High performance tapping attachments with integral reversing gear
BILZ tapping attachments are of modular design and can therefore
meet the specific requirements of individual machines. They can be
used on machining centres with automatic tool changers and on
special purpose machines.
Because of the integrated maintenance free reversing gear, changes
in direction of the machine spindle are unnecessary.
The length compensation on extension, with a ball release system
which operates when in reverse, guarantees thread depths of
60,15 mm up to a speed of 4000 rpm. The GNCK tapping unit with
coolant feed, can facilitate pressures up to a maximum of 50 bar.
Precision collets ensure that the tap is securely clamped, and
additional square drivers can be utilised where high torque is being
generated, for example, when thread forming.
The torque support locks the unit relative to the spindle, thus
making automatic tool changing possible. When tool changing
takes place, the locking mechanism releases the torque support
and allows the tool changing operation to be effected.
Because of the use of the reversing gears, high tapping speeds are
possible resulting in significantly shorter cycle times compared to
conventional tapping.
