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 table. This process is essential in manufacturing and metalworking, ensuring precision and accuracy in the dimensions of parts. Surface grinders can be operated manually or automatically, depending on the complexity of the task. They are commonly used in industries that require high levels of precision, such as automotive and aerospace. The machine can also be used for sharpening tools and creating intricate shapes in metal.
