| Abstract: | Aiming at the backward hand-grinding ways of controllable pitch propeller in China shipbuilding industry, a highly efficient precision grinding method is brought forward, and a four axes simultaneous grinding machine is designed which can machining complex profile with abrasive belt grinding technology by CNC. The key techniques to develop this new grinding machine is presented in detail such as heavy-duty belt grinding head, NC grinding computer aided software, etc. The application experiments of grinding and polishing propeller blade are carried out on the basis of different parameters, and the trial results provide foundation for the confirmation and application of reasonable belt grinding and polishing parameters. |
