Description

Technical Field

[0001] This utility model relates to the field of shaft parts processing technology, specifically to a high-efficiency machine tool for processing slender shaft parts. Background Technology

[0002] Machine tools for machining shaft parts are specialized equipment used to process rotating shaft parts, mainly including CNC lathes, mill-turn centers, and cylindrical grinders. These machine tools typically feature a high-rigidity bed, a precision spindle system, and a tailstock, enabling them to perform machining operations such as external turning, end facing, grooving, and threading. For special parts such as slender shafts, auxiliary support systems such as follow rests and center rests are provided. They achieve efficient and precise machining and are widely used in the automotive, machinery, and military industries.

[0003] Existing machine tools typically use a three-jaw chuck to fix the slender shaft parts during machining, followed by a tailstock with a center for a "clamp-and-support" clamping method. This reduces vibration during machining. However, after machining the part continuously for an extended period with the center in place, the center can stretch due to temperature, affecting the axial dimensions of the part. Furthermore, existing machine tools lack an automatic cleaning mechanism for filtering the circulating cutting fluid, which is located inside the machine and requires cumbersome manual cleaning. Therefore, we provide a high-efficiency machine tool for machining slender shaft parts. Utility Model Content
