The invention discloses sand blasting equipment. The sand blasting equipment comprises a base and a spray head and further comprises a supporting rack and a drive device. The supporting rack is arranged on the base and is used for driving the spray head to move along the X axis, the Y axis and the Z axis correspondingly, and the supporting rack comprises an X-axis supporting rod, a Y-axis supporting rod and a Z-axis supporting rod, wherein the X-axis supporting rod, the Y-axis supporting rod and the Z-axis supporting rod are connected in pairs. The drive device is connected with the supportingrack and is used for driving the X-axis supporting rod to move along the X axis, driving the Y-axis supporting rod to move along the Y axis and driving the Z-axis supporting rod to move along the Z axis. According to the sand blasting equipment, the supporting rack which is arranged on the base and is composed of the X-axis supporting rod, the Y-axis supporting rod and the Z-axis supporting rod drives the spray head to move along the X axis, the Y axis and the Z axis correspondingly, the drive device is utilized to drive the supporting rack, the sand blasting equipment can perform sand blasting on a three-dimensional workpiece, and thus the machinable range of the sand blasting equipment is broadened.
