磨损在金属切削加工中,对切削工具造成的损耗是惊人的。据统计,美国一年消耗的金属切削加工用的刀具,其费用达400亿美元,英国仅消耗硬质合金刀具的价值,一年就达五千万英镑。无疑,在金属切削加工中,运用摩擦学的知识,正确使用润滑冷却技术,不仅可提高加工精度和改善加工质量,而且能节约刀 Wear In metal cutting, the loss of cutting tools is staggering. According to statistics, the cost of the metal cutting tool consumed by the United States in one year amounts to 40 billion U.S. dollars. The United Kingdom only consumes the value of cemented carbide tools and reaches 50 million pounds a year. Undoubtedly, in the metal cutting process, the use of tribology knowledge, the correct use of lubrication cooling technology, not only can improve the machining accuracy and improve the processing quality, but also save knife
