The UNION PCR150 is the ideal machine tool for the machining of large components. In addition to stable heavy-duty machining, high-precision 5-sided machining of voluminous and heavy workpieces is also possible on this machine. The boring mill can be supplemented with additional units (rotary sliding table, boring head, etc.) on request and tailor fitted to your production needs.
