8.2 Transmissions and sTop of main spindle
You can start test run when you follow the previous steps as illustrated by the Manual. Set the speed change lever
(2) at the position 600~30, turn the speed regulation knob (3) to the middle position and push the positive and the
reverse rotation switchover lever (4) to the middle position N. Pressing the starting switch hand-lever (11) rightward
gently to lift it up, the main shaft rotates reversely and, pressing it rightward gently to push it down, the main shaft
rotates positively. Pushing it to its middle position, the main shaft stops rotation. If it is needed to put the main shaft
into a positive or a reverse rotation normally, just operate the starting
switch lever. In case of an emergency stop, stop the main shaft by
means of the foot brake. If the main shaft is needed to be started up
again after stopping by means of the foot brake, be sure to push the
starting switch hand-lever to its middle position once again before the
main shaft is re-started up.
Turn on the cooling pump switch and the cooling pump is started to
run. The flow rate of the cooling water needed is to be adjusted by
means of the cooling fluid control valve (33) (See Fig. 4-2 for details).
8.3 selecTinG main spindle speed
The main shaft speed is changed through a variable-frequency
stepless speed change device, which consists of a speed change lever
(2) and a speed regulation knob (3).
Push the high and the low speed change lever (2) to the neutral position at the middle between 3000~600 and
600~30 and it is now possible to rotate the main shaft manually.
For the purpose of safety and no damage done to the gear wheels, it is necessary to put the motor in its shutting
down state before the main shaft speed is changed. If the gear wheels are not easily engaged, push the inching
switch (9) and then push the speed change lever (2) to change
the speed of the main shaft as required (See Fig. 4-3 for details).
CAUTION: DO NOT CHANGE SPEED WHILE SPINDLE IS
RUNNING.
BE SURE ALL GEARS ARE PROPERLY ENGAGED BEFORE
STARTING.
