3/2-JAW CHUCKS DURO-NC As a result of the flexible 3/2-jaw platform, both round, rectangular and quadratic workpieces can be securely clamped and machined without difficulty. Thanks to ROHM's quick jaw change system, the jaws can be simply changed, turned and reused across the entire clamping range. It takes less than 60 seconds to convert the 3-jaw chuck used for the clamping of round workpieces, into a 2-jaw chuck suitable for rectangular and quadratic workpieces. This virtually eleminates wasted time typically involved with change-overs and set-ups. The use of blank jaws means that the balancing...
