We are 6mm diameter pipe cutting hole, pipe material for the PVC material, and the nasal oxygen tube hole is almost empty, elliptical small, short axis 2.5, 4.5 axis machining tool lathe is oval, circular edges, and then pressed into elliptical shape blade fixture, cutting blade is very sharp cutting requirements, good toughness what is the most suitable, wear-resistant, steel processing, help master pointing, high reward
Use of 2Cr13 martensitic high chromium steel. This kind of steel with air quenching, Ji need heat treatment quenching, the hardness of HRC45The D512 electrode is the core of steel, you find several of these electrodes to knock coating, with 4mm of the right. If I can't find it, I can send you some to try.
