我们在修复报废的卡规方面想了很多办法,都没成功,只能以小尺寸改大尺寸使用。后来在一个偶然的机会中发现了一个办法:一个新制卡规经最后工序研磨尺寸合格后,才发现空刀小了一些,于是我用薄片砂轮开了一下空刀,再校对原已合格的尺寸,却缩小了0.003。在这一现象的启发下,我去试磨报废超差的卡规,证明同样可达到缩小尺寸的目的。磨削量小,缩得少;磨削量大,就缩得的多。于是有些过去报废的卡规,经 We think of a lot of ways to repair scrap card regulations, no success, only to use small size to change the size. Later found a way by chance: a new card system by the final process after grinding the size of qualified, only to find a little empty knife, so I opened a thin wheel with an empty knife, and then proofread the original qualified Size, but reduced by 0.003. Inspired by this phenomenon, I went to test the scrap gauge card, proved the same can achieve the purpose of reducing size. Grinding a small amount of shrinkage less; grinding amount, shrink more. So some past scrapped card rules, after
