2. Mounting the chuck on the machine spindle
1. Mounting the chuck on the machine spindle
1.1 Check the machine spindle or the machine-mounted
finished-machined adapter plate for radial and axial
run-out (permissible tolerance 0,005 mm to DIN 6386
and ISO 3089).
1.2 The adapter plate must be designed so that the
chuck makes full contact with the plate face.
The plate or spindle face must be perfectly flat.
1.3 Remove the locking screw (10).
1.4 Move the piston (3) fully forward.
1.5 Move to the piston of the actuating cylinder fully
forward.
1.6 Position the power chuck and insert the draw bolt (5)
into the drawbar until the chuck makes contact with
the face.
3. Maintenance
1. To maintain its reliability and
high quality, the chuck must
be lubricated at the grease
nipples at regular intervals
(see illustration).
After lubrication, move the
clamping piston several times
over its full stroke in order to
distribute the grease more
evenly. Then lubricate again.
2. Performance and clamping force must be checked
after some time, depending on the conditions of use.
The most reliable method of measuring the clamping
force is by means of a load cell.
4. Disassembly and assembly of the chuck
1. Unscrew cover (4).
2. Pull piston (3) out from the front.
3. Pull out the base jaws (2).
Clean, check an thoroughly coat all parts with Röhm
grease F 80.
5. Spare parts
When ordering spare parts, please quote the Ident. No. of the chuck and the item number or designation of the desired part
The Ident. No. will be found on the face of the chuck.
1.7 Evenly tighten the mounting screws (15) in diagonally
opposite pairs.
1.8 Further tighten the draw bolt (5) until the piston (3)
has moved 1 mm to the rear.
This ensures that the forward stroke of the
piston (3) stops inside the cylinder.
It is essential to ensure that the piston does
not come to rest inside the cover (4).
1.9 Check the operation, jaw stroke and amount of
actuating force.
1.10 Insert the locking screw (10) and check the chuck for
axial and radial run-out at the test rim.
Removing the chuck is carried out in the
reverse order.
3. Performance check: The clamping piston must
move when the lowest possible actuating pressure of
3-4 bar is applied. However, this method is not relia-
ble enough to serve as a substitute for the clamping
force measurement.
If the clamping force has dropped substantially or
if the clamping piston can no longer be moved with
ease, the chuck must be disassembled, cleaned
and relubricated.
4. Maintenance intervals: Depending on the conditions
of use, but not later than after the specified periods.
We recommend our special grease F 80.
Lubricate all lubricating points
every 20 hours of operation
heavy soling every 8 hours.
Disassemble the chuck and clean all parts
every 2000-3000 hours of operation.
4. The assembly is carried out in reverse order.
Check for correct numbering and positioning of
the base jaws (2) and piston (3).
