Micro Milling Using High-Speed Spindle
The inspire AG performs various projects on current research topics, such as advanced and additive manufacturing, laser machining, Industry 4.0 and many others. One scope of research is on micro machinery. The primary research objective is to provide a reliable micro milling strategy for micro structuring electrodes. These are applied in subsequent die-sinking EDM operations. For examination, milling tools having a diameter as low as 200 µm are employed. To guarantee reasonable cutting speed and thus a stable process, a spindle speed as high as 200.000 rpm is required.
