Frequently asked questions
PO3 Ø 400 mm chuck — for which type of lathe and with which mounting?
The PO3 chuck is a 3-jaw self-centering steel chuck with DIN 6350 centering. The standard DIN 6350 bolted flange mounting requires tightening the fastening screws for assembly. Check the number of holes and the bolt circle diameter of your chuck before purchasing.
The PO3 steel version vs the cast iron version — what is the concrete difference?
The PO3 steel version is 20–30% lighter than cast iron for the same diameter — it reduces start-up/braking times and vibrations at high speed. Steel allows higher maximum rotational speeds compared to cast iron. For high-speed lathes or for those who frequently work with fast changes, the steel version is the correct choice.
The included jaw set — what size pieces can this Ø 400 mm chuck clamp?
The Ø 400 mm chuck includes rotating jaws (for external clamping) and boring jaws (for internal clamping). As a reference: rotating jaws clamp workpieces from approximately 5% to 60% of the chuck's diameter. For very small workpieces compared to the chuck, consider collets; for very large workpieces, consider a chuck with a larger diameter. Customer service available in Italian.
