孕镶金刚石工具研究工作中值得探讨的问题

孕镶金刚石工具如取芯钻头、因锯片和串珠绳锯等的研制中有大量工作要做。文章仅从孕镶金刚石工具的磨损因素分析，提出孕镶金刚石工具研究工作中几个值得探讨的问题，包括金刚石的出刃值、有效工作的金刚石数量、金刚石串珠的磨损、等效石英含量、孕镶金刚石工具的冲蚀性磨损。

Problems worthed to discuss in the research work of diamond impregnated tools

A lot of works have to do in the research of diamond impregnated tools such as core drill bits,circular saws and diamond wire saws. Some problems including protrusion value of diamond grit ,amount of simultaneously active diamonds on the matrix, wear on diamond impreganted bead ,equivalent quartz content and erosive wear on diamond impre- ganted tools that worthed to discuss in the research work of diamond impregnated tools were raised from the analyzing of wear factors in diamond impregnated tools.
