the axis (guide rail lubricant); push the laser head slowly in lateral direction for several times until the lubricant is
evenly distributed on the surface of the linear axis. Clean the guide rail in the same method.
According to the frequency of equipment use, periodically (once every 15 days to two months) check if the
lubricant of the linear guide rail is sufficient; use lubricants of 32-150cst viscous force for lubrication of linear
guide rail.
Procedures:
Stop the equipment and disconnect the power supply;
Open the corresponding guard (or synchronous belt) to expose the nozzle of the linear guide slider;
Aim the filler of the grease gun at the nozzle of the slider as shown on the manual of the grease gun,
and apply oil;
Put back the guard (or synchronous belt);
Connect the power, and start the equipment.
Grease linear guide rail slider
Grease the linear guide rail slider every 70km or within three months, or else it will cause abnormal wear of
the slider and affect the precision and life of the equipment; turn off the equipment before greasing, open the
hood, and grease the slider oil nozzle with oiling gun. The recommended grease viscous force is 40~120cst.
4.1.2 Synchronous belt and synchronous pulley
① Synchronous belt and synchronous pulley are important movement parts of the equipment. It controls the
precision of motion components. The synchronous belt may be loose due to slight stretch and impact the
movement precision and sensitivity of the laser head, and thus the synchronous belt should be adjusted in
time.
Adjustment method: Use a hex wrench to loosen the mounting parts of the synchronous belt, adjust the
mounting parts of the loosened synchronous belt to tension the belt, adjust to an appropriate degree of tension,
and lock these parts. The synchronous belt should be tensioned properly; adjustment of drive motor synchronous
belt is to achieve that when pressing middle part of the synchronous belt, the sinking level is 3% to 5% of the
central distance between the belt wheel at the two ends.
Attention:
1. If to adjust the transmission belt too tight, the belt is not only easily made distortion but also cause
more severe abrasion of the bearing; if too loose, transmission accuracy and sensibility will be lowered.
2. Keep the synchronous belt away from oil, pr chemicals. Contact with acid, alkali, oil and organic solvent
is prohibited. Keep the synchronous belt dry and clean.
3. There is problem of aging with rubber of the synchronous belt. In case of serous aging (or abrasion),
timely replacing with a new one is required. Please note that synchronous belt wheel should also be
replaced if to replace the synchronous belt.
4. After using the synchronous belt for a certain period, loose belt and abrasion will also be caused, and
then timely replacement and lockup are needed. Please note that the new synchronous belt should
match with the synchronous belt wheel.
4.1.3 Fasten screws and coupling
After working for a certain period, the screws at movement joints and the coupling of the movement system
may be loosen causing low stability of mechanical movement. Therefore, during movement of the machine, you
should observe if there is abnormal sound or other abnormality with the movement parts. In case of problems
