Piston in foremost position
R1 = Push the chuck piston to its foremost position and measure
with a depth gauge
R2 = R1 + 0.3 mm (max. + 0.5 mm)
You have to ensure that the piston can be moved to the foremost
(jaw change) position. To do this, ensure that the dimensions for
the attachment are complied with.
• Move the chuck piston (item 3) to its foremost position.
• Raise the chuck on the eye bolt in front of the spindle lug using
an assembly belt until it is flush with the center of the spindle.
• Screw the rotating threaded bush (item 15) in the chuck onto
the draw tube using the enclosed assembly key as far as this
will go.
• Tighten the chuck fastening screws (item 17) alternately.
• Check radial and axial runout at the checking edge.
• Check the actuating force is functioning and is sufficient.
• Move the cylinder into the front position. Unlock the wedge
bar (item 14) and insert the base jaws into the chuck's jaw
guidance as shown on markings 1, 2 or 3.
• Check the jaw stroke of the base jaws and that these can move
easily.
The spindle is disassembled in the same way but in the reverse
order.
