摘要
分析了BTA深孔钻工作原理和钻削特点,根据深孔加工中常见断屑、排屑困难的问题,分别从结构、刀具材料、导向块、分屑和断屑等方面进行了详细研究,提出了BTA深孔钻的结构设计要点、刀具材料的选择原则、导向块合理设计与分布原则,并简单阐述了切削速度和进给量对断屑形成的影响。
This paper analyzes the working principle and drilling characteristics of the BTA deep hole drilling. Based on a commen chip breaking and crumbling difficult issues in deep hole machining, respectively from the structure, tool material, guide block, chip crumbling, chip breaking and other aspects of the detailed studied. The structural design points of BTA deep hole drilling, the selection principle of tool materials and the guide block design and distribution rational principles are proposed. Also, the paper discusses the impact of cutting speed and feed rate on chip breaking.
