<p>PROBLEM TO BE SOLVED: To provide a washing device capable of efficiently and surely removing the machined powder stuck on a base pipe. SOLUTION: A high-pressure nozzle 3 is arranged at elevationθand washing liq. 4 is ejected at this angle to wash the inner peripheral surface S of the erected base pipe 1. In this way, the efficiency of the removal of the machined powder is improved since the washing liq. is ejected directly to the conrner part (b) and its peripheral part of the cutting part 1a. The value of the elevationθis set in the range of 20-45 deg..</p> |
