摘要： An abrasive article having certain minimum levels of permeability to fluids comprises about 40 to 80%, by volume interconnected porosity and effective amounts of abrasive grain and bond to carry out soft grinding and deep cut grinding operations. The high permeability to the passage of fluids and interconnected porosity provides an open structure of channels to permit the passage of fluid through the abrasive article and the removal of swarf from the workpiece during grinding operations.

摘要： A method of obtaining superabrasive grinding performance from tools employing less expensive, non-superabrasive conventional abrasive grain involves operating the conventional abrasive tool at ultra high tangential contact speed, (that is at least about 125 m/s). Such ultra high operating speeds can be achieved with segmented abrasive grinding wheels having segments formed from vitreous or resin bonded particles of aluminum oxide, silicon oxide, iron oxide, molybdenum oxide, vanadium oxide, tungsten carbide, silicon carbide and the like. The abrasive segments can be cemented to the core of the tool with an adhesive such as epoxy cement. Abrasive segments can be made to a significantly greater depth than traditional superabrasive-bearing segments, and consequently, should provide long life as well as high performance. Additionally, conventional abrasive segments are easier to true and dress and to make into intricate profiles for grinding complex shaped work pieces.
摘要翻译：使用较便宜的非超级磨料传统磨料颗粒的工具获得超研磨性能的方法包括以超高切向接触速度（即至少约125m / s）操作常规研磨工具。这种超高的操作速度可以通过具有由氧化铝，氧化硅，氧化铁，氧化钼，氧化钒，碳化钨，碳化硅等的玻璃质或树脂粘合颗粒形成的段的分段研磨砂轮来实现。研磨部分可以用诸如环氧树脂粘合剂的粘合剂粘合到工具的芯上。磨料段可以制成比传统的超级磨料承载段显着更大的深度，因此，应提供长寿命和高性能。此外，传统的磨料段更容易实现并穿着并制成复杂的轮廓以研磨复杂形状的工件。
