常见问题 FAQ
“8 倍径” 的具体含义是什么？
答：8 倍径指该系列钻头的有效钻孔深度可达钻头直径的 8 倍，属于深孔加工专用钻头，可一次性完成大深度孔位加工，减少工序与换刀次数。
内冷款钻头和外冷款有什么区别，如何选型？
答：内冷款（型号后缀带 N）内部设有冷却流道，切削液经刀柄、钻头内部直达钻尖，冷却与排屑效果更优，推荐用于深孔、难加工材料或高效率加工场景；外冷款依靠外部喷淋冷却，适合浅孔、普通材质的常规加工，采购成本更低。
该系列钻头的执行标准与核心几何参数是什么？
答：本系列执行 DIN 6535 工业标准，钻尖顶角为 140°，螺旋角为 30°，适配绝大多数数控加工中心的标准钻削工况，定心性能与切削平衡性优异。
表格中的 “推荐切削丝锥 / 挤压丝锥” 有什么作用？
答：对应规格钻头加工出的底孔，可直接匹配表格中标注的切削丝锥或挤压丝锥进行螺纹加工，无需额外计算攻丝底孔直径，可直接用于螺纹底孔工序的配套选型。
这款钻头主要适配加工哪些材料？
答：本系列为钢件加工优化设计，同时适配结构钢、合金钢、铸铁、不锈钢等常见金属材料；针对不同材质需对应调整切削转速、进给量与冷却液参数。
使用 8 倍径深孔钻有哪些工艺注意事项？
答：建议加工前确认机床内冷系统压力充足（建议 7MPa 以上）；深孔加工时可采用分级进给策略，钻入 2~3 倍孔径深度后恢复正常进给；装机后建议控制钻尖径向跳动在 0.02mm 以内，避免崩刃断钻。
钻头表面的涂层有什么作用？
答：专用涂层可提升刃口硬度与耐磨性能，降低切削摩擦系数，有效延长刀具寿命，同时可减少加工积屑瘤，提升孔壁加工表面质量。
