【摘要】 研究了Fe－Cu－C及Fe－Cu－C－MnS烧结钢的车创加工性。通过对烧结钢车削力和刀具时用度的测试认为，采用不同原料铁粉制成的相同成分的Fe－Cu－C烧结钢车削力较大，刀具耐用度较低，因而其车削加工性较差；在Fe－Cu－C烧结钢中添加一定含量的MnS可以明显改善车削加工性。更多还原

【Abstract】 Turning machinability of Fe-Cu-C and Fe-Cu-C-MnS sintered steels arestudied in this paper, it can be found through the test of cotting force and tool liveof sintered steels that the turning machinability of Fe-Cu--C sintered steels made bydifferent iron powders are poor since their cutting foras are high and tool live arelow, MnS additive may improve their machinability.更多还原
