Description

Technical Field

[0001] The present application relates to the technical field of lathes, and in particular to a CNC vertical lathe. Background Art

[0002] In the field of modern mechanical processing, CNC vertical lathes have become key equipment for processing large rotating parts due to their advantages of high precision, high efficiency and high degree of automation. They are widely used in many important industries such as aerospace, shipbuilding, and energy equipment.

[0003] Currently, CNC vertical lathes commonly use fixed fixtures, which primarily position and clamp the workpiece through a clamping mechanism to ensure workpiece stability during machining. However, during the actual cutting process, metal cutting debris inevitably accumulates on the fixture. As machining time increases, the debris accumulates, hindering the proper functioning of the fixture's positioning elements and clamping mechanism, resulting in inaccurate positioning, uneven clamping force, and compromised workpiece clamping accuracy. Furthermore, during subsequent adjustments to the fixture, the debris can become lodged in the fixture's adjustment components, hindering smooth adjustments and potentially damaging them, increasing equipment maintenance costs. Furthermore, frequent cleaning of debris from the fixture interrupts the machining process, reducing production efficiency and severely impacting the normal operation and machining quality of the CNC vertical lathe. Summary of the Invention
