Design of headstock and grinding carriage of CNC Cylindrical
Abstract: According to today's processing technology trends, CNC cylindrical grinding machine with the development of numerical control technology applications in the field of manufacturing is increasingly common, is a mechanical manufacturing mainstream equipment. Content of the research and design of the main frame and wheel frame for its first agency head frame and wheel frame bodies constitute an important part of CNC cylindrical grinding machine. Grinder headstock institutions to ensure the dimensional accuracy, surface finish and other technical parameters of the workpiece. Wheelhead part in the process of running smoothness and precision machining accuracy of the workpiece. On the basis of finished CNC cylindrical grinding machine from home and abroad on, summarized and design of this scheme. It relates to the first frame and wheel frame body part of the design, by AC servo motor drives the spindle drive belt to the grinding wheel to be processed by the object. Choice of body shell material. Using angular contact ball bearings and high-precision spindle to meet precision requirements. Nowadays trends along the manufacturing technology, through the reduction of the depth of CNC cylindrical grinding machine and a comprehensive understanding of the practice and knowledge combined.
Keywords: Cylindrical grinder NC technology High-precision
