A surface grinder is a machine tool used to create 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 parts fit together precisely and function correctly. These machines come in various sizes and types, including manual and automatic models. Surface grinders are commonly used in industries like automotive and aerospace, where precision is crucial. They help produce components like engine parts and aircraft components that require a high level of accuracy and surface quality.
