Abstract
456,950. Grinding-wheels ; moulding. NORTON GRINDING WHEEL CO., Ltd., Welwyn Garden City. Feb. 14, 1936, No. 4484. Convention date, Feb. 14, 1935. [Class 60] [See also Group V] An abrasive wheel comprises a non-abrasive central body of fibrous sheet-material associated with a resinoid forming a support for an annular rim formed of resinoid-bonded abrasive grains which is integrally secured to it. The invention is applicable to the manufacture of very thin cutting-off wheels in which the abrasive consists of diamond dust, but other abrasives such as silicon carbide, crystalline alumina or boron carbide, united by a resinoid bond, may be employed. The central support may consist of a number of thin sheets 24 of fibrous material, such as paper or cloth impregnated with synthetic resin, which in manufacturing the wheel are assembled in a mould around a central arbor 22. The annular space between the sheets and the wall 10 of the mould is filled with the mixture 28 of abrasive and resin bond and the mould is compressed between the platens 16, 18 of a hot press, the resinoid in the central and abrasive portions of the wheel being converted to the infusible state and integrally uniting the whole. To strengthen the wheel, a perforated metal disc may be interposed at the centre of the fibrous sheets 25. Thicker sheets, or a single thick sheet, of resinoidimpregnated fibrous material may be substituted for the thin sheets 24. A cup wheel may be formed by securing the abrasive annulus to the end face of the central support. U.S.A. Specification 1,981,970 is referred to.
