Abstract

PURPOSE: To achieve polishment with high accuracy, by forming an original disc through the processing of a shartp angle ridge of straight line, circular arc or spiral shape on the surface by the combination of bytes with obtuse angles, and forming a polishing disc with a shartp angle profile groove through replica- inversion.
CONSTITUTION: A diamond cut blade 6 has a right side blade and the profile is formed as a transversal blade angle θ over a distance equal to the height of a triangle ridge with a minute front clearance, transversal clearance θ4, rake and side rake θ6. A diamond cut blade 7 has a left side blade and also has a front clearance, transversal clearance θ3, rake and side rake θ5 almost equal to the blade 7. The blades 6, 7 are opposed with each other and fixed to a shunk via a liner 4 with screws 5. An original disc 2 is shaped by using the bites like those, a nickel film 8 is attached and a substrate 10 is stuck by using an adhesive 9, and then the film 8 is peeled off from the original disc 1 to form a polished disc with triangle grooves with a sharp thread bottom angle. Video reproducing styluses are polished by using the polishing disc like this to form stylus tips with high accuracy.
