"spindle sander"的定义和意义

What is a "spindle sander"?

A spindle sander is a power tool used for sanding curved or irregularly shaped edges and surfaces. It has a rotating cylindrical drum, or spindle, covered with sandpaper, which moves up and down. The workpiece is placed against the rotating spindle, allowing for smooth sanding of curves, edges, or other detailed shapes. Spindle sanders are commonly used in woodworking, especially for finishing intricate parts, such as curves on furniture or trim pieces. They are useful for achieving a smooth, even surface on workpieces that are difficult to sand with other tools.
