The 4 jaws are independently adjustable — each jaw moves separately to adapt to any shape. Centering takes longer (3–5 minutes with dial indicator) compared to the self-centering PO3, but the achievable precision is higher: \u003c0.01 mm with dial indicator. The PO3 is faster; the PO4 is more versatile.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eStandard DIN 6350 attachment — how to mount the chuck?\u003c\/summary\u003e\n\u003cp\u003eThe DIN 6350 flanged attachment is mounted by tightening the fixing screws evenly in a cross pattern. It takes 5–10 minutes to mount.

For gripping strong workpieces from the inside, boring jaws are used; for standard external gripping, rotating jaws are used. The jaws of the PO4 are not reversible — they are replaced with the appropriate type depending on the operation.
