    摘要: A substrate polishing method includes starting to rotate a circular substrate and polishing an inner peripheral edge surface of a center circular hole formed in the circular substrate into a chamfered or rounded surface by pressing the inner peripheral edge surface against a bypass polishing part of a polishing tape that is conveyed intermittently or continuously and by oscillating the bypass polishing part of the polishing tape about a direction perpendicular to a direction that the center circular hole penetrates through the circular substrate. The polishing tape is guided so as to have an advancing portion advancing toward the circular substrate, a returning portion returning from the circular substrate, and a turning-back portion between the advancing portion and the returning portion guided along a side bypass. The bypass polishing part of the polishing tape is the turning-back portion of the polishing tape.

    摘要: A hard crystal substrate such as a GaN substrate or a SiC substrate is polished by using polishing oil slurry having abrading particles of artificial diamond clusters dispersed in a dispersant. The artificial diamond clusters include approximately spherical agglomerate particles with average particle size D50 of 20 nm or more and 50 nm or less, having primary particles with particle diameters of 2 nm or more and 10 nm or less. A rough polishing process is carried out first such that an average surface roughness of 0.5 nm or more and 1 nm or less is obtained, followed by a finishing process such that the average surface roughness of said surface becomes 0.2 nm or less.

    摘要: A polishing sheet suitable for precise polishing is produced by arranging polishing particles as a single particle layer on a base sheet and includes a base sheet and a polishing layer made of polishing particles and a binder resin for fixing the polishing particles that are arranged as a single particle layer. The polishing particles protrude partially from the surface of the binder resin, being covered or not covered with a thin film of the binder resin.

    摘要: A method of texturing a surface of a magnetic hard disk substrate includes the steps of rotating the magnetic hard disk substrate, supplying polishing slurry on the surface of the substrate, and pressing a polishing tape on the substrate surface and running the polishing tape. The polishing slurry includes abrading particles of monocrystalline diamond that are cluster particles with corners having diameters in the range of 1-10 nm, dispersed in a dispersant such as water and a water-based aqueous solution. The cluster particles are tasseled assemblies of crystalline particles with no directionality.

    摘要: A disk processing device holds and rotates a disk with a spindle. Processing tapes are supplied out and wound up by a tape reel unit so as to sandwich and be pressed on both surfaces of the disk through contact rollers. As a crankshaft is rotated, a sliding plate rotates around it and a slidable shaft rotates around a fulcrum part while sliding along the sliding plate such that the contact roller undergoes a reciprocating motion in a radial direction of the disk together with a slider rotatably attached to the slidable shaft.

    摘要: A polishing system and a method are presented for uniformly polishing efficiently at a fast rate the surface of a tape-like metallic base material of several hundred meters in length. The polishing system is provided not only with devices for causing the base material to travel continuously and applying a specified tension in the base material but also with a first polishing device for randomly polishing the target surface and a second polishing device for carrying out a final polishing on the target surface in the direction of travel of the base material. Polishing marks are formed in the direction of travel on the target surface by the final polishing.
