Car slender shaft method skills
Definition of slender shaft. When the length of the workpiece is greater than 20-25 times the diameter of the straight ratio, it is called a slender shaft.Second, due to the poor rigidity of the slender shaft itself, the following problems will occur in the turning process. 1, the workpiece by cutting force, self-weight and the role of centrifugal force during rotation, will produce bending, vibration, seriously affect its cylindricity and surface roughness. 2、During the cutting process, the workpiece will be bent and deformed by heat elongation, and turning will be …
