Abstract
The importance of precision grinding processes is continually increasing in a wide range of machine industry. In particular, the demands for cylindrical and internal grinding processes with higher accuracy and higher productivity than ever before have recently increased in the machine tool and automotive industries. Within grinding machine context, the conventional cylindrical and internal grinding machine of horizontal spindle type has been in the leading position. Nevertheless, such grinding machines of horizontal type have not necessarily the most suitable structure to achieve higher accuracy and higher productivity. In order to meet such industrial requirements, it is necessary to develop a machine tool based on a new design concept. However, only few studies on an innovative grinding machine have been performed so far. Therefore, in this study, a development methodology for machine tool is proposed to realize an innovative grinding machine. Then a vertical CNC multiple-function integrated grinding machine was developed by the proposed methodology. The results of actual machining tests confirmed that the grinding machine has a remarkable performance.
