Epäkeskokiillotuslaite

Epäkeskokiillotuslaite, also known as an orbital sander, is a power tool used for sanding wood and other materials. It operates by spinning a sanding disc in an eccentric or orbital pattern. This random orbital motion helps to prevent the formation of deep scratches and swirl marks, leading to a smoother finish compared to other types of sanders.

The tool typically consists of a motor housed in a body with a handle for grip. A sanding pad, usually circular, is attached to the eccentric mechanism, and sandpaper is affixed to this pad. The user applies the tool to the surface to be sanded, and the spinning and orbiting action removes material. Orbital sanders are often used in woodworking, carpentry, and automotive finishing for tasks such as preparing surfaces for paint, removing old finishes, and smoothing rough edges.

There are two main types of orbital sanders: random orbital sanders and standard orbital sanders. Standard orbital sanders move the sanding pad in small, perfect circles. Random orbital sanders, on the other hand, combine the circular motion with an elliptical orbit, creating a more random pattern that further minimizes visible sanding marks. This randomness makes them a popular choice for achieving a professional-quality finish. They are generally considered easier to use and control than other sanders like belt sanders.
