摘 要
该设计是设计一超声深孔钻床，利用超声震动加工深孔。振动切削与普通切削相比，在降低切削力和切削热方面有明显的效果，尤其在难加工材料的加工和精密加工中，振动切削具有普通切削无法比拟的工艺效果。因此，作为精密机械加工和难加工材料加工的一种新技术，振动切削已经逐步渗透到多种机械加工领域，振动钻削就是比较成功的应用实例。
振动钻削，即在钻头(或工件)正常工作进给的同时，对钻头(或工件)施加某种有规律的振动，使钻头在振动中切削，形成脉冲式的切削力波形，使切削用量按某种规律变化，以达到改善切削效能的目的。根据实际加工的需要，适当选择振动参数(频率v，振幅A以及频率v与工件转速n的比例关系)，可以控制切屑的大小和形状，得到满意的切屑，避免切屑堵塞。可提高生产效率几倍到十几倍，提高加工精度1—2级，且加工表面质量也有较大改善。
超声振动深孔加工钻床是利用超声振动系统对钻头施加振动，使钻头在振动中切削，使切削用两按规律变化，从而达到改善切削效能的目的。

Abstract
This design is designs a supersonic deep hole drilling machine, the use supersonic vibration processes the deep hole. The vibration cutting and the ordinary cutting compares, in reduces the cutting force and cuts the hot aspect to have the tangible effect, difficult to be processing the material especially in the processing and the precise processing, the vibration cutting has the craft effect which the ordinary cutting is unable to compare. Therefore, took the precision machinery processing and difficult to process the material processing one kind of new technology, the vibration cutting already gradually seeps to many kinds of machine-finishing domain, the vibration drills truncates compares the successful application example.
The vibration drills truncates, namely while the drill bit (or work piece) normal work to feed, (or work piece) exerts some kind of orderly vibration to the drill bit, causes the drill bit to cut in the vibration, forms the pulse -like cutting force profile, causes the cutting specifications according to some kind of rule change, achieves the improvement cutting potency the goal。According to the actual processing need, chooses the vibration parameter suitably (frequency v, oscillation amplitude A as well as frequency v with the work piece rotational speed n proportional relationship), may control the scrap the size and the shape, obtains satisfaction scrap, avoids the scrap jamming. May enhance production efficiency several times to several times, enhances the processing precision 1-2 level, also the processing surface quality also has improves greatly.
The ultrasonic vibration deep hole processing drilling machine is the use ultrasonic vibration system to the drill bit infliction vibration, causes the drill bit to cut in the vibration, causes the cutting with two according to the rule change, thus achieves the improvement cutting potency the goal.
Key words: The ultrasonic vibration, the deep hole processing, butts the lathe.
