新型解放汽车6102发动机性能的提高,除结构的改变外,还采用了高强度、高硬度和耐磨性好的材料,如气缸套采用了含铌耐磨合金铸铁。这种材料很难加工,采用 YG 类硬质合金根本达不到工艺要求的切削用量和生产节拍。即使采用新型硬质合金(如767)刀具也无济于事。为此,我们采用陶瓷刀具加工,解决了加工问题。 The new Jiefang Automobile 6102 engine performance improvements, in addition to structural changes, but also the use of high strength, high hardness and wear resistance of the material, such as the cylinder liner with a wear-resistant alloy niobium cast iron. This material is difficult to process, the use of YG Cemented Carbide simply can not meet the process requirements of the cutting dosage and production beats. Even with the new carbide (such as 767) tool also does not make a difference. To this end, we use ceramic cutting tools to solve the processing problems.
