Improvement of Finished Surface Integrity of High Chromium Cast Iron in Reaming

Abstract:

With the improvement of accuracy in machine tools, ultra precision final machining has been carried out by cutting instead of grinding. In addition, JIS method for cutting fluids is revised in order to consider earth environment. However, it is very difficult for workshop to extract an optimum machining condition. The results of this study contribute to extraction of an eco-friendly machining method and reduction of running cost as well as the excellent surface integrity. This time, final machining for high chromium cast iron as the turbocharger parts of the automobile was taken up as an example which acquired the good finished surface by cutting. Namely, for the purpose of reducing the running cost, instead of honing that has been used for finishing it in the hole processing, reaming was carried out for finishing, and its practicability was investigated experimentally. As a result, it was clarified that the surface integrity was improved with the oil hole reamer and the synthetic soluble oil.
