How Does a Random Orbital Sander Work?

When it comes to sanding surfaces, the random orbital sander is a popular choice due to its ability to provide a smooth and swirl-free finish. The unique sanding pattern of a random orbital sander is what sets it apart from other types of sanders.

A random orbital sander combines the spinning motion of a disc sander with the random orbit motion of an orbital sander. The sanding disc of the random orbital sander rotates in a circular motion while also moving in an elliptical path. This dual action ensures that the sanding patterns are random, minimizing the risk of leaving visible swirl marks on the surface being sanded.

The sanding disc of a random orbital sander is attached to a pad that is free to move in an eccentric motion. This pad not only provides the random orbit motion but also acts as a cushion between the sanding disc and the surface being sanded. This helps to distribute the sanding action evenly and prevent any deep scratches or gouges in the material.

Understanding the Dual Action of a Random Orbital Sander

Let’s dive deeper into the dual action of a random orbital sander and understand how it achieves its unique sanding pattern. When the sander is turned on, the sanding disc starts rotating in a circular motion. At the same time, the pad moves in an elliptical path.

The circular rotation of the disc ensures that the sanding is continuous, allowing the sander to remove material efficiently. The elliptical motion of the pad, on the other hand, creates the random orbit. As the pad moves, it changes the angle and direction of the sanding disc, preventing the formation of visible sanding marks on the surface.

The combination of these two movements results in a random orbit sanding pattern. This pattern eliminates the possibility of sanding marks or swirls and provides a smooth and uniform finish on different types of materials, including wood, metal, and plastic.
