在模具的设计、制造和使用过程中,常会使模具局部超差或损坏,从而造成报废。近年来,我们根据模具镶嵌原理,利用线切割的工艺特点,把模具超差或损坏的局部进行镶嵌修复。修复的零件,不仅在精度和强度方面能满足质量要求,而且在外观上也不易看出修补痕迹,进一步体现了线切割加工的优点。 In the mold design, manufacture and use of the process, often make the mold partial tolerance or damage, resulting in scrapped. In recent years, according to the mold inlay principle, the use of wire cutting process characteristics, the mold aberration or damage to the local mosaic repair. Repair parts, not only in terms of accuracy and strength to meet the quality requirements, but also easy to see in the appearance of repair marks, and further reflects the advantages of wire cutting.
