The DURO-A RC is a power chuck with adjustable jaws (14), which is used to
clamp regularly and irregularly shaped workpieces.
It is only possible to assemble and disassemble the jaws (14) when the wedge
bar (5) is unlocked. The wedge bar (5) is locked and unlocked via the safety
key (70) included in the delivery. The jaws (14) are individually inserted and
can be locked and unlocked independently of each other.
The power chuck is attached to the machine spindle via a cylindrical holder on
the machine spindle. In the case of conical holders, an intermediate disk is re-
quired. The actuating force is generated via a clamping cylinder (electric, hy-
draulic or pneumatic).
The power chuck consists of a base body (1), piston (4), wedge bars (5),
driver, pusher (7), stop disk (13), flange (2), pressure spring (40), threaded
ring (12), bolt and conical lubricating nipple.
The piston is connected to the draw tube of the clamping cylinder via a
threaded ring (12). The piston is connected via an angled bar and a groove
with three wedge bars (5). Due to the axial movement of the piston, the
wedge bars (5) are moved and the attached jaws (14) carry out a radial
stroke.
