摘  要:
在机械加工过程中,有很多轴类零件的长径比L/d>25。在切削力、重力和顶尖顶紧力的作用下,横置的细长轴很容易弯曲甚至失稳,因此,车削细长轴时必须改善细长轴的受力问题。此外,在切削热的影响下,细长轴的加工也容易出现变形,影响加工。文章从力和热两个方面分析了细长轴加工质量的影响因素,并结合加工实际提出了有针对性的改进措施。

摘  要:
In the machining process,there are a lot of shaft parts length diameter ratio L/d>25.Under the action of the cutting force,gravity and the tip of the top,the slender shaft is easy to bend or even lose stability.In addition,under the influence of cutting heat,the processing of slender shaft is also prone to deformation,having an impact on the processing.This paper analyzes the factors affecting the machining quality of the slender shaft from two aspects of force and heat.
