Programming skills for large-scale CNC lathe processing 1. The processing sequence of the parts:(1) Drill first and then flat end (to prevent shrinkage during drilling).(2) Rough machining first, then finish machining (to ensure the accuracy of the parts).(3) Machining large tolerances first and then machining small tolerances (to ensure that the surface of small tolerance…
1. The size of the workpiece is accurate and the surface finish is poorReasons: The tool tip is damaged and not sharp; the machine tool resonates and the placement is not stable; the machine tool has a creeping phenomenon; the processing technology is not good.Solution: After the tool is worn or damaged, it is not…

Pour simplifier, les centres d'usinage verticaux et les machines à sculpter et à fraiser sont essentiellement des machines d'usinage CNC de type fraiseuse. Elles sont totalement différentes l'une de l'autre en termes de capacité de traitement et d'utilisation. Les centres d'usinage verticaux sont équipés de magasins d'outils et de changeurs d'outils automatiques, ce qui leur permet non seulement de fraiser, mais aussi de percer,...
