Complex structure, high material removal rate, extremely high requirement for effects of detail are the main features of medical parts machining.The application of hard-to-cut materials, such as titanium alloy, makes it even more difficult to realize precision machining medical parts.To meet the needs of hard-to-cut material in machining performance, efficiency and accuracy,we‘ve been focused on the research of machining technology of hard-to-cut material,and make a lot of tests and have gradually formed a set of mature and reliable technical solutions.
