Centerless grinding, a machining process utilizing abrasive wheels to remove material from a workpiece, is distinguished by its support of the workpiece not by chucks or fixtures, but by a combination of a grinding wheel, a regulating wheel, and a work rest blade. This method, often employed by the Cincinnati Milling Machine Company (later Cincinnati Milacron), is highly effective for producing cylindrical parts with tight tolerances and superior surface finishes. A prime example is the high-volume production of components like bearing rollers, shafts, and pins.
This specific machining technique offers several advantages, including rapid material removal rates, high precision, and automation capabilities, leading to reduced production costs and improved part consistency. Its historical context lies in the early 20th century with the rise of mass production, where the need for efficient and accurate cylindrical grinding became crucial. The contributions of Cincinnati Milacron to the development and refinement of this technology are significant, shaping the landscape of modern manufacturing.
