Knowledge transfer for the development and optimization of bonded, vibration-damping joints for single-lip drills, extended by aspects of practicality with regard to production and use of tools

粘接是将刀具材料应用于基本刀体的另一种方法。与铜焊相比，粘接所需的时间更长。只有当相应连接的工具具有附加功能时，才能证明这是合理的。使用粘接接头，可以根据指定的减振性能或过载离合器进行设计，以避免因钻削扭矩过高而导致刀具损坏。因此，研究项目中计划的工作是关于粘接接头的设计和能力的研究。将与项目合作伙伴Guehring KG密切合作制定以下项目：识别适用于单边深孔钻井作业中使用的工具中的减震杆套连接的粘合剂系统。在保持所需精度要求的同时，在室温和烤箱温度下连接轴套连接的装置的构思、开发和构造。粘接刀具位置误差量化测量方法的研究关于粘接系统和接头尺寸的连接工艺的优化。以实验和模拟为基础获取和评估焊接工具的静态和动态行为，并将其与参考工具进行比较。机械加工中可用性的调查与评价。评估粘接接头的耐冷润滑剂性能并调查其在涂层工厂中的适用性。研究项目的目的是深入了解合适的粘接系统以及接头的几何设计，以生产具有足够强度的原型受潮工具样品。与钎焊基准工具相比，结合工具的使用能力应根据常规加工操作的要求进行验证。

Bonding is an alternative approach to apply cutting materials to basic tool bodies Compared to brazing, the time required for bonding is higher. This can only be justified if the correspondingly joined tools have additional functionalities. Using bonded joints, it is possible to design them regarding to specified vibration damping properties or as overload clutch to avoid tool breakage depending on too high drilling torques. The work planned in the research project is therefore concerned with studies on the design and capabilities of bonded joints.The following items will be worked out in close cooperation with the project partner Guehring KG: Identification of adhesive systems suitable for damping shank-sleeve connections in tools used within single-edge deep hole drilling operations. Conception, development and construction of a device for joining shaft-sleeve connections at room and oven temperature while maintaining the required accuracy requirements. Development of a measuring method for the quantification of position errors on tools with bonded joint. Optimization of the joining process with regard to the adhesive system and the dimensioning of the joint. Experimental and simulation-based acquisition and evaluation of the static and dynamic behavior of bonded tools compared to brazed reference tools. Investigation and evaluation of the usability in machining. Assessment of the resistance of the bonded joint against cooling lubricants and investigations into the applicability in coating plants.The aim of the research project is to gain insights into suitable adhesive systems as well as the geometrical design of the joint to produce prototypical damped tool samples with sufficient strength. The bonded tools operational capability shall be demonstrated under the requirements of customary machining operations in comparison to brazed reference tools.
