2. Work safety conditions
1. application
The power chucks with an integrated pneumatic cylinder and a fixed pressure distributor (attached to the
headstock) are designed for accurate turning of very long components such as tubes with large diameters and
similar workpieces.
Chucks can work on the lathes with a spindle, ensuring mounting of two chucks on its both ends. The double
spindle configuration increases clamping force and clamping stability.
The clamping/ unclamping is performed at stopped spindle by intake/ exhaust operation into the cylinder
chambers with a compressed air.
■manufactured from high grade alloy steel, which
extends machine life while providing higher rigidity
and greater wear resistance,
■hardened and ground working surfaces ensure
longer life with maintained accuracy and
repeatability,
■rigid structure and large through-hole,
■master jaws secured against throw-off,
■master jaws and drawbar lubricated directly,
Chuck technical features: ■built-in a non-return valve maintains a constant
pressure ow in piston chambers in case of
supply pressure drop
■air pressure safety control distributor in the
clamping chambers,
■jaw stroke control device,
■plain back mounting with clamping from the
front,
■external clamping of the workpiece (rapid idle
and slow gripping stroke)
■unbalance class G 6,3.
1. Please read the instructions thoroughly before
attempting to operate on the chuck and strictly
adhere to this manual.
2. In case of fault, malfunction or damage of the
chuck, immediately stop working and contact
technical supervision.
3. Repair and overhaul of the vise must be
performed only by an appropriately qualied
person.
4. Any set-up works, maintenance and all other
application work must be carried out at
stopped spindle and disconnected pressure

Chuck structure type 2500
The power chuck consists of a high alloy steel body where the pneumatic cylinder connected with a drawbar
and three master jaws is mounted. The jaws are adapted for mounting of special hard top jaws. The jaw serration
is equal to 3/32’’ x 90°.Plain back mounting with clamping from the front. Power supply of the chuck through
a fixed pressure distributor attached on the adapter plate side.
The double-acting pneumatic cylinder use the force of the air pressure, moving the drawbar connected with jaws.
The axial force of the drawbar is transferred to the jaws through the two-angle wedge system. The compressed
air pressure is transmitted through a safety control distrubutor (mounted on the adapter plate side). A non-return
valve maintains a constant pressure flow in the piston chamber in case of supply pressure drop.

5. air distribUtion system
NOTE: The power chuck with an integrated
pneumatic cylinder use the force of the
compressed air pressure (clamping and
unclamping of the workpiece), can be
performed at stopped spindle only.
!
NOTE: The delivered airow must be clean,
undamped and correctly lubricated.
!
The compressed air that flows into the ‘clamping’
chamber of the pressure distributor causes
a deformation of the profile seal, while sealing the
connection of a distributor and chuck body, then the
air flows through a non-return valve – resulting in:
■Connection of the cylinder ‘unclamping’
chamber with the atmosphere,
■The air flows into the cylinder ‘clamping’
chamber while displacing the piston of the
position - connected permanently with the
pulling sleeve, which drives the master jaw
through the wedge system,
■The two-angle wedge system, provides jaw
working motion with two speeds:
–rapid idle stroke (long jaw stroke),
–slow motion (short jaw stroke).
■The above results in clamping of the workpiece.
The compressed air supply cut-off in the distributor
chamber is causing:
■Profiled seal returns to its original position
(seal moves out from the surface of chuck
body),
■The non-return valve cuts-off the connection
of the supplied cylinder chamber with pressure
distributor,
■The non-return valve maintains the
pressure in the cylinder chamber (after
power cut-off, the air in the chamber is
under pressure).
The workpiece is clamped and ready for machining.

■The non-return valve maintains the
pressure in the cylinder chamber (after
power cut-off, the air in the chamber is

The workpiece is unclamped.
5.2 Unclamping of the workpiece
1. jaw stroke control device
■the workpiece is clamped correctly, when the
control device arbor is in outward position,
■the control device arbor is in inward position
when:
–jaws are in the range of the rapid idle
stroke,
–jaws are in the end-point clamping range.
2. air pressure control device in the ,clamping’
chamber
■when the pressure in the ‚clamping’ chamber
is set correctly - the control device arbor is in
inward position,
■the pressure drop in the ‚clamping’ chamber
below the minimum set value (default setting of
the minimum pressure at 0,35 [MPa]) effects of
ejecting the control device arbor outwards.
The control devices should be integrated with the machine
safety control system, that prevents from operating, when
the pressure in the cylinder chamber or clamping of the
workpiece is incorrect.
The control device arbors have M6 holes designed for
clamping of any parts working with the proximity switch
devices (Fig. 1.).
Chucks type 2500 are equipped with control
devices:
NOTE: Never clamp the workpiece when the
jaws are in the range of the rapid idle stroke
or in the end-point of the clamping range (the
jaw stroke control device arbor is in inward
position).

ENGLISH
NOTE: Never place the chuck onto jaws!
!
The workstation should be equipped with the
compressed air connection, that contains a connector
block and shut-off valve (block valve).
The control system and tooling, operator should get
by himself or order.
For controlling, use the 2-way 3-position valve
located in a mid-position, connecting the chamber to
the atmosphere. (Fig. 4).

Uchwyty mechaniczne zintegrowane z cylindrem pneumatycznym i nieruchomym zasilaczem (przytwierdzonym
do korpusu wrzeciennika) są przeznaczone do mocowania długich rur o dużym przekroju średnic lub innych detali
o podobnym kształcie.
Uchwyty można stosować na tokarkach z wrzecionem umożliwiającym mocowanie dwóch uchwytów na obu jego
końcach. Układ wrzeciona z dwoma uchwytami zwiększa siłę i stabilność mocowania długich detali.
Mocowanie/ odmocowywanie odbywa się przy nieruchomym wrzecionie poprzez wypełnianie/ opróżnianie komór
cylindra sprężonym powietrzem.

Budowa uchwytu 2500
Uchwyt składa się z korpusu stalowego, w którym jest zamontowany cylinder pneumatyczny połączony z tuleją
ciągnącą i trzema szczękami podstawowymi. Szczęki są przystosowane do zamocowania szczęk górnych
twardych przestawianych. Skok ząbków wynosi 3/32’’ x 90°. Osadzenie uchytu cylindryczne z mocowaniem od
czoła. Zasilanie uchwytu poprzez nieruchomy zasilacz umieszczony od strony zabieraka.
Wbudowany cylinder pneumatyczny dwustronnego działania nadaje ruch dla tulei ciągnącej połączonej ze
szczękami. Siła osiowa tulei jest przenoszona na szczęki przez układ klinowy z dwoma kątami. Powietrze do
cylindra (przy nieruchomym wrzecionie) doprowadzane jest przez specjalny zasilacz. Uchwyty są wyposażone
w zawór bezpieczeństwa, który zabezpiecza przed spadkiem ciśnienia w komorze ciągnącej cylindra.
