美国Battelle公司对刀具的低温处理法作了研究,经—195℃低温处理的刀具,一般能提高寿命1倍,有时甚至能提高4～9倍。据某大型航空工业企业测算,用于钻削Ti合金的工具钢钻头,每年耗资100万美元,采用低温处理法可降至35万美元。其中包括:新刀具购买费用的减少,重磨费用的减少,以及换刀时间的减少等。 The United States Battelle company on the tool of low temperature treatment research, by -195 ℃ low temperature processing tool, generally can improve life expectancy, and sometimes can improve 4 to 9 times. According to the estimates of a large aeronautical industry enterprise, the tool steel drill bits used for drilling Ti alloy cost about one million U.S. dollars per year, and the temperature dropped to 350,000 U.S. dollars by low-temperature treatment. Including: the purchase of new tools to reduce costs, reduce the cost of re-grinding, as well as the reduction of tool change time.
