L20-X
L20-X
The L20-X offers increased tool flexibility with up to 44 tools capability featuring two Y-axis.
The back working tool post utilises Y-axis control for up to 8 fixed or rotary, end-face or cross working tool holders for increased overlapped machining capability.
Another major feature is the ability to switch between use and a guide busing type and guide bushing-less type. This feature is provided as standard; the guide bushing can be fitted or removed very quickly with a simple operation.
The L20-VIII can be used as a regular guide bushing type lathe when machining long, thin workpieces and as a guide bushing-less type reducing material wastage. Increased main spindle size reduces material wastage and bar preparation requirement. Oversized options are available for up to 25mm diameter material.
