摘要： A grinding and cutting process and articles employing an effective amount of a grinding aid, typical of which is sodium nitrite which, when applied to the abradant or cutting edge of a tool, accelerates the modification of a metal workpiece and prolongs the useful life of the tool. The grinding aids of this invention are compounds free of sulfur and/or halogen and having a melting point in the range of 70.degree. F. to 1000.degree. F., a decomposition temperature at least 100.degree. F. above the melting temperature and a latent heat of melting greater than 10 cal/gm.

摘要： A process is described for manufacturing resin bonded grinding articles such as grinding wheels and segments. The process comprises preparing a mixture of abrasive grain particles, particulate spacer material and a curable liquid resin, filling a mold with the mixture and curing the mixture to a solid article in the absence of external pressure. Grinding articles prepared in this manner and containing high concentrations of abrasive grain particles exhibit superior grinding wheel performance in rate of stock removal with no metallurgical damage to the steel being worked upon while maintaining precision of cut.

摘要： A WORM-SHAPE OR SCREW-SHAPE HONE, FOR HONING GEAR COMPACTED AND BOUND SOLID PARTICLES, FOR EXAMPLE FUELS TEETH, HAS THE TOOTH PROFILE OF THE BASIC RACK AT ITS NORMAL SUCH AS BARBECUE BRIQUETTES AND FIREPLACE LOGS MADE FROM PARTICULATE COMBUSTIBLE MATERIALS SUCH AS SAWDUST, WOOD PLANE. THE HONE IS FORMED BY MOLDING SYNTHETIC POLYMERS IN WHICH THERE ARE DISPERSED ABRASIVE PARTICLES, TO PROFLOUR, CHARCOAL, AND COKE IN WHICH THE BINDER FOR THE COM: BUSTIBLE MATERIALS IS CELLUSOSE FIBERS DERIVED FROM PAPER VIDE A SHORE HARDNESS OF 15*-75* AND A YOUNG''S MODULUS 0.5-70X10**3 KG./CM.2. THE HONE IS ENGAGED WITH THE GEAR PULP. TO BE FIBISHED AND IS ROTATED BY A MOTOR WITH THE HONE DRIVING THE GEAR. DURING HONING OF THE GEAR, THE HONE IS FED PARALLEL TO THE AXIS OR TOOTH TRACE OF THE GEAR OVER THE

WHOLE FACE WIDETH OF THE GEAR. THE POLYMER MATERIAL MAY COMPRISE A CO-CURED BLEND OF POLYURETHANE RUBBER AND EPOXY RESIN HAVING A SUITABLE FLEXIBILITY, GOOD RESILIENCY AND HIGH ABRASION RESISTANCE, AND THE ABRASIVE PARTICLES MAY COMPROSES ALUNDUM OR CARBORUNDUM, THE ABRASIVE PARTICLES BEING EXPOSED AT THE WORKING SURFACE OF THE HONE.

摘要： THE MANUFACTURE OF ABRASIVE ARTICLES IS FACILITATED BY ENCAPSULATING ABRASIVE GRAINS WHICH ARE COATED WITH A BINDER I A THIN SHELL OF A CURED POLYISOCYANATE/HYDROXYL FUNCTIONAL POLYMER SYSTEM. THE ENCAPSULATED ABRASIVE GRAINS ARE DRY AND TACK-FREE AND MAY BE STORED AND PROCESSED IN THE TACK-FREE FORM INCLUDING PROCESSING THROUGH A PRESSING OPERATION TO FORM GREEN ABRASIVE ARTICLES SUITABLE FOR BAKING OR FIRING.

摘要： Extruding a plastic abrasive mix through a multi-hole die adapted to combine emerging strands of the mix into a single strand whereby the strands move at the same linear rate. The single strand is cut into large pellets of uniform length, after which they are divided into smaller pellets corresponding to the original number, size, and shape of each of the combined strands and cured.
