T

he modern abrasive industry is concerned with the manufacture and processing of abrasive materials for grinding, cutting, and polishing. The major materials used are aluminum oxide ( 7 ) , silicon carbide (3) and diamond (4). A l l of these are now made artificially, although natural diamonds are still an important factor. These items along with some naturally occurring abrasives are used i n grinding wheels, as coated abrasives, or i n loose form for tumbling or lapping. Metal-clad or coated diamonds have recently improved diamond wheels to a marked degree. Wheels made from metal-clad diamonds have been particularly effective i n grinding carbide tools w i t h steel shanks. There have been also remarkable improvements in the hub materials for diamond wheels, such as fiber-filled Bakelite resin, and i n diamond form tools, the single-layer diamond form wheel, and diamond abrasive belts.

History The first metal objects made by man were sharpened and polished with sand or other natural abrasives, either loose or i n the form of stones. Indeed, it is probable that some of the stone implements were also polished or shaped w i t h sand or with other stone materials. Pliny records the use of emery i n the first century A . D . D o w n through the centuries sand and sandstone have been used for polishing and sharpening, culminating in the use of the familiar grindstone for sharpening axes and other cutting tools. 112 In Literature of Chemical Technology; Smith, Julian F.; Advances in Chemistry; American Chemical Society: Washington, DC, 1968.

The modern history of abrasives begins with attempts to bond natural emery w i t h glue to other materials so that it might be applied to rotating machinery. About 100 years ago some silicate or water-glass bonded wheels were made. These were soon followed by wheels made w i t h vitrified or clay bonds. Other bonding materials w h i c h gradually came into use were cement, rubber, shellac, sodium silicate, magnesium oxychloride, and phenolic resins. The development of artificial abrasives, such as silicon carbide and fused aluminum oxide, greatly improved quality and reproducibility ( 3 , 2 0 ) . Sandpaper, initially made w i t h glue, and emery cloth, also bonded w i t h glue, have been augmented more recently for coated abrasives w i t h other bonds based on plastics and with a wide variety of backings and fillers. F l i n t , garnet, silicon carbide, and aluminum oxide have been the usual abrasives i n this service and have recently been joined by diamond. General

Literature

Abstracts concerning abrasives may be found i n Chemical Abstracts, Ceramic Abstracts, and the Industrial Diamond Review. In Ceramic Abstracts these are concentrated mainly i n the abrasive section, but i n Chemical Abstracts the references may w e l l be scattered throughout many sections. The Grinding W h e e l Institute and the Abrasive Grain Association are responsible for much of the general literature i n this field and may be considered to represent the whole industry on the N o r t h American continent. A historical record is provided by " T h e Saga of the Abrasives Industry." This volume was prepared by M u r i e l F . Collie and published by the Grinding W h e e l Institute i n 1951. Similarly, information on coated abrasives is available i n "Coated Abrasives, M o d e r n T o o l of Industry." D a t a on the abrasive uses of diamonds are offered by Engelhard Hanovia, Inc. and by the D i a m o n d Research Laboratory i n Johannesburg. Information on specific topics and various types of grinding is provided i n the trade literature of the various abrasive companies; a list of these companies is included i n the bibliography. Books. There is no general treatise covering the field of abrasives. The best summaries are provided on an annual basis by the Minerals Yearbooks of the U n i t e d States and Canada, respectively. Both of these contain information on the industry which lags about two years behind the date. There are good individual books on grinding wheels (such as L e w i s ' b o o k ) , on coated abrasives, on diamonds, and on bauxite, w h i c h is included here since it is the raw material for producing aluminous abrasives. Periodicals and Journals. The major journal i n this field is Grinding and Finishing. It has been i n publication since 1954 and contains a number of important articles i n the field. Industrial Diamond Review is devoted to articles on the use of diamonds and a broad summary on abstracts and trade literature covering the whole field of abrasives. Grits and Grinds is a trade journal w h i c h has been published by the Norton C o . since 1909. Its major contribution is i n the field of techniques for grinding operations.

LITERATURE

OF C H E M I C A L TECHNOLOGY

Patents. The patent literature of the abrasive industry is quite voluminous considering its brief span i n time. Patents may cover abrasive materials (11,21), bonds, designs, and techniques of fabricating wheels or coated abrasives. Nearly a l l relevant patents are abstracted i n Industrial Diamond Review or Ceramic Abstracts.


Other

Literature

Reports and suggestions on grinding wheel safety are available through the Grinding W h e e l Institute or from individual manufacturers. Analytical methods for abrasives are fully described i n Scott's "Standard Methods of Chemical Analysis" under the appropriate material. (Methods for analysis are also described in the chapter on "Abrasives" i n the " E n c y clopaedia of Industrial C h e m i c a l Analysis" published i n 1966 by Interscience.) Control methods used by individual manufacturers are usually kept as trade secrets. The unit processes involved i n dealing with abrasives are periodically described i n the open literature. There have been recent articles on crushing and comminution i n a number of journals ( 9 ) . Screening of abrasive grain is a special art and is frequently done w i t h silk or nylon screens. Standards for sizing of abrasive grain have been set up by the U . S. Department of Commerce. The furnacing procedures used in the industry have been reviewed by M c M u l l e n (17) and U p p e r (28). Sandmeyer and M i l l e r describe associated technology (22) (see also references 8 , 2 9 , 3 0 ) . The geographical concentration of the crude abrasive industry i n the Niagara Frontier area is reviewed by F i n l a y and U p p e r ( 9 ) . The petrology of aluminous abrasives has been considered by Baumann (1) and by Schrewelius (23). The crystallography and manufacture of silicon carbide have been considered (24,25). D a t a on hardness of abrasive materials is cited by Thibault and Nyquist (26) and by Schrewelius (23). A standard system for marking grinding wheels has been established by the industry i n the U n i t e d States and Canada. Detailed information on the system and its interpretation may be obtained either from the individual manufacturers or from the Grinding W h e e l Institute. A romanticized account of the origin and growth of the Norton Co. is given by Tymeson. This history of the largest company i n the industry provides background information not available elsewhere. The close relationship of the abrasive industry to the steel and automotive industries has been reviewed by Forchheimer (10). Large grinding wheels are used i n the pulp and paper industry to produce ground wood pulp. Recent Technology

Advances

The major recent advances may be listed as: (1) man-made diamonds, (2) sintered abrasives, (3) alumina-zirconia abrasives, (4) micro-crystalline abrasives, (5) abrasive machining, and, (6) electrolytic grinding. The appli-

cation of synthetic diamonds to grinding wheels has been rapid (2,12,31). Reviews by Bovenkerk and b y K a y may be helpful. Recently, Carborundum Co., Norton Co., and Universal Grinding W h e e l Co. have marketed snagging wheels made from sintered bauxite or alumina materials ( 5 ) . A typical material i n this field is described b y U e l t z (27). Still another new snagging abrasive depends on zirconia additions to fused alumina i n amounts ranging from 10 to 5 0 % zirconia b y weight. Such compositions are now produced b y Norton, Carborundum, Exolon, and G e n eral Abrasives. Relevant patents are b y Marshall and Roschuk (11,12) a n d Cutt (6). Micro-crystalline abrasives, so called, are extremely fine-grained materials produced b y fusion a n d chill-casting of various aluminous materials. T h e product may be cast either as small ingots or as slabs to induce the fine crystalline structure. I n general this material is most useful i n the fields of snagging and tumbling abrasives, but little information has yet been published. The new concept of abrasive machining, whereby metal is removed rapidly using grinding wheels rather than b y conventional machining methods involving tool bits, has been adequately described b y M o w r y and Smith (18). T h e n e w types of abrasives described above have helped to expand the application of grinding wheels to heavy stock removal. A n e w technique of grinding called electrolytic grinding is gradually finding application particularly on cemented carbide tools (tungsten carbide, etc.). I n this process, electrically conductive grinding wheels are used along w i t h an electrolytic metal removal process. The combination of mechanical abrasion with electrolytic solution of the anodic work-piece is said to produce better surface at a lower cost. Reinhardt and G r u n w a l d is an illustrative reference (19). Further advances i n electrolytic grinding have also been made. These apply i n particular to work on cemented carbides. Literature
