Centerless grinding is a machining process used to shape and finish cylindrical parts without the need for a fixed center. In this method, the workpiece is held between two grinding wheels: a larger wheel that performs the grinding and a smaller regulating wheel that controls the rotation and position of the part. This setup allows for continuous feeding of the material, making it efficient for high-volume production. The process is commonly used for manufacturing components like shafts, pins, and bearings. It offers advantages such as improved precision, reduced cycle times, and the ability to grind multiple parts simultaneously. Centerless grinding is particularly effective for parts that require tight tolerances and smooth finishes.
