The L20-XII is the top of the range L20 model featuring both B-axis control and two Y-axis.
The rotary tools on the gang tool post feature B-axis control, allowing drilling and milling of angle features, and contouring with simultaneous 4-axis control. The swivel angle of 135°, from 90° to -45° enables the B-axis to be used for both front and back machining.
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-XII 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.
