在本厂，对食品罐头材料特别是ＤＩ（拉伸制罐材０在冲制加工中，由于其表面的微小缺陷而频频发生裂纹报废。为了及早发现这种缺陷，需对这些材料在全长全宽的范围内进行稳定的缺陷检测系统的开发。目前仅用较低的成本已开发出能检测５Ｘ１０￣（－４）ｍｍ￣３微小内部缺陷的系统，并于１９９１年４月在２号鼓轮式剪切机组上投入了使用，获得了预期效果。

At the factory, canned food materials, particularly DI (can stretching cans, are frequently scrapped and scrapped due to small defects on their surfaces during stamping.) In order to detect such defects early, Development of a stable defect detection system over the full width To date, a system that can detect 5X10 ~ (-4) mm ~ 3 tiny internal defects has been developed at a lower cost and was released on April 2, 1991 Drum shears put into use, get the desired effect.
