Abstract
The invention belongs to the technical field of lathe spindle machining, and discloses a lathe spindle machining process facilitating machining efficiency and product quality. The lathe spindle machining process facilitating machining efficiency and product quality includes the specific steps that S1, spindle diameter processing is carried out, specifically, a to-be-machined spindle blank is obtained, the spindle blank is turned into a cylinder with the uniform diameter, the two ends of the cylinder are turned to be flat, and the machining size of 4mm is reserved in the diameter direction andthe length direction; and S2, grinding is carried out, specifically, the spindle subjected to diameter processing in the step S1 is subjected to spindle diameter grinding, the spindle is divided intoa spindle body, two groups of journals, a supporting shaft, a power shaft and an output shaft, the diameter from the spindle body to the two sides is gradually reduced, a spline is reserved on the supporting shaft, and the spline position is reserved in the cutting process. According to the lathe spindle machining process facilitating machining efficiency and product quality, the surface of the spindle is subjected to heat treatment, so that the strength and toughness are improved; and through sand blasting, stress concentration of the spindle is avoided, so that the service life of the spindle is prolonged.
Description
technical field [0001] The invention relates to the technical field of lathe spindle machining, in particular to a lathe spindle machining process beneficial to machining efficiency and product quality. Background technique [0002] The spindle is an important part of the lathe. For high-speed precision lathes, the turning accuracy of the lathe largely depends on the accuracy of the spindle system, and the accuracy of the spindle system is affected by the geometric accuracy, static and dynamic stiffness and thermal performance of the spindle system. influences. Therefore, how to improve the accuracy of the spindle system in the lathe setting is the key to the design of the lathe. The rotation accuracy of the lathe spindle is one of the main precision control indicators of the lathe, which directly affects the machining accuracy and surface roughness of the machined parts. The manufacturing process of the machine tool spindle has a key impact on the quality of the spindle. I...
