Some materials of low hardness contain abrasive substances leading to rapid cutting edge wear at
high speeds. Feed rates are governed by rigidity of set-up, volume of material to be removed, surface
finish and available machine power.
THREADING
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 on the recommended size of the tap;
•
Switch off the machine (Fig. 2 - 2) and change the cutter for the tap collet and the machine
tap;
•
Switch on (Fig. 2 - 2) the machine and set the machine tap onto the drilled hole;
•
Guide the machine slide down at the handle (Fig. 1 - 2) without exerting pressure until the
desired thread length has been cut.
•
Switch off (Fig. 2 - 2) the machine and set the direction of rotation to anti-clockwise (left = L)
at switch (Fig. 2 - 1).
•
Switch on the machine (Fig. 2 - 2) again and allow the machine tap to come completely out of
the work piece. Then guide the machine slide upwards at handle to avoid damaging the
start of the thread.
COUNTERSINKING/REAMING
Thanks to its wide range of operating speeds, the machine can also be used for reaming or counter-
sinking.
