Abstract
1498689 Abrasive wheels KENDIA (DIAMOND PRODUCTS) Ltd 31 Aug 1976 [11 Oct 1975 19 Dec 1975] 41735/75 and 52000/75 Heading B3D A cutting disc comprises a disc-shaped metal mesh core having a radially inner portion and an integral radially outer portion, a layer of abrasive particles adhered to the outer portion by a layer of electro-deposited metal, and a layer of resin over the mesh core and the abrasive particles. In one embodiment, a mesh disc 10, Fig. 1, of expandable metal or wire mesh is stamped with a centre hole 11 and a a radially inner portion defined by a line 12 is sealed by a protective layer such as an acidresistant paint, lacquer or plastics sealing washers. The outer portion of the disc is then cleaned and metal, such as nickel, and diamond particles electro-deposited thereon. Thereafter, the disc is placed in a mould and a resin based material 14, Fig. 2, such as phenol-formaldehyde novalak or resole, rubber, shellac, melamine or urea formaldehyde resin, epoxy resin, polyester, polyimide or polyamide, mixed with abrasive particles, for example silicon carbide or aluminium oxide, is moulded over the whole surface of the disc. In another embodiment, a mesh disc 10, Fig. 3, having a radially outer portion 20 integral with radially inner sectors 21 is formed by etching the mesh pattern on a steel plate, the diamond shaped openings in the outer portion being aligned in the radial direction of the disc. The surface of the plate between the etched lines is coated with a resistive material and the plate placed on a horizontal position in an electro-plating bath, diamond particles being spread around the radially outer portion 20, and electro-plating of metal, such as nickel, effected to build up a mesh on the plate which is then stripped from the plate and has diamond particles in its radially outer portion. A coating of resin based material is then applied to the disc as in the first embodiment. In either embodiment, the radially outer position may be formed with corrugations which become slightly flattened during application of the resin based material, Fig. 5.
