This invention discloses a high-precision grinding system for the tip of a workpiece, belonging to the technical field of grinding systems. It includes an operating table with two symmetrical side frames fixedly connected to its top; a multi-dimensional clamping assembly positioned on the upper and lower sides of the operating table; a vision-sensing grinding positioning assembly positioned on top of the operating table; and a floating grinding head assembly positioned behind the vision-sensing grinding positioning assembly. The multi-dimensional clamping assembly provides stable clamping of the workpiece during grinding; the vision-sensing grinding positioning assembly achieves truly flexible intelligent manufacturing and compares the actual grinding effect with standard requirements, realizing integrated processing and inspection; the floating grinding head assembly effectively prevents impact force from being directly transmitted to the three-axis motion system and the workpiece surface.
