摘要： A straight, thin, monolithic abrasive wheel formed of hard and rigid abrasive grains and a sintered bond including a metal component and an active metal component exhibits superior stiffness. The metal component can be selected from among many sinterable metal compositions. The active metal is a metal capable of reacting to form a bond with the abrasive grains at sintering conditions and is present in an amount effective to integrate the grains and sintered bond into a grain-reinforced composite. A diamond abrasive, copper/tin/titanium sintered bond abrasive wheel is preferred. Such a wheel is useful for abrading operations in the electronics industry, such as cutting silicon wafers and alumina-titanium carbide pucks. The stiffness of the novel abrasive wheels is higher than conventional straight monolithic wheels and therefore improved cutting precision and less chipping can be attained without increase of wheel thickness and concomitant increased kerf loss.
摘要翻译：由硬质刚性磨粒和包含金属组分和活性金属组分的烧结粘合剂形成的直的，薄的整体砂轮显示出优异的刚度。金属组分可以选自许多可烧结金属组合物。活性金属是能够在烧结条件下与磨粒形成结合的金属，并且以有效将晶粒和烧结结合在晶粒增强复合材料中的量存在。金刚石研磨剂，铜/锡/钛烧结粘结砂轮是优选的。这种轮对于电子工业中的研磨操作是有用的，例如切割硅晶片和氧化铝 - 碳化钛圆盘。新型砂轮的刚度高于传统的直式整体轮，因此在不增加车轮厚度和随之增加的切口损失的情况下，可以获得更好的切割精度并减少切屑。

摘要： A dressing blade for finishing and reconditioning new and used abrasive grinding and cutting tools has a slab-shaped shank with an extension protruding longitudinally from the shank. Superabrasive grains are disposed on the surface of the extension and held in place by a brazed metal composition. This composition is formed by brazing a powdered mixture of brazing metal components and active metal components. Specific extension configurations are provided which allow aligning the superabrasive grains in single layer arrangement for precise dressing and simple fabrication of the tool. The novel dressing tool exhibits excellent wear characteristics.

摘要： A process for metal coating diamond superabrasive particles involves heating the superabrasive particles in the presence of coat-forming powder of a metal compound under a common inert atmosphere. The metal compound contains a metal which can be thermochemically reduced by the superabrasive substance serving as the reducing agent. The process forms a chemical bond at the interface between the outer metal layer and the superabrasive particle substrate. The metal coated superabrasive particles can be hydrogen treated in situ and separated from excess coat-forming powder easily by filtration. The product particles are ideal for use in a wide variety of metal bonded cutting, machining, dressing and other abrasive tools, especially diamond film insert and single layer diamond tools.
