摘　　要：民用刀剪在加工过程中,由于磨削等原因,容易产生裂纹,引起刀剪刃口卷裂或产生缺口。首先分析了国内刀剪与国外产品之间的差距,简要介绍了刀剪的制造工艺,接下来针对裂纹形成原因,对刀剪磨削过程中的受力情况进行了理论分析。最后,结合3Cr13不锈钢刀剪,给出了加工过程中相应的避免裂纹产生的防范措施和方法。In grinding process of civil cutter, crack is easy to happen by the reason of grinding, and it causes gap. The difference between domestic products and foreign ones was analyzed. Then its manufacturing technics were introduced. Based on the reasons of crack, mechanical analysis in grinding process was presented. Finally, preventive measures were giver, aiming at 3Cr13 stainless steel kitchen knife.
