Frequently Asked Questions
PO3 Ø 250 mm chuck — for which type of lathe and with which mounting?
D6 DIN 55029 camlock mount: assembly and disassembly in less than 30 seconds by rotating the flange a quarter turn. Positioning repeatability <0.01 mm with each assembly. Please check your lathe's mount code.
Steel vs. cast iron version — what is the concrete difference?
The steel PO3 version is 20–30% lighter than cast iron for the same diameter — it reduces start-up/braking times and vibrations at high speed, allowing for higher maximum rotation speeds. Original spare parts available with 3–5 working days shipping. Customer support in Italian available.
