[0002] Slender shafts refer to shafts with a length-to-diameter ratio greater than 25 (i.e., L / D greater than 25). Slender shafts have poor rigidity and are easily deformed by cutting forces, cutting heat, and vibration during turning, resulting in machining errors such as straightness and cylindricity. It is difficult to meet the technical requirements of shape and position accuracy and surface quality on the drawing, making cutting difficult. The larger the L / D value, the more difficult the turning process.
