introduction: The process range of universal cylindrical grinding machine is wide,Internal and external cylinders can be ground、Inner and outer cone、Face scheduling。But its production efficiency is low,Suitable for single piece small batch production。 The main difference between ordinary cylindrical grinding machine and universal cylindrical grinding machine in structure is:The head frame and grinding wheel frame of ordinary cylindrical grinding machine can not be adjusted Angle around its vertical axis,The spindle of the head frame cannot be turned,No internal grinding tools。therefore,The process range of ordinary cylindrical grinding machine is narrow,Only the outer cylinder and the outer cone with smaller taper can be ground。However, the structure of its main components is less hierarchical,Good rigidity,Large grinding amounts can be used,So productivity is higher
