4.1 Mechanical maintenance

Mechanical maintenance mainly includes the maintenance of: guide rail, lead screw, synchronous belt,
synchronous belt wheel, screw and coupling. It is a must to the followings well done for maintenance:
After completing use every day, cleaning all parts of the equipment.

Oil sliding mechanism such as guide rail and lead screw with lubricant.

Make irregular check on the equipment to mainly check if there is poor contact of the joints. In case of

abnormality, timely treatment is needed to avoid causing serious problems.
The followings are detailed information concerning maintenance of each mechanical part.

4.1.1 Guide rail, Lead screw

Guide pulley and lead screw are core parts of the equipment. Their function is for direction leading and
transmission. To ensure a higher processing accuracy of the machine, higher direction leading accuracy and stable
movement of the guide pulley and lead screw are required. During operation, plenty of corrosive powder and
smoke are generated from the processed work piece. In case of long-term stay of the smoke and dust in the
surface of the guide pulley and linear shaft, the accuracy of the equipment will be greatly lowered, and corrosive
points will be formed on the surface of the linear shaft causing lifespan of the equipment shortened. To keep
normal operation of the machine and ensure processing quality, daily maintenance shall be well done.
Cleaning and maintenance of lead screw and guide rail:
Turn off the equipment, move the laser head to the right-most (or left-most), and wipe along the axis
repeatedly with cotton cloth until the axis is clean; then, move the laser head to the left-most (or right-most), and
wipe along the repeatedly with cotton cloth until the axis is clean. Finally, apply a little lubricant on the surface of
