请教老师一个问题......先谢谢了!!!!

zzm1978

<p>请问老师在c中如何编写M150 *6的螺纹孔的程式.....孔深170mm......用单颗刀片的螺纹铣刀是否可行...请做过大螺纹孔的老师傅传授一下小弟经验!!!!谢谢！!!!!</p><p>&nbsp;</p><p>小弟在此有理了~!!!!!</p><p>[em17][em17][em17][em17][em17][em17][em17][em17][em17][em17][em17][em17]</p><p>&nbsp;</p><p>[em17][em17][em17][em17][em17][em17][em17][em17][em17][em17][em17][em17]</p>

<p>就你的问题我问校长，他说，这么大的螺纹孔，谁用攻丝做呀，除非他有混了头！</p>

haitianyis

<p>呵呵， 还真没有想过如何做这么大的 </p>

pandeqi

<p>只好用螺纹铣刀了!。。。。。</p>

sunjingjing

从没尝试过.[em07]

wjp958

哈哈！聆听一下各位的声音

sunmz

<p>一，必须成型罗纹铣刀（类似镗刀）</p><p>二，轨迹螺旋插补（类似螺旋下刀）</p>

谢谢各位的帮助..仔细研究一下..!!
