    July. 10th, we went to Middle of China for trainning the customer there
    It's a common maintain project. But the pipe with 3mm 825 incoloy cladding, see picture

    This material is very hard, it will make the cutting tool back, if the tool bit not fixed tightly.
    We feed the cutting one time every 2 rotation, and we achieve it.
    It's good experience for us.
