r r 切削技术基础之丝攻篇r r r r r

r r r r r r r r r r r r r r r r r r r r r r r 1.攻牙条件 r    攻牙在切削加工之中最难以切削机构解析的一种作业，攻牙条件之多，综合起来也难以解决问题的情形仍多。因此以先对攻牙作业的复杂条件、方法以及与工具品质的开连等作一般理解后，选定丝攻为妥。表8所示是攻牙条件的因素。 r    r r r r r r r r r r r r r r r r r r r r r r r r r 1—1 被切削材 r      攻牙作业上，切削材料的性质对其所用工具寿命、切出的内螺纹精度，及加工面光度等大有影响。就切削角一项而言，同时是16?程度而铜合金（黄铜、青铜）时却是3?程度的适当规定都有颇大差异。切削角以外，如有效径、硬度或表面处理等都加以考虑，对丝攻的性能也会有改善的可能。表9所是代表性的切削材质。r r r r           切削材质r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r 切削材料r r 性         质r r 螺丝攻应考虑的问题r r 低碳钢r r o质软，易起不良加工面或融着r r o切削角加大o氧化（Homo）处理有效r r 铸铜r r 中高碳钢r r o工具磨耗大r r o硬度加高r r 锰钢、工具钢r r 不锈钢r r o融着性大。o加工硬化性大r r o硬度加高r r o切屑强韧而连续。r r 铸铁r r o工具磨耗大  o扩大量小r r o为防止磨耗减少切削角，施于氮化处理r r o切屑成粉状r r o加大尺寸r r 铝r r o质软、展延性大  o易其不良加工面r r o加大切削角  o减薄刃厚r r o切屑堆积堵塞r r o无槽丝攻有效r r 铝合金r r o类似铸铁情形，且易起不良加工面r r o加大切削角  o用加大尺寸r r o无槽丝攻有效r r 铜r r o质软、展延性大   o切屑连续r r o加大切削角   o用蜗槽丝攻r r o扩大量小r r o加大尺寸     o无槽丝攻有效r r 铜合金r r o易起不良加工面（振波）r r o减少切削角   o加大尺寸r r o扩大量小r r o无槽丝攻对黄铜有效r r 热硬化性树脂r r o工具磨耗大  o扩大量小（收缩）r r o减少切削角   o加大尺寸r r o切屑成粉状r r o氮化处理r r r r r r 1—2 下孔径 r    攻牙作业的难易虽然受到下孔径大小所左右。下孔径只要在内螺纹内径公差范围内，不论采取多少，对螺丝的强度无大差，所以在允许限度内书可采取大些。下孔径一小，切屑量则增加，切削扭力增大，容易招致丝攻的磨耗或折损事故。譬如连接率由80%增至100%，切削扭力则达2倍的实例也曾有过。 r    有关公制粗牙螺纹、公制细牙螺纹、英美统一粗牙螺纹及英美细牙螺纹在JIS B1004（螺纹下孔径）规格上有下孔径的规定。在下孔径选定上的一般注意事项有下述各点： r     a）下孔径的大小对丝攻寿命、作业效率、及削成内螺纹的精度均有影响，所以内螺纹内径在许容限度的尺寸内书可能加大。 r     b）软质材料及相配长度较短而且螺丝的扭力不足情形时，下孔径要小得使攻牙无困难程度。 r     c）配合长度长者及内螺纹强度较螺铨折断强度独强（调质高抗拉力钢、不锈钢等难削材）者，其下孔径须大。 r   因上述数点，以钻头钻下孔时，普通所钻得的孔较钻头外径大（在连接率方面约能减少6～7%），所以选用钻头对实际情形有充分考虑的必要。r r r r r  r r r  r r r  r r r r r r r r r r r r r r r r r r r r r r r r r  r r r r r r r
