SR-20RIV TYPE E

Information

The SR-20RIV Type E is the latest evolution of Star’s popular SR-20RIV series. Building on the success of the Type A and Type B variants, the specification of the new Type E model has evolved to suit the requirements of a wider range of industries.

A key feature of the Type E is the programmable B-axis tool post, which offers simultaneous 4-axis control. This allows for more complex machining tasks, giving users greater production flexibility.

The machine also features Star’s proprietary cross guide structure on the gang-type tool post. This design improves rigidity by reducing load on the guide rails during cutting, supporting long-term accuracy and stable performance in demanding production environments.

Flexibility is further enhanced with the ability to switch between guide bush and non-guide bush modes depending on part length. Offering up to 41 tools on a 27-position station, the SR-20RIV Type E is designed for efficient, high-precision multi-process machining.

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.
