Description
SPECIFICATION
A grinding, honing or abrading body
This invention relates to a grinding, honing or abrading body. Such a body may be, for example what is called a "stone" (a rigid, normally somewhat brittle abrasive element mounted for metal removing movement relative to a workpiece), a grinding wheel, hone, or cut-off wheel. Such bodies are usually cured in a furnace at high temperature for a considerable time so as to produce a hard rigid highly abrasive, but easily breakable, grinding, abrading or honing body. Known grinding wheels usually include particles of abrasive material, glass powder or glass flour, and in some cases, an inert filler or extender in powder form, the whole being mixed and fused in a furnace at a high temperature, often of the order of 2500"C for a considerable time, for example three or four days.This is usually referred to as a vitrified type of structure.
Another type of grinding wheel, and some of the usual honing or grinding stones or sticks, include particles of abrasive material, a dry synthetic resin, and, in some cases, an inert filler or extender in powder form, all of which are mixed and then subjected to pressure and heat in an oven or furnace at about 350'C for three to four hours. This is referred to as a resinoid bonded structure.
A known cut-off wheel includes particles of abrasive, particles of dry plastic synthetic resin and,in some cases, an additional powdered inert filler, all mixed together and pressed onto a cut-off wheel backing member to impart strength, and with the whole being cured by pressure and heat in the same manner as referred to above in connection with the known resinoid bonded types of grinding wheel and honing stones or sticks.
All the above-mentioned known types of grinding, honing and abrading bodies are relatively brittle and are thus frequently broken during use. This is not only costly but is extremely dangerous, because detached brittle parts of such known bodies can fly away from a power-driven abrading machine at high speed, sufficient to cause injury.
It is thus an object of this invention to provide a grinding, honing or abrading body of improved characteristics, such as to reduce the possibility of breakage during a grinding, honing or abrading operation.
According to this invention a grinding, honing or abrading body comprises:- a matrix of cured or fused binding material; abrasive particles held in place in, and disseminated throughout, the cured or fused matrix, the abrasive particles being of a material substantially harder than a workpiece to be ground, honed or abraded; and reinforcing material held in place, and disseminated throughout, the cured or fused matrix, the reinforcing material being a structurally different and structurally-parameter-converting material which co-operates with the binding material to form a binder which carries the abrasive particles and which has altered structural characteristics resulting in greater tensile strength and less brittleness and breakability in the grinding, honing or abrading body.
Also according to this invention a grinding, honing or abrading body comprises:- an adhesive binding matrix having high adhesive affinity for particulate abrasive material; a quantity of hard particulate abrasive material substantially harder than a work-piece surface to be abraded thereby, the particulate abrasive material being disseminated in a cured-inplace or fused manner throughout the matrix and being firmly held thereby in a disseminated relationship so as to define a grinding, honing or abrading element having at least one surface of a required shape and surface contour carrying a plurality of particles of the abrasive material distributed along the said surface for exterior grinding, honing or abrading contact with a workpiece; the matrix also having disseminated in a cured-in-place or fused manner throughout the matrix a quantity of structurally different, reinforcing, and structural-parameter-converting, material which co-operates with the matrix effectively to form a two-phase binder carrying the abrasive particles and having altered structural characteristics resulting in greater overall tensile strength and less overall brittleness and frangibility in the grinding, honing or abrading body.
In one form, the reinforcing material may take the form of a plurality of longitudinal effective tension members co-operating with the matrix in a manner effectively changing the resultant composite tension and bending characteristics of the two-phase binder carrying the abrasive particles and thus reducing brakability and effective brittleness.
In another form, the reinforcing material may comprise a plurality of lengths (usually similar short lengths) of glass fibre (although other equivalent fibres, for example highstrength filamentary carbon fibres, may be used) and which are initially mixed into the adhesive binding matrix material before curing together with the abrasive particles, and with the whole being subsequently cured to provide the cured-in-place grinding, honing or abrading body.
In another form, the matrix may comprise an initially non-solid and subsequently hardenable or curable material, in one form, comprising synthetic resin material, for example an epoxy resin, with the matrix having adhesive affinity for the abrasive particles and the reinforcing material to make a firm, substantially unchippable and unbreakable cured junction therewith.
In another form, the reinforcing material may comprise a plurality of strands of hightensile strength (and preferably high-temperature-resistant) material in the form of thin metal strands disseminated throughout the matrix. This reinforcing material can be used when the matrix is of the type referred to immediately above, to provide what may be called a resinoid bond, and can also be used where the matrix is of vitreous type comprising an initially particulate and subsequently fused glass material in the form of powdered glass or glass "flour", which will fuse together when heated to a sufficiently high temperature and for a long enough time to result in a complete vitreous bond, locking in the abrasive particles and the high-temperature-resistant reinforcing material, such as the thin metal strands referred to above and which may comprise tungsten strands or strands of other metal materials having melting points higher than that usually required to fuse the glass particles together (for example, usually higher than 2500"C).
The reinforcing material may comprise a plurality of reinforcing elements each of larger transverse dimensions than the fibres or strands referred to above, so as to be suitable to be called fasteners or fastening elements, similar in effect to the reinforcing bars sometimes used in concrete, although a preferred form comprises a plurality of corrugated, fluted, or crimped metallic reinforcing elements or fasteners disseminated throughout the matrix.
In the resinoid bonded type of structure, high strength fibres other than glass fibres may be used, for example fibrous crystalline forms of elements such as carbon, boron, or the like. These are of the kind which have been developed in recent years by high technology processes which result in completely altered tension strength characteristics from conventional forms of carbon and boron, and which appear to be the result of the way that the material is processed or worked into the final filamentary form.
Generally speaking, the grinding, honing or abrading body of the invention may comprise a quantity of hard abrasive material harder than a workpiece surface and in the form of a plurality of particles which may vary in size from very small to quite large, according to the intended use of the body. The particle size is frequently referred to commercially as "grit" although the particle size can be defined in various ways, based on average particle dimensions or weight, or based on a screen type grading procedure. Such abrasive particles can take various forms, for example silicon carbide or aluminium oxide. The abrasive particles are disseminated throughout an adhesive binding matrix material preferably having a high adhesive affinity for the abrasive particles used.This usually takes the form of an initially powdered or semi-liquid or liquid matrix material in which the abrasive particles can be mixed, after which a hardening operation is performed to cause the matrix material to harden with the disseminated abrasive particles being then locked in place through-out the matrix and on any exposed surfaces thereof, any or all of which may then comprise a grinding, honing or abrading surface and which may be of any desired shape and/or surface contour, according to the initial forming operation. In one embodiment, in which the binding of the abrasive particles in the disseminated relationship throughout the matrix is of a resinoid type, the matrix takes the form of a synthetic resin of suitable characteristics.This resin may be initially provided in dry or powdered form, in semi-liquid or liquid form, and one preferred form comprises an epoxy resin which may be a two-part or a three-part epoxy resin in certain forms, in which at least one of the parts functions as a catalyst enhancing the resin-forming and curing operation.
In another form, the matrix may be vitreous, producing vitreous bonding of the entire abrading body and powdered glass or the like may be used in place of the synthetic resin material.
Another feature of the invention is the provision throughout the matrix of a quantity of structurally different (different from the matrix material) reinforcing, and structural-parameterconverting, material disseminated throughout the matrix and cured or fused in place therein so as to co-operate with the matrix material effectively to form a twophase binder carrying the abrasive particles, and having altered structural characteristics (altered as compared with the matrix material carrying the abrasive particles without the reinforcing material) resulting in greater overall tensile strength, greater ability to bend without breaking and consequently, less overall brittleness and frangibility in the composite grinding, honing or abrading body.
The invention will now be described by way of example, with reference to the drawings, in which:
Figure 1 is an isometric view of one embodiment of the invention, in the form of a grinding or honing "stone" or "stick", which is usually provided with a known holding structure (not shown) fastened to one portion or surface thereof so that another portion or surface thereof can be held against a workpiece to be abraded;
Figure 2 is a fragmentary, greatly enlarged, cross-sectional view of the small portion within the double-headed arrow 2 in Figure 1.
Figure 2 illustrates a resinoid bonded type of abrading body containing abrasive particles and wherein the bonding or binding matrix material is a synthetic resin reinforced with glass fibres, so that the body is less breakable than known grinding and honing stones;
Figure 3 is a reduced, isometric view of a second embodiment of the invention, in the form of a grinding wheel;
Figure 4 is a greatly enlarged, fragmentary, cross-sectional view of a modification of the
Figure 2 embodiment, and in which the adhesive binding matrix material is synthetic resin and the abrasive particles are substantially the same, but the reinforcing material is highstrength metallic fibres, for example steel or other metal having the desired structural and melting point characteristics;;
Figure 5 is generally similar to Figures 2 and 4, showing another modification, in which the binding material and the abrasive particles are substantially the same, but the reinforcing material is a high-strength-toweight-ratio filamentary material, for example carbon or boron, in either of which the molecular arrangement is modified to an apparently crystal-simulating form as a result of special working of the material and which has been found greatly to increase its strength.
This material will be referred to as strengthenhanced filamentary material, or as workprocessed filamentary material;
Figure 6 is a diagrammatic, partial, fragmentary view showing a greatly enlarged cross-sectional portion of the material of which a modified form of the abrading body of the invention may be made. It is shown before fusing of its powdered glass matrix material by application of heat and pressure in the diagrammatically shown mould.The prefused material is intended to produce a vitreous bonded type of abrading body and in practice the mould would be much larger relative to the scale of the cross-section shown in Figure 6;
Figure 7 is similar to Figure 6, but after fusing of the powdered matrix material into fused glass matrix material, which produces the final vitrified abrading body, which has modified reinforcing material because of the high temperature required for fusing the powdered glass into the solid fused glass structure shown.One high-temperature-resistant form which the reinforcing material may take is multiple tungsten strips, or reinforcing fibre equivalents, although other high-temperatureresistant materials may be used;
Figure 8 is a greatly enlarged, fragmentary, cross-sectional view generally similar to Figure 2 and is of the vitreous bonded type of Figure 7, except that the reinforcing material comprises a plurality of corrugated, fluted or crimped metallic reinforcing elements or fasteners disseminated throughout the matrix material and of high-temperature-resistant material capable of withstanding the necessary high temperatures required for fusing the glass matrix material, although this view should also be considered as representative of a variation similar to Figure 2, wherein synthetic resin is used as the bonding matrix material, thus allowing other metals or materials to be used for the reinforcing elements or fasteners because of the lower curing temperatures required in such a resinoid type of bond.
Referring to Figures 1 and 2, an abrading body 10 is a longitudinal rectangular rigid honing stone or stick. Figure 2 shows the already cured adhesive binding matrix material 1 2 which is a resin of the epoxy type, and further shows particulate abrasive material 1 4 comprising a plurality of particles of for example silicon carbide or aluminium oxide, and further shows the reinforcing material 1 6 in the form of a plurality of lengths of glass fibre, with all three components 12, 14 and 1 6 being initially thoroughly mixed for curing of the epoxy matrix material 1 2 which, for example, may comprise heating the mixture to approximately 400 in a furnace or oven and maintaining that temperature for about four hours.This will produce a relatively hard composite grinding and honing element 18, Figure 2, and which, in its fully-formed structure comprises the abrading body 10 of
Figure 1 and which has one or more grinding or honing surfaces of a required shape and a surface contour 20, Figure 1.
It has been found that 10% to 15% glass fibre in 3 mm. lengths when mixed with approximately 10% to 15% of the matrix material 12, with the remainder of the mixture (70% to 80%) comprising the abrasive particles 14, the resultant cured abrading body 10 has very satisfactory characteristics as to hardness and wear resistance comparable to known grinding stones or sticks, but that the abrading body 10 of the present invention has greatly enhanced resistance to breakage--in fact, it is difficult or almost impossible to break it during normal use. Compared with the known, readily breakable grinding stick or stone, it can be seen that the embodiment of
Figures 1 and 2 is advantageous and capable of long grinding or honing use with reduced possibility of breakage.
Figure 3 shows a grinding wheel 1 OA which may be constructed in a similar manner to the stick or stone of Figures 1 and 2, or in accordance with Figures 4, 5, 7 or 8.
Figure 4 is similar to Figure 2, but showing a variation of the reinforcing material. The strands 16' are thin metallic strands of a highstrength material, for example steel. The epoxy resin matrix material 12' and the abrasive particles 14' are similar to those of Figure 2.
Figure 5 is also similar to Figure 2 except that the reinforcing material is modified and has a plurality of strands of strength-enhanced filamentary carbon or boron 16". The binding matrix epoxy resin material 12" and the abrasive particles 14" are the same as in Figure 2.
Figures 6 and 7 illustrate another modified form of the abrading body or material, which is of a vitreous bonded type. Referring to
Figure 6, the matrix material 1 2A"' in prebonded, pre-fused form is powdered glass ("glass flour" or the like, with the abrasive particles 14"' generally similar to those of
Figure 2, although the particles 14"' are of a high-temperature-resistant material. This is possible, because conventional abrasives (silicon carbide or aluminium oxide or the like) are inherently resistant to sufficiently high temperatures to fuse the glass powder material 12A"'.
The reinforcing material 16"' comprises lengths of tungsten, although any other high melting point material having the proper structural characteristics could be used. In the embodiment of Figures 6 and 7 a mould 22 is indicated diagrammatically. It could instead comprise a two-piece or a multiple piece mould and could be closed if desired. Further since the grinding and honing material 18"' is greatly enlarged, it is obvious that the scale thereof is also greatly enlarged compared to the scale of the mould 22, which is only shown in a diagrammatic manner to illustrate the fusing step required to convert the loose non-solid material 1 8A"' from a pre-grinding element form into the fused rigid grinding element form indicated at 1 8B"' in Figure 7, which occurs after heating to a sufficiently high temperature during a curing period.For example, such temperature could be 2500"C and might last for several days. It has been found that this will produce a fully-fused form of the grinding and honing element 1 8B"' which can then be removed from the mould 22 and used for any grinding, honing, or abrading purpose. It will be found to have reduced breakability compared with known rigid vitreous type grinding or honing sticks or wheels. The fusing and/or curing operations of the several embodiments can be carried out in an oven or furnace, at pressures ranging from atmospheric pressure to much higher pressures for producing the maximum density and rigidity in the resultant abrading body.
It is also possible to use air drying, air curing or catalytic curing for rigidifying the binding matrix material. This is especially true of the resinoid type of binding and bonding material in such an abrading body.
In the vitreous bonded modification of Figure 7, the fused glass is indicated at 1 2B"'.
Figure 8 illustrates a variation of Figure 7, with the abrasive particles 14"" the same as in Figure 7 and the fused glass matrix material 1 2B"" the same as in Figure 7 (it being understood that a similar glass fusing operation has occurred), but the reinforcing material comprises a plurality of corrugated, fluted, or crimped metallic reinforcing elements 16"" of tungsten, although any other high-temperature-resistant material having a melting point higher than that required for the glass fusing operation can be used.
The shape of the elements 16"" can be modified within the scope of the reinforcing parameter-changing concept of the invention.
