Abstract: 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.
Abstract translation: 描述了用于制造诸如砂轮和段的树脂粘合研磨制品的方法。 该方法包括制备磨粒颗粒，颗粒间隔物材料和可固化液体树脂的混合物，用混合物填充模具并在没有外部压力的情况下将混合物固化成固体制品。 以这种方式制备并含有高浓度磨粒颗粒的研磨物品在除去钢材时表现出优异的砂轮性能，同时保持切割精度，同时对所加工的钢进行冶金损伤。
