A surface grinder is a machine tool used to produce a smooth finish on flat surfaces. It works by using a rotating abrasive wheel to remove material from the workpiece, which is held in place on a magnetic or mechanical table. This process is essential in manufacturing and machining to achieve precise dimensions and surface quality. Surface grinders can be operated manually or automatically, depending on the complexity of the task. They are commonly used in industries such as automotive, aerospace, and tool-making, where high precision is required. The machine can also be used for sharpening tools and creating intricate shapes.
