【摘要】 通过45号钢的切削试验,研究了国产涂层硬质合金(CN25)刀具的切削性能。实验表明,与硬质合金 YW2比较,CN25的耐用度提高系数随着切削速度的提高而提高,涂层刀具的性能必须在较高的速度范围内才能充分发挥.GN25的切削性能与国外的 KC210相近。更多还原

【Abstract】 In this paper,the cutting performances of the domestic coated-carbide (CN25)tools has been inevstigated through a series of machining tests on the steel 45(carbon content.0,45%),The results have shown that an increase in the cutting speeds will result in an augmentation of the coefficients of tool-life rise,In addition,the good performances of the coated-carbide tools could be brought into full play only under the condition of higher cutting speeds,The fact that the cutting performances of CN25 are comparable to the exotic KC210 has also been confirmed,更多还原
