Multi-shaft fluid jet polishing machine

The utility model discloses a multi-axis fluid jet polishing machine which comprises a workbench, an R-direction rotating mechanism, an X-direction driving mechanism, a nozzle, a Z-direction driving mechanism and a Y-direction driving mechanism, wherein the workbench is used for installing a workpiece to be polished; the polishing machine further comprises an abrasive flowing device and a material extruding mechanism. Abrasive in the abrasive flowing device is conveyed to the spray head through the material extruding mechanism and sprayed to a workpiece to be polished. The polishing machine further comprises a control system. The R-direction rotating mechanism and the X-direction driving mechanism are used for driving the workpiece to be polished to rotate and translate in the X direction, and the Z-direction driving mechanism and the Y-direction driving mechanism are used for driving the spray head to move up and down in the Z direction and translate in the Y direction, so that multidirectional polishing of
