Design of high precision diamond roller CNC dressing
Abstract: In recent years, CNC forming grinding technology has rapidly developed into a new processing technology and its highly efficient manner precision mechanical engineering has an extremely wide range of applications .Based on form grinding technology with great and very broad application prospects, this paper describes the characteristics and development prospects shaped grinding wheel and the analysis of the importance of maintaining high precision in grinding, but also shows the design of this project the purpose and meaning.
    The design uses a diamond roller dresser, high dresser dressing efficiency of this structure, to complete the shaping of the wheel in a very short period of time and dressing and trimming the trimming force is small, with the province to repair wear small, high precision finishing. Diamond Wheel Dresser has a high dressing efficiency, long life, easy to cool, simple structure, small size, easy installation, and other advantages. Diamond wheel trimming process less wear, very good to reduce errors in grinding wheel dressing wheel itself due to wear caused.The entire device uses a cross-roller guides, the bellows flexible coupling and angular contact ball bearings and other means to ensure accuracy. Furthermore, in order to better improve the accuracy of the device, the design also uses a high-precision encoders and closed-loop control.
