In mechanical manufacturing, the traditional methods adopted for finishing is not only high labor intensity, but also difficult to reach the surface roughness and requirements. The vibration grinding finishing process method is put forward, and the surface finishing experiments for spiral nozzle which is one of the important parts for aeroengine are carried. It can be seen from the experimental results that the vibration grinding process method can reach the finishing effect. Compared with the common grinding method, the vibration grinding has the features of high efficiency and high quality, etc. The vibration grinding new process method has high practical value.
