螺旋麻花钻在生产过程中会产生部分弯曲变形，校直已变形的钻头对降低废品率十分有效。本文就对弯曲变形的钻头进行机械自动校直提出了两种方案。
Spiral twist drill in the production process will have some bending deformation, straightening the deformed drill bit to reduce the rejection rate is very effective. In this paper, the bending deformation of the drill bit mechanical automatic alignment proposed two options.
