各种现代化机器在精度、可靠性和寿命方面的要求很高,导致在机器制造业中必须采用各种新的材料(耐热钢与不锈钢、硬质合金、硅铊合金、特种陶瓷与其它的硬质和超硬的材料. 应用现有的切削工具材料不能进行新的硬质与超硬的难加工的新材料的机械加工,并不能保证达到这些零件对精度与表面光洁度提出的较高的要求,为此必须用金刚砂作为切削工具的材料. 金刚砂工具大大地扩大了机械制造业、仪表制造业和其它工业部门采用硬质和难加工材料的可能性,并可能加速机械加工过程与提高零件的精度.
Various modern machines are demanding in terms of accuracy, reliability and longevity, resulting in a variety of new materials that must be used in the machine building industry (heat-resistant steels and stainless steels, cemented carbides, silicon-thallium alloys, specialty ceramics and others Hard and super-hard materials. The use of existing cutting tool materials does not permit the machining of new hard and ultra-hard, difficult-to-machine new materials and does not guarantee that these parts will provide a higher degree of accuracy and surface finish Requires that for this purpose, emery be used as the material for the cutting tool, the emery tool greatly expands the possibilities of using hard and difficult-to-machine materials for the machine building, instrumentation and other industrial sectors and may speed up machining processes and improve parts The accuracy.
