7.4.3 Chuck
When the hydraulic chuck has been used for a long time, there may be fine chips
accumulate inside the chuck, which can result in troubles, so the chuck should be
dismounted and cleaned once every six months.
7.4.4 Clearance
The longitudinal, traverse feed systems of the machine all employ servo motor for drive:
power from the servo motor is transferred to the ball leadscrew through the gear whose
clearance is eliminated, then, through the leadscrew to drive slide, carriage and apron to
realize longitudinal and traverse movement.
In longitudinal, traverse feed boxes there are gears whose clearance is eliminated.
Backlash of teeth should be adjusted to be small, if it is found that the backlash is too
large, it is necessary to adjust it in time. When adjusting transmitting clearance of the
gears, please refer to Fig. 13. At first, loosen all screws 1 on the gear, by help of spring 2
(it is better to apply a certain external force along spring force direction.) to eliminate
teeth backlash, then, lock the screws. Until now, adjusting working has been finished.
