Manual polishing lathes are machine tools used for the manual processing of surfaces. These machines are often used in precision engineering, jewelry manufacturing and watchmaking. The machine consists of a rotating turntable on which the workpiece to be machined is fixed. The grinding or polishing process is performed manually by applying the abrasive or polishing medium to the rotating turntable and pressing the workpiece onto the turntable. The pressure and speed can be controlled manually to achieve a uniform finish. Manual polishing lathes are often equipped with a variety of polishing and grinding tools, such as polishing wheels, grinding pads and grinding brushes. These tools can be made of different materials such as steel, ceramic and diamond, depending on the application and desired surface finish. Manual polishing lathes require a great deal of skill and experience to achieve a consistent, high-quality finish. However, they are often less expensive than automatic polishing and grinding machines and are well suited for machining smaller workpieces and prototypes.
