可转位浅孔钻的设计与应用

通过对力的分析，提出了可转位浅孔钻的设计原则。为保证钻头背向力的平衡，推导出了旋转角β的计算公式。对可转位浅孔钻备组成零件的设计、刀片搭接量的大小、几何参数的选择、冷却方式、切削用量、使用注意事项及加工效果等作了概述。

The Design and Application of Indexable Drills for Shallow Holes

By the analysis of forces, the design principle for indexable drills for shallow holes is put forward. On the basis of balancing hack forces, the calculating formula for rotating angle β is denyed. The design of contruction parts of this drill, insert linkage size,parameter determination, cooling method, cutting data, application attentions, machining effects, etc, arc also introduced.
