[0002] The roll grinder is a metal cutting machine tool, which consists of a bed, a headstock, a tailstock, a bracket, a longitudinal and transverse slides, a grinding head, a measuring frame and an electrical numerical control system. It is divided into five subsystems: a bearing system, a drive system, a grinding system, a measuring system and a control system. The workpiece is supported by the headstock, the tailstock and the bracket, and is driven to rotate by the headstock. The numerical control system controls the machine tool to perform multi-axis compound motion according to the mathematical model of the generatrix of the roll surface, and realizes the grinding of the roll surface metal by the grinding wheel during the motion process. The online measurement system feeds back the measurement data to the grinder control system in real time, and the control system performs closed-loop control of the machine tool, thereby completing the precision machining of the workpiece.

[0003] A search of CN210616005U discloses an adjustable center frame of a roller grinder, comprising a base and an adjustment mechanism I for driving the side pads to be extended and retracted and an adjustment mechanism II for driving the bottom pads to be extended and retracted arranged in the base, the side pads and the bottom pads being in contact with the outer circle of the roller, and the side pads and the bottom pads having the same structure.
