SR-20RIV TYPE A

Information

The SR-20RIV Type A provides exceptional performance and versatility within the 20mm class. Up to forty one tools can be mounted including six tools on the manual B axis tool post. The flexibility of the SR-20RIV Type A 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.
