When the blade wear found lower die of R0. 25 mm round 0. 013 mm, grinding amount will cause the mould surface overheating, equivalent to annealing treatment, mould become soft, reduce the life span of the mould, sharpening must increase enough coolant. After the grinding, edge sharpening stone processing, remove overly sharp line in the school, and demagnetization and oiling. When into the mould depth is not enough, will blow head height is adjusted for required size. Mold grinding quantity is certain, if to the values, the punch will be scrapped. If continue to use, easy to mold and machine damage do more harm than good.
