Hydraulic Chuck Fits Existing Machines

The new 2plus2 chuck, which uses a single conventional hydraulic cylinder, provides savings in lead time and capital outlay as it can be retrofitted to existing machines, according to manufacturer Pratt Burnerd. Chuck clamping efficiency is improved compared with conventional systems because the load is applied evenly along the jaw axis. The actuation mechanism of the jaw gives a robust, efficient mechanism, which also permits the jaws to be "t-slotted through.

Chuck clamping efficiency is improved compared with conventional systems because the load is applied evenly along the jaw axis. The actuation mechanism of the jaw gives a robust, efficient mechanism, which also permits the jaws to be "t-slotted through." Chuck rigidity is also said to be improved because the jaw is supported along its entire length. The mechanism does not need a long-stroke cylinder unlike other 2 + 2 chucks. Since the chuck does not require a special cylinder, it is simple to install and is readily exchanged with a conventional open bore chuck, allowing even greater production flexibility.
