很全的螺纹钻孔和滚压直径对照表，赶紧收藏吧
很全的螺纹钻孔和滚压直径对照表，赶紧收藏吧本表所推选钻头孔径，是针对攻⽛加⼯时，能够很容易的了解钻头直径，⽽依据市售之标准钻头所选定的，在使⽤钻头的情况下，由于钻头的形状及尺⼨，精度，被钻孔之材质等，对于所钻孔的尺⼨，精度有很⼤影响，所以使⽤本表之钻孔径，若有不当之处，应实际状况适当的变更钻头直径，本表依据2级⽛制订。

翻边螺纹孔的尺寸见DIN 7952-T1用冲孔标记不能确定预加工孔。
按DIN7952-B1的翻边孔只能用成型冲压或钉孔法 生产。
说明板材冲孔翻边的尺寸稳定性受很多实际因素的影响。
因此不可能涉及精确的尺寸，特别是 绝无技术的联合影响阻碍技术的发展。
因此与材料有关的规定就不计了。
但为了对制造翻边孔重要的资料应无错误，所以规定了预加工孔的推荐值。
这些推荐值与 翻边螺纹孔按DIN 7952-B1的内径d2有关，该螺纹内径公差带为5H 。
预加工孔直径的推荐值是计算的，并考虑初始材料体积与翻边加工后材料相等。
这个条件 满足等式：其中符号意义：d2 螺纹内径(成品尺寸) d4 预加工孔直径d5 翻边圈直径平均值h ’ 减少的翻边圈高度(考虑由于拉深螺纹内径的体积减少) 所 板材壁厚以前所用的螺纹M2.2和M2.6是在比较DIN 13 B1时ISO/R261中没有的螺纹尺寸。

用冲孔标记不能确定预加工孔。
按DIN7952-T1的翻边孔只能用成型冲压或钉孔法生产。
翻边螺纹孔的尺寸见DIN 7952-T1
用冲孔标记不能确定预加工孔。
按DIN7952-B1的翻边孔只能用成型冲压或钉孔法 生产。
说明
板材冲孔翻边的尺寸稳定性受很多实际因素的影响。
因此不可能涉及精确的尺寸，特别是 绝无技术的联合影响阻碍技术的发展。
因此与材料有关的规定就不计了。
但为了对制造翻边孔重要的资料应无错误，所以规定了预加工孔的推荐值。
这些推荐值与 翻边螺纹孔按DIN 7952-B1的内径d2有关，该螺纹内径公差带为5H 。
预加工孔直径的推荐值是计算的，并考虑初始材料体积与翻边加工后材料相等。
这个条件 满足等式：
其中符号意义：
d2 螺纹内径(成品尺寸) d4 预加工孔直径
d5 翻边圈直径平均值
h ’ 减少的翻边圈高度(考虑由于拉深螺纹内径的体积减少) 所 板材壁厚
以前所用的螺纹M2.2和M2.6是在比较DIN 13 B1时ISO/R261中没有的螺纹尺寸。
