Thread cutting

Reaming/counter-sinking

MAB 485
The machine is equipped with a reversible direction of rotation
and can also be used for cutting threads.
Proceed as follows for cutting threads:
Drill the hole for the thread.
‹
Switch off the machine and select the lowest gear stage and
‹
speed.
Set the direction of rotation to clockwise (right = R) at switch
‹
(23).
Chuck the thread tap in the machine using the appropriate
‹
drill tap adapter.
Switch on the machine and set the thread tap onto the drilled
‹
hole.
Guide the machine slide down at hand lever (11) without ex-
‹
erting pressure until the desired thread length has been cut.
Switch off the machine and set the direction of rotation to
‹
anti-clockwise (left = L) at switch (23).
Switch on the machine again and allow the thread tap to
‹
come completely out of the workpiece. Then guide the ma-
chine slide upwards at hand lever (11) to avoid damaging the
start of the thread.
Thanks to its wide range of operating speeds, the machine can
also be used for reaming or counter-sinking.
CAUTION
► Observe the limits of the tools to be used for reaming and
counter-sinking given in the technical data.
