摘要： An abrasive article comprising abrasive grains, a porous support material and a resin bond including a coupling agent for coating said abrasive grains and said support material, said resin bond being adhered to the grains and support material with the aid of said coupling agent, the coupling agent being compatible with the resin bond, said resin bond yielding little or no volatiles during its curing so as to effect the bonding and being cured under conditions to limit production of volatiles so as to maintain the amount of interchannel porosity to less than 14% of the total volume of the abrasive article, the porosity of the article being essentially determined by said support material, whereby the article has dimensional stability during cure and superior resistance to impregnation with water after being cured. The support material may include hollow bodies, such as microbubbles of glass or alumina or the like, and the support material is used in an amount that is carefully controlled to produce the desired porosity in the abrasive article. A wide range of controlled porosity levels in the respective grinding wheels produced may be accomplished resulting in the production of wheels having superior wet strength and dimensional stability.

摘要： A coated abrasive of improved resistance to «ioading» comprising a flexible backing, a plurality of abrasive grit particles dispersed over the area of at least one surface of said backing, and at least one layer of adhesive bond ma- teriai adhering said abrasive grit particles to each other and to said backing, characterized by the fact that the outermost layer of said adhesive bond material comprises:
(a) animal giue, or a cured amino resin, or a mixture thereof in an amount of at least 40% by weight of the total adhesive bond material, exclusive of any filler; and (b) at least 0.74 grams per square meter of an additive which is (1) a mono-, di-, and tri-organyl ester of orthophosphoric acid, (2) a salt of a mono-, di-, and tri-organyl ester of orthophosphoric acid with an amine, (3) a tetraorganyiammonium sait, or (4) a soluble mixture thereof. Best results are obtained with a sizer adhesive of amino resin containing phosphate esters or their amine salts as additive.-

摘要： This invention relates to organically bonded abrasive articles that include grinding aids. It has been determined that when known grinding aids such as alkali metal sulphates and alkali metal chlorides are cofused in about eutectic proportions and added to thermoset resin bonded abrasive articles in the form of finely crushed particles having an approximate eutectic composition that an improved abrasive article results.

摘要： An improved resin bonded grinding wheel composition is shown making use of a kyanite or sillimanite or andalusite filler or mixtures thereof. More particularly the grinding wheel is a hot pressed phenol formaldehyde wheel having an alumina-zirconia abrasive with a kyanite additive therein. These wheels can be used for heavy duty metal grinding and have been determined to be especially useful for the snag grinding of titanium metal.

摘要： The grinding media is formed of a concentration of agglomerate free hard particles including at least 50 per cent by weight of the media, wherein the particles are chelated by a dispersing agent, surface treated with a surfactant, mixed with polyether polyol and polyisocyanate plus a catalyst and water and thereafter rapidly cured in a closed mold which has been preheated to a temperature exceeding 50°C and is pressurized to 4.0 to 8.5 bar. The water reacts during curing to create a polyurea linkage and release C0 2 as a blowing agent. The resulting media has a low elastic modulus with particles retained in a polyurethane-urea open cell foam binder system. The media composition may also include an inorganic filler such as glass fibers not exceeding 30 per cent by weight of the media.

摘要： Schleifaktive Füllstoffe sind ein wesentlicher Bestandteil von Schleifscheiben, die zum Trennschleifen von Materialien wie Metall, Kunststoff und Glas eingesetzt werden. Bekannte Füllstoffe sind vor allem Metallhalogenide. Besonders geeig net sind Gemische aus basischem Aluminiumchlorid und Na triumchlorid und/oder Kaliumchlorid. Solche Gemische lassen sich vor allem durch Sprühtrocknen aus wäßrigen Lösungen herstellen.

摘要： 57 A grinding tool has diamond superabrasive grains as the abrasive and a bond to retain the abrasive grains. The bond is made of organic polymer or metal and contains as a filler both a solid film-forming lubricant and finely divided diamond superabrasive grains having a grain size smaller than one-third that of the diamond superabrasive grains as the abrasive. The grinding tool of this invention is suitable for grinding a hard cutting material such as cutting tools made of titanium nitride cermet and exhibits outstanding cutting performance and durability.
