry jetted from a pore provided in the tip of a polishing tool to a fixed flow and moving the polishing tool near by the surface of an object to be polished at a fixed stay time. SOLUTION: At the time of jetting slurry 4 obtained by previously mxing water 8 and fine abrasive grains 7 at a fixed ratio forcibly from a pore 3 to be strongly applied to the surface 5 to be polished, the fine abrasive grains 7 cause the polishing action to the surface of the surface 5 to be polished. An object 1 to be polished and a polishing tool are controlled to be relatively rotated or reciprocated so that the stay time of the polishing tool is controlled to make a pore 3 stay uniformly to the surface 5 to be polished. The liquid feed pressure and the flow of the slurry 4 are controlled so that the polishing tool is a little floated from the surface 5 to be polished to attain satisfactory polishing action of the fine abrasin grains 7. At this time, it is necessary to prevent such a movement locus control that a specified part of the pore 3 polihses a specified part of the surface 5 to be polished.

摘要： PROBLEM TO BE SOLVED: To provide a producing method for magnetic head which easily realizes track control of high precision by processing the track control at a time in the stage of a core bar and not generating errors which have been a problem in a conventional method and are accumulated in every process. SOLUTION: A prescribed groove is formed on a prescribed surface of one of two core half bodies, and the surface of the core half body where the groove 23 is formed and a corresponding surface of the other core half body are polished into a prescribed surface roughness, and a prescribed nonmagnetic thin film is stuck to polished surfaces, and surfaces to which the nonmagnetic thin film is stuck of the pair of core half bodies are brought into contact with each other, and in this contact state, they are subjected to heat treatment at a prescribed temperature and are press-fixed to form a core bar 21. A line 26 on the surface of the core bar 21 is used to form plural holes 27 at such intervals practically on the line 26 from the surface of the core bar 21 toward the opposite surface by electro-discharge machining that a prescribed track width is left. Further, plural holes 27 of the core bar 21 are packed with molten glass, and the core bar 21 is cut by a prescribed size including the prescribed track width, thus producing the magnetic heads.

摘要： PURPOSE:To provide the method for polishing the forming surfaces, such as axisymmetrical, nonaxisymmetrical and free curves of the metal mold for forming optical parts with high accuracy. CONSTITUTION:The forming surfaces are polished by interposing a polishing material 16 into the spacing between the metal mold 11 subjected to shape working and a tool 13 having the surface shape matching the forming surfaces of the metal mold 11 and applying ultrasonic vibrations by an ultrasonic horn 15 to the tool 13. As a result, the surfaces are specular polished in a short time without deteriorating the accuracy of the forming surfaces of the metal mold subjected to shape working.
