Much effort has to be done before a product within the regulated Medtech industry gets its permission. Once achieved, the machining process itself must be 100% reliable to ensure the quality of the products. Because of their criticality, the parts requirements are very high, but depending on the place of usage.
Material challenges
The materials within the Medtech industry vary from tough nickelbased alloys (e.g. bone plates), over cobalt chrome, to Inox (hip implant). Tool-costs influence the process definition, the part integrity must be aligned and furthermore the contamination by process are challenges that have to be considered. Our spindle solutions provide the possibility to monitor the process, thus maintaining the compliance and improving the process with regards to the tool usage. Additionally the spindles can be used both for milling and grinding. This enables you to machine a broad bandwith of different materials and parts.
