Frequently Asked Questions
PO4 4-jaw chuck Ø 200 mm — when to choose it over the PO3 3-jaw chuck?
The PO4 4-jaw chuck is necessary for: square, rectangular, asymmetrical, or irregular workpieces that cannot be centered with the 3 jaws of the PO3. The 4 jaws adjust independently — each jaw moves separately to adapt to any shape. Centering takes longer (3-5 minutes with a dial indicator) than with the self-centering PO3, but the achievable precision is higher: <0.01 mm with a dial indicator. The PO3 is faster; the PO4 is more versatile.
Camlock mount D6 DIN 55029 — how does quick mounting work?
The D6 camlock mount allows mounting and dismounting the chuck in less than 30 seconds: the locking flange is rotated a quarter turn. The cam ensures repeatability of positioning <0.01 mm with each mounting — the chuck always returns to the same angular position. Verify your lathe's mount code (D6) before purchase.
The included jaws — can they be reversed for external gripping?
The included kit contains rotating jaws (external grip) and boring jaws (internal grip). For strong internal gripping, boring jaws are used; for standard external gripping, rotating jaws. The PO4 jaws are not reversible — they are replaced with the appropriate type depending on the operation. Customer support available in Italian.
