SR-20J / JN

SR-20J / SR-20JN

Advantages & Features

The SR-20J – successor to the proven SR-20R II – has more power and additional machining possibilities in combination with a new design and improved working ergonomics and is excellent value for money.

 

SR-20JN – the fixed headstock variation of the SR-20J. Allows you to benefit from the proven star-advantages also with conventional turning. The removal of the guide bush unit, shorter remnants and even shorter set-up times result in further cost reductions in the production of short-turned parts.
