SERCO machining units can be attached to the outer surfaces of parts (flanges valves, etc.) with the FC 745 ChainClamping device. This means that sealing and dowel pin bearing surfaces can be completely machined. Thanks to its simple functional design, the chain can be set up by a single operator, in any position, in just a few minutes. For use with TU400, TU600, XP600 and MS 600 machines.
