The torsional vibrations of the tool that appear in deep hole drilling processes with large length-to-diameter-ratio are the cause for a shortened tool life, degradations in the surface quality and for an insufficient process stability. Within the Priority Programme 1156 “Adaptronics for Machine Tools” an implementation concept was developed at the Institute of Machining Technology (ISF) that resulted in the manufacturing and proving of a prototypical vibration damper based on the magneto-rheological effect. In the line of the planned knowledge transfer project and based on the promising fundamental research the damper is to be enhanced to result in an adaptive solution for the single-lip deep hole drilling and the deep hole drilling using twist drills in mass production. The superior aim of the project is the realization of a low vibration deep hole drilling process and shall be reached by the interdisciplinary collaboration between the ISF and two industrial partners, the MAPAL Dr. Kress KG and the Daimler AG. All of the collaboration partners hold a verifiable expertise in the domain of the deep hole drilling and dispose of the necessary preconceptions to advance in the prototypical development of the damping system planned in this project and transform it into a solution for industrial application.

大长径比深孔钻削加工中出现的刀具扭转振动是导致刀具寿命缩短、表面质量下降和加工稳定性不足的原因。在优先计划1156“机床的Adaptronics”中，机械加工技术研究所（ISF）开发了一种实施概念，从而制造和验证了基于磁流变效应的原型减振器。在计划的知识转移项目中，基于有前途的基础研究，阻尼器将得到增强，从而为批量生产中的单唇深孔钻和使用麻花钻的深孔钻提供自适应解决方案。该项目的上级目标是实现低振动深孔钻削工艺，并将通过ISF与两个工业合作伙伴MAPAL Dr. Kress KG和Daimler AG之间的跨学科合作来实现。所有的合作伙伴都在深孔钻领域拥有可验证的专业知识，并处理了必要的先入之见，以推进本项目中计划的阻尼系统的原型开发，并将其转化为工业应用的解决方案。
