Machine tool for electrochemical precision machining

Hackert-Oschätzchen教授自2019年9月1日起担任Focus加工制造技术主席。任命Hackert-Oschätzchen教授的一个主要目的是扩大椅子的科学定位，将电化学(EC)精密加工包括在内。在马格德堡的奥托·冯·格里克大学，没有可用于EC精密加工的机床，这使得必须采购用于电化学精密加工的加工站。由于EC加工在汽车、航空航天、医疗技术以及工具和模具制造中的广泛应用，用于EC精密加工的机床包括带有附加组件的设备，这些组件使基本问题的研究能够沿着产品价值链进行应用研究。电火花精密加工是基于脉冲直流电和振荡阴极去除金属材料。特别是，由于与工艺相关的优势，如无损伤表面、高表面质量和无毛刺加工，重点放在高应力零件和精密零件的EC精密加工上，这些零件的表面不能受制造工艺的影响。除了研究EC精密加工的基本材料去除机理外，资源节约型EC技术、通过仿真实现EC精密加工的过程控制，以及EC精密加工过程的数字孪生接口和数据链将是聚焦加工制造技术主席的研究重点。

The chair for manufacturing technology with focus machining is headed since on September 1st, 2019 by Prof. Hackert-Oschätzchen. With the appointment of Prof. Hackert-Oschätzchen one main intention is to expand the scientific orientation of the chair to include electrochemical (EC) precision machining. In the Otto von Guericke University Magdeburg there is no machine tool for EC precision machining available, which makes it necessary to procure the processing station for electrochemical precision machining. Due to the wide range of applications for EC machining in automotive, aerospace, medical technology and tool and mold making, the machine applied for EC precision machining includes equipment with additional components that enable research into fundamental issues through to applied research along the value chain of products. EC precision machining is based on the removal of metallic materials with pulsed direct current and an oscillating cathode. In particular, due to the process-related advantages, such as damage-free surfaces, high surface quality and burr-free machining, the focus is on EC precision machining of highly stressed components and precision components whose surfaces must not be influenced by the manufacturing process. In addition to research on the basic material-specific removal mechanism of EC precision machining, resource-efficient EC technologies, process control of EC precision machining through simulation, as well as interfaces and data chains for digital twins of EC precision machining processes will be research priorities at the chair for manufacturing technology with focus machining.
