2. Assembly

1. Chuck conveyance to the machine spindle differs, de-

pending on the subsequent operating position. There are,
in principle, 3 mounting options:

1.1 Horizontal main spindle axis:

There are 3 x M16 conveying threads in the outer Ø of
the body 01 from size 250 onwards. One of these is used
with 1 x M16 DIN 580 ring screw (provided on site).

1.2 Vertical suspended main spindle axis:

It is recommended here that 3 x DIN 582 ring nuts (pro-
vided on site) be screwed onto the protruding thread
ends of the 3 chuck mounting screws 17 (see table for
threads).

Please note: the chuck should be mounted on
distance pieces in the machine interior to enable
removal of the 3 x DIN 582 ring nuts and allow

countering of the 3 chuck mounting screws 17 with a
hexagonal wrench.

1.3 Vertical upright main spindle axis:

There are three threads in the front face of the body 01.
Refer to the tables on page 21 and 22 for their size.. 3 x
DIN 580 ring screws (provided on site) can be screwed
into these temporarily for transportation purposes.

-- Dismount the base and interchangeable jaws. See rele-

vant section in these instructions in this respect.

-- An end position and the connecting element stroke (trac-

tion tube, traction rod) should be checked prior to moun-
ting: the forward and rear piston 05 stop is in all cases
within the chuck. Refer to the tables on page 21 and 22
for the required dimensions.

-- Move the actuation piston in the clamping cylinder for-

ward to the stop in the latter after checking the stroke
and end positions.

-- Retract the piston 05 to the stop on the adaptor plate 04.

-- Remove the 3 chuck mounting screws 17 from the body

01 (not in case of vertical suspended main spindle axis).

-- Clean the chuck mounting surfaces and check for da-

mage.

-- Clean the mounting surface for the chuck on the machine

spindle and check for radial and axial concentricity. Per-
missible errors on the test surfaces are all within 0.005
mm.

-- Connect the spindle drive to enable manual or electrical

rotation of the main spindle from left to right in short
steps.

-- Convey the chuck in compliance with the specified moun-

ting position relative to the machine spindle.

2.1.1 Horizontal or vertical upright main spindle axis:

-- Screw the entire chuck flush onto the connecting element

(traction tube, traction rod), but do not apply any consi-
derable tightening torque. This can be achieved by
holding the chuck firmly in position and rotating the
spindle slowly in an anticlockwise direction.

-- Now screw the chuck back relative to the machine

spindle until both the spindle nose (if one exists) and the
spindle flange mounting threads are in the correct posi-
tion relative to the chuck.

-- Retract the clamping cylinder by applying low force. The

chuck is drawn axially towards the spindle flange as a
result.

-- Screw the chuck to the machine spindle using the 3

chuck mounting screws 17. See table in Risk Indications
for tightening torque.

-- Check the radial concentricity of the chuck on the outer

control diameter. Max. permissible radial error is 0.01
mm. Correct if necessary by offsetting the chuck relative
to the machine spindle after partially loosening the 3
chuck mounting screws 17. Tighten the 3 chuck moun-
ting screws 17 subsequently.

2.1 Assembly of size 175:

2.1.2 Vertical suspended main spindle axis:

-- Raise the machine spindle.

-- Mount the chuck with the front face downwards (protec-

ted e.g. with timber or plastic blocks) on the tool carrier,
centred relative to the machine spindle.

-- Detach the lifting tackle if necessary and remove the DIN

582 ring nuts.

-- Lower the machine spindle carefully again, screwing the

entire chuck flush onto the connecting element (traction
tube, traction rod) without applying any considerable
tightening torque. This can be achieved by holding the
chuck firmly in position and rotating the spindle slowly in
an anticlockwise direction.

-- Raise the machine spindle far enough to allow easy in-

sertion and tightening of the chuck mounting screws 17.
