铰刀的使用在我国机械制造中起着重要的作用.而历来铰刀的使用寿命不长,经济损失较大,因为制作一支铰刀无论是工艺上或是材料的使用上,要求都比较高,制作过程也比较繁杂,而一支铰刀往往做不了几个零件其精度尺寸就无法保证而报废.如果仔细计算,其经济损失是很大的.所以铰刀的改进实在是急待解决的一个问题.因此,我根据自己以往的实践和经验,自行
The use of reamers plays an important role in the manufacture of machinery in our country, but the reamer has a long service life and a large economic loss, because the production of a reamer both on the process or the use of materials, the requirements are more High, the production process is more complicated, and a reamer often can not do a few parts of the accuracy of the size can not be guaranteed and scrapped. If carefully calculated, the economic loss is great. So the reamer improvement is an urgent solution Therefore, I act on my own past practices and experiences
