Polishing Machine (also called the Buffing Machine) is used to polish soft metals including copper and brass as well as plastics such as perspex. 

A polishing machine is a tool used to buff or shine surfaces, such as metal, stone, or wood, to give them a smooth and reflective finish. These machines typically use a rotating abrasive wheel or pad, along with a polishing compound, to remove scratches, marks, or imperfections from the surface of the material.

There are several types of polishing machines available, ranging from handheld devices to large industrial-grade machines. Handheld machines are commonly used for smaller projects, such as polishing jewelry or small metal parts, while larger machines are used for industrial applications, such as polishing automotive parts or aircraft components.
