A brief introduction to slender shafts

A shaft with a ratio of length to diameter greater than 25 is called a slender shaft. For example, screws and light bars on lathes. Due to the poor rigidity of slender shafts, cutting force, cutting heat and vibration during turning, it is easy to deform. And machining errors such as straightness and cylindricity occur, which is not easy to achieve shape position accuracy and engineering drawings on the surface. Technical requirements such as quality make cutting difficult. The larger the L / d value, the more difficult the turning …
