BLOCKS FOR MCEPB / EPB-2F / RMA-2F［Application］
Chuck controller
required additionally Designed for holding workpieces on such machines as machining centers and NC
machine tools. Most suitable for machining workpieces by 5-face machining centers, etc.
［Features］●By securing a workpiece overhanging, the setup time on the 5-face machining
center can be shortened.
●These blocks can be used in wet operations and therefore can be used likenormal magnetic chucks.
●Since these blocks are of permanent electromagnetic type, the holding power is
not affected by power failure or cable breakage. Also since very little heat isgenerated, thermal inﬂuence on workpiece is minimal.
●The metal connector design facilitates disconnection of the power cable. (Palletchange and external setup facilitated.)

H※The chuck controller is not included.
※Turning the permanent electromagnetic blocks on and oﬀ must be limited to once per several minutes. If on/oﬀ operations are repeated frequently, the blocks may be damaged by overheat.
※The holding power is based on a test piece of SS400, 50 mm thick, ground surface held on the whole face.

Suitable for various cutting applications such as by the MC.
［Features］●As a workpiece is held on both faces, no mechanical clamping isnecessary. It can be set on the machine table easily.
●By securing a workpiece overhanging, ﬁve faces can be machined in
one chucking to improve the machining eﬃciency and accuracy.
●Since these blocks are of permanent electromagnetic type, the holding
power is not aﬀected by power failure or cable breakage. Also sincevery little heat is generated, thermal influence on workpiece isminimal.
●The power cable is of metal connector type that can be disconnectedeasily to make it suitable for pallet change and external setup.
●Several blocks can be used at the same time according to workpiecesizes and machining conditions.
