摘要
介绍一种改进型电火花刻伤机,主要用于无损探伤对比样管的制作。分析改进型电火花刻伤机的工作原理和制作效果,探讨其对工作环境的要求、操作工艺和及时检测平底孔技术状态的刻制工艺技术。改进型电火花刻伤机实现了钢管内壁小直径、大深度标准人工伤的制作,扩展了无损探伤对比样管的制作类型。
Described in the article is a modified sinking EDM sampling machine which is mainly used to make NDT reference pipes. Discussed here are the main aspects of the said machine, including its operating principle, sampling effectiveness, working conditions as required, operation procedures, and the cutting technique for timely measuring the flat bottom hole technical status, etc. The modified sinking EDM sampling machine is capable of making small diameter, great depth standard artificial notches on steel pipe inner surface so as to get the NDT reference pipe type category enlarged.
