【摘要】 针对电站成套设备制造行业的零部件,在对加工条件和标准铰刀结构进行分析的基础上,进行了直刃铰刀、斜刃铰刀、螺旋刃铰刀三种刃形硬质合金铰刀的设计工作;采用三种刃形铰刀进行了干式铰削试验研究;在大量实验数据的基础上,对三种刃形铰刀在铰削力、表面粗糙度、切屑形状方面进行了对比评判,优化出使用效果最佳铰刀为螺旋刃铰刀。更多还原

【Abstract】 Based on the analysis on the machining condition and the normal reamer structure, the straight edge reamer, oblique edge reamer, and helical edge reamer are designed for the part of the heavy electricity factory. Based on the experimental data of the dry-reaming experiments with the three types of the reamers we compare the three types of reamers with reaming force, surface roughness and chip shape. The compare results show that the helical edge reamer is the best one.更多还原
