摘要 针对传统浇注式内排屑深孔钻削系统（BTA系统或DF系统）存在着切削液消耗量大、生产成本高、污染环境及危害操作者身体健康等问题。本文是在传统的BTA内排屑深孔钻削系统基础上，增加喷雾装置，建立了亚于式内排屑深孔钻削系统。亚干式深孔钻削系统是将亚干式切削技术与深孔加工技术相结合，在BTA内排屑深孔加工系统的基础上,采用风冷雾化排屑系统代替BTA系统中的切削液排屑系统而形成的。从而实现风冷雾化切削液对刀具进行冷却润滑和排屑的功能，以减少切削液的使用及环境污染。 本次设计以亚干式内排屑深孔钻削系统为研究对象，主要设计内容有低温冷风雾化装置的设计、授油器设计以及负压抽屑装置的设计。亚干式深孔钻削系统有以下优点：系统加工过程稳定，冷却、润滑、排屑效果良好，可获得较好的刀具耐用度和内孔表面质量，同时极大地减少了切削液的用量并降低环境污染，是一种较为理想的绿色钻削工艺系。 该设计可以节约能源、降低生产成本、减少环境污染，具有良好的经济效益和社会效益。 关键词：内排屑深孔钻削 亚干式切削 雾化装置 授油器 负压抽屑 ABSTRACT The traditional cast-type method of inner-chip removal deep hole drilling system (such as BTA system or DF system) has the problems of the high cutting fluid consumption，high production costs，pollution of the environment and endangering the health of the operator and so on. In this paper，n traditional BTA escape of chips deep drilling process system foundation，increases the atomizing device，has established near-dry type deep hole drilling systemThe near-dry deep hole drilling system is that the use of compressed air atomized cutting fluid cooling and lubrication cutters in the deep hole processing with combined near-dry cutting technology and deep hole processing technology， based on the BTA inner-chips deep hole processing system，by using the air-cooled liquid escape of chips system instead of the BTA escape of chips system. Finally the air-cooled liquid with cooling and lubricating function for the cutting tool is achieved，and reduce the use of cutting fluid and environmental pollution. The near-dry deep hole drilling system was taken as object in this study，the design of the main contents of the low temperature cold wind atomization device design，coolant supply device design and suction chip removal device design. The result show that the near-dry system drill stability and have better effort in cooling lubrication，chip removal effective. The tool life and surface quality within the hole are better，at the same time，it can greatly reducing the amount of cutting fluid，the costs and the
