SR-20 JII type A/B

SR-20JII type A/B

Advantages & Features

The upgrade of the SR-20J II type B not only impresses with the possibility of changing the machine from sliding head to fixed headstock lathe, but also with a 25% more stable machine bed and significantly increased power when machining through stronger motors. With 5 drilling tools (front/rear) the spectrum was also extended. The back working was equipped with a Y2 axis and 8 stable tool stations (dovetail guide).
