Information

sv-20-10-1

The SV-20R combines the fast processing ability of a traditional platen type sliding head lathe with the flexibility of a turret machine. The main spindle benefits from a gang type tool post and an 8 station turret to enable simultaneous machining operations. The turret includes an independent Z3 axis, this axis allows two different features to be machined simultaneously (Z1 + Z3) using Star’s “super-position” control mode.

Fanuc’s high specification 31i-B5 control delivers full five axis capability enabling highly complex components to be processed. The B-axis tool holders on the turret enable angular features to be machined on both the main and sub-spindle.

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.
