基于数控纵切车床的细长杆件加工工艺改进

Slender Rods based on CNC Vertical Lathe Machining Process Improvement

细长杆件虽然结构简单,但机械加工难度非常大,该类零件的加工精度问题多年来难以有效解决。针对细长杆件的结构特点和其在普通车床上的加工难点,以及目前行业的加工现状,提出了一种采用新型数控纵切车床加工该类零件的新工艺方案。该工艺方案有效避免了普通车床加工该类零件时由于刀具径向切削力而造成的零件径向弯曲变形,保证了零件的加工质量。同时,该工艺方案可以极大地提高该类零件的生产效率,缩短零件加工周期,达到降本增效的目的。

According to structure characteristics and difficulties in machining slender rods, the probiems of machine precision has not been soloed for many years. In the current industry situation of processing, put forward a new technology of using numerical control lathe machining of the parts. This technology avoids the processing of ordinary lathe machining with the parts as the cutter radial cutting force caused by deformation, and ensure the machining quality of parts. At the same time, it greatly improves the parts production efficiency, shorten the processing cycle, and achieve the objective of reducing efficiency.
