Q: What is the difference between a rough turned and a precision ground steel round bar?: A rough turned steel round bar refers to a steel bar that has undergone a rough machining process to remove excess material and bring the bar to a closer approximation of its final dimensions. This process typically involves removing the outer layer of the bar through turning or other machining methods. However, the bar is not yet finished to precise tolerances and may still have slight variations in diameter or surface roughness. On the other hand, a precision ground steel round bar has undergone a secondary machining process known as grinding. Grinding is a more precise and controlled method of removing material from the surface of the bar. It involves using a grinding wheel or abrasive tool to carefully remove small amounts of material, resulting in a bar with highly precise dimensions and a smoother surface finish. Precision ground bars are typically made to meet specific tolerances and have a more consistent diameter, surface finish, and straightness compared to rough turned bars. The main difference between a rough turned and a precision ground steel round bar is the level of precision and surface finish achieved. Rough turned bars are suitable for applications where tight tolerances and surface finish are not critical, such as in certain structural or machinery components. Precision ground bars, on the other hand, are preferred when precise dimensions, tight tolerances, and a smooth surface finish are required, such as in precision machining applications or where the bar will be used as a shaft or component in critical machinery or equipment.
