深孔加工振动断屑装置设计

Design of Vibration Chip Breaking Device for Deep Hole Processing

针对深孔加工过程中切屑形态不稳定所形成的排屑不畅问题,基于振动钻削理论,设计振动断屑装置,有效控制切削形态,保证顺利排屑。通过给刀具施加轴向周期振动,振动断屑装置可实现变切厚钻削和钻头轴向振动,使切屑易断,并在一定程度上提高了表面加工质量。通过实验探究了切屑形态与切削参数的关系,分析了振动断屑装置的最佳工作参数。

This paper focuses on deep hole machining process in cutting chip form unstable formed unsmooth chip removal problem with vibration drilling on the cutting theory of in-depth analysis of design of vibration cutting device, so as to effectively control the cutting shape and ensure chip successfully discharged. By applying an axial periodic vibration to the cutting tool, the vibration chip breaking device can realize the change of cutting thickness and the axial vibration of the drill bit, so that the chip can be easily broken, and the surface machining quality can be improved to a certain extent. Finally, the relationship between chip shape and cutting parameters is analyzed, and the optimum operating parameters of vibration chip breaking device are analyzed.
