SR-20RIV TYPE B
Information
The SR-20RIV Type B provides exceptional performance and versatility within the 20mm class. Up to forty one tools can be mounted including six tools on the B axis tool post. Fanuc’s high specification 31i-B5 control delivers full five axis capability enabling highly complex components to be processed.
The flexibility of the SR-20RIV Type B is further enhanced by its ability to switch between guide bush mode (Swiss type) and non-guide bush mode.
The powerful sub-spindle with independent 8 station platen increases overlapped machining possibilities. The Y2 axis on the sub-spindle platen allows both cross working and front facing power tools to be mounted in any station.
