目前,采用线切割成型,已成为模具生产的一种重要加工手段。但是,模具在线切割成型中产生裂纹乃至开裂报废的事例,时有所闻。即使一些专业化的模具生产厂,也未能彻底根除。模具在线切割成型过程中,产生裂纹的根源在于内应力。总的来看,钢材的冶金缺陷以及整个工艺过程都存在产生裂纹、开裂的危险。 At present, the use of wire cutting molding, mold production has become an important tool. However, the case of mold cutting or cracking in the case of cracking, sometimes heard. Even some specialized mold factory, but also failed to eradicate. Mold cutting process in-line, the root cause of cracks in stress. Overall, steel metallurgy defects and the entire process there is the risk of cracking, cracking.
