| description | PROBLEM TO BE SOLVED: To restrain a fall in cutting quality due to an electrode material sticking to the inner surface of a nozzle including the inner surface of an orifice.SOLUTION: The nozzle 6 for a plasma cutting apparatus for jetting a plasma jet to a workpiece disposed on the tip side to cut the workpiece includes a cylindrical part 6a and a tip part 6b. The cylindrical part has an internal space formed with a tapered inner surface 25b reduced in diameter toward the tip side. The tip part 6b is formed on the tip side of the cylindrical part 6a, and has the orifice 26 formed further on the tip side of the tapered inner surface 25b, and a tip surface 26a facing the workpiece. A film C made of a ceramic material is formed on the tapered inner surface 25b and on the inner surface of the orifice 26. A taper angle of the tapered inner surface 25b is 80° or more and 105° or less. |
