广数GSK980T车床上管道循环泵轴的加工分析

对管道循环泵轴加工时存在的问题进行了分析，并相应提出了解决方法。管道循环泵泵轴采用2Cr13不锈钢材料，加工性能差，应合理选择切削参数，采用强度较高、导热系数较大的钨钴类硬质合金机夹可转位车刀，以保证粗糙度，提高生产效率。为控制泵轴外圆径向跳动不超过0．025mm，设置了心棒巧妙装夹，并将广数980T车床的普通三爪卡盘改装成液压卡盘，车削软爪夹持面，保证机床主轴与心棒基准的统一。

Machining Analysis of Shaft for Circulating Pump with GSK 980T

The machining problems of shaft for pipeline circulating pump were analyzed,and the corresponding solutions were put forward.The shaft of pump used 2Cr13 stainless steel materials,which have poor processing performances.Attentions should be specially paid to the reasonably choosing of cutting parameters.Tungsten cobalt class hard alloy,which has high strength,and large thermal conductivity,was adopted for the material of Indexable turning tool,to ensure that roughness and improve the production efficiency.F...
