[0002] A grinder is used to grind the surface of a product to achieve the aesthetic effect of the product. Traditional grinders generally have only three motion axes: X-axis, Y-axis and Z-axis, so they can only grind the same plane. Application number 201710130831.4 An automatic grinder includes a workbench, a chuck for clamping a workpiece is provided on the workbench, and a mobile positioning mechanism for positioning an air grinding pen is also provided on the workbench; the mobile positioning mechanism includes: a clamp for clamping a vertical air grinding pen, a Z-axis direction moving control component that supports the clamp and drives the clamp to move along the Z-axis direction, an X-axis direction moving control component that supports the Z-axis direction moving control component and drives the Z-axis direction moving control component to move along the X-axis direction, and a Y-axis direction moving control component that supports the X-axis direction moving control component and drives the X-axis direction moving control component to move along the Y-axis direction. In this technical solution, the air grinding pen can only move along the three directions of the X-axis, Y-axis, and Z-axis, while the workpiece to be processed cannot move in multiple directions and dimensions, which cannot meet the processing needs well, especially when the surface to be polished is not limited to the surface in a single direction.
