NC feeder is a high-precision machine with the advantages of simple
operation, high feeding precision, low failure rate and long
service life. However, even the best machinery can not be separated
from daily maintenance. Daily maintenance and regular maintenance
are ensured. The key to long-term stability of its performance.
Daily maintenance and repair:
1. Daily lubrication and drainage of NC feeder
1) Lubrication: The gear part of the NC feed roller, coated with
gear butter, and supplemented or replaced with gear oil.
2) Drainage: After long-term operation of the NC feeder, the
three-point combination will accumulate a large amount of water to
affect its normal operation. At this time, press the button below
or rotate the water collection to remove excess water.
2. Inspection items for maintenance of NC feeder
1) Check if the NC feeder timer is working properly.
2) Remove dirt between the rollers.
3) Check for the presence of foreign matter between the gears of
the NC feeder;
4) Check if the oil pressure is normal, whether the pressure gauge
is normal, and whether the pressure indicated by the pressure gauge
is normal.
5) Check the air supply system for leaks.
6) Check if the screws and nuts combined between the mechanical
structures are loose.
7) Is the parallelism between the feeding rollers good (when the
feeding roller is closed, the upper and lower rollers are all
tightly closed).
8) Whether the NC feeder is damaged, deformed, abnormal sound or
other abnormal operation.
9) Is there any abnormality in the switches and indicators on the
operation panel of the NC feeder.
