3 3. iamond and CBN tools iamond and CBN tools Interesting facts iamond and CBN S are available in galvanic, resin, metal or vacuum-brazed bonding Galvanic bonding With this type of bonding, the diamond or boron nitride grain is bonded to the carrier by galvanisation. he bonding is applied in layers, whose thickness is dependent on the. In special cases, however, several layers may be applied. In this bonding, the abrasive grits project to a relatively high degree from the bonding. hese tools are highly effective and allow high cutting rates. his bonding allows economical and rapid manufacture of special tools. Recoating of the worn tool is possible. Applications ungsten carbide and tungsten carbide green compact, glass-fibre reinforced plastics, fibre-reinforced, duroplastics and thermoplastics, electrocarbon, ferrite, graphite, glass, rubber (diamond), high-speed steel, hardened steel, high alloy steels (boron nitride). Cutting speed: Approximately m/s and diamond or boron nitride grit. Grinding tools with metal bonding are manufactured by sintering. he high degree of hardness of the metal bonding renders the grinding wheel very resistant to wear, but is not as effective as the other bonding systems. Concentration C100 as standard Applications Ceramic materials, glass, profile grinding of tungsten carbide, ferrite (diamond). Cutting speed: Approximately m/s Vacuum-brazed bonding With this bonding type, the abrasive grits are directly fused with the carrier. he adhesion of the grits can thus be greatly improved. he grain protrusion results in a very high removal rate. Applications hese tools are particularly suited for glass fibre-reinforced materials and carbon-fibre reinforced plastic (in aircraft construction and shipbuilding), tungsten carbide green compact (unsintered tungsten carbide), ceramics (i.e. valve covers for car engines), coal products (i.e. brake discs, car- bon brushes) and cast materials. Cutting speed: Approximately m/s iamond and boron nitride abrasives iamond and boron nitride are the hardest abrasives in the world. hey are far harder in comparison to conventional abrasives such as corundum and silicon carbide. iamonds exist in natural and synthetic form. Boron nitride exists only in synthetic form. iamonds are made of carbon and are excellent for grinding short-chipping materials. Owing to the fact that the carbon in diamond is incompatible with the carbon contained in steel, diamonds are unsuitable for steel processing. iamond consists of carbon and is perfectly suited for grinding short-chipping materials. Because of an incompatibility of diamond carbon with the carbon in steel, diamond cannot be used for steel machining. Boron nitride contains no carbon and is optimally suitable for grinding different types of steel. he high level of hardness of diamond and boron nitride presents a number of advantages, such as a long service life, precise reproduction of shape and exact dimensions during the machining process. Resin bonding In resin bonding, the diamond or boron nitride grain is densely compressed over the entire coating. Synthetic materials with different properties are used as binders. he quantity of grains distributed over the abrasive coating is dependent on the concentration. his bonding is characterised by a low grinding temperature and high stock removal. It has established itself for tool grinding applications. It allows a high surface quality to be obtained. i s FEPA standard U. S.

36 . iamond and CBN tools // 3.5. iamond sheets and strips 3 iamond and CBN Special tools For service beyond the call of duty. You have an aim, but not yet a solution. We can develop the complete tool on your behalf - from the design/drafting stage, including manufacture of the blank, to coating. You already know your requirements, but are still not aware of the best possible, most economical solution. Selection of the grit : It is advisable to select the grit as coarse as the desired surface quality allows. We recoend 126 as a medium grit for general grinding of metals and hard materials. s >356 should preferably not be used. Coarser diamond grits in the range of 181 to 602 can be used in plastic and rubber finishing. Fine and extremely fine grits can be used for special applications. thickness For a tolerated dimension in the coated area, account must be taken of the coating thickness when manufacturing the blank. Please contact our Product Manager Stefan Spiegel on all issues regarding (special) diamond tools: el. +49 (0) / s.spiegel@joke.de You provide us with your drawing (or even just a sketch) and we will deal with the rest, right down to the ready-to-use tool. You already have a blank of the tool, or even a worn tool. We will rework the tool on your behalf and apply the necessary coating. Notes on manufacture of the carriers (blanks) Material: Blanks should preferably be made of low alloyed or unalloyed chromium-free steels, e.g. C 60, C 45, S 37, which guarantees optimum bonding between the galvanic layer and blank. Prerequisite: fine turning, milling or grinding are adequate machining operations for surfaces to be coated. It is important that all rotating tools are manufactured with optimum radial run-out, since generally, the tools can no longer be dressed after coating. Recoating of worn tools ools with galvanic bonding, like any other tools, are subject to natural wear and tear. Since the iobilisation time of a tool considerably affects the productivity of the working process and the price of the product to be manufactured, extending tool service life is a decisive factor. his is why our tools can be recoated several times. his is of value primarily when on the one hand, the proportion of expenditure for design and/or manufacture of the carrier has incurred a considerable percentage of the costs or when appropriately high numbers of the same tools exist. he prerequisite in this case is merely that the carrier remains free of defects in terms of true running and geometrical shape. ressing of a damaged carrier after the coating is lost is worthwhile only in exceptional cases, since in most cases, the requisite expenditure for repairs approximates that of a newly manufactured product. el. +49 (0) / Fax +49 (0) / info@joke.de 287

Optimally usable in case hardening and tenacious unhardened steels, for example during elimination of hardness distortion or bur formation on cutting, moulding and punching tools. iamondcoated files are also used for processing of carbide metal, ceramic, glass fibre-reinforced plastics, carbon fibre-reinforced plastics, carbide metal green products, ferrites and many more. Owing to the diamond grits projecting from the bond, optimum results can already be obtained with light contact pressure. s of 30 (very fine) to 252 (very coarse) are available.
