Optical curve grinders are used to grind delicate complex surfaces, including straight lines, arcs, and curves. During the grinding process, the workpiece and the grinding wheel can be magnified 50 times by the optical system and projected on a screen. During operation, the operator can observe the machining of the grinding wheel along the workpiece profile on the screen at any time. The movement of the workpiece can be controlled manually or by a DC motor to achieve the purpose of processing the profile.
