1、 Inspection items for accuracy maintenance of gantry machining center
1. After starting up, it is necessary to preheat for about 10 minutes before processing. For machines that are not used for a long time, the preheating time shall be extended.
2. Check whether the oil circuit is unblocked
3. Before shutdown, place the workbench and saddle at the center of the machine (move the three-axis travel to the center of each axis travel).
4. Longmen machining center insists on cleaning.
2、 Daily protection and maintenance of Longmen machining center
1. Check the lubricating oil level of the gantry machining center to ensure that the CNC machining center is lubricated. It is recommended to use T68 # guide rail lubricating oil.
2. Check whether the coolant in the coolant tank of the gantry machining center is satisfactory and cannot be added in time.
3. Check the oil level of the pneumatic triplet of the gantry machining center, which is about 2 / 3 of the height of the entire oil pipe. The water and gas in the pneumatic triplet filter tank shall be discharged by the drain switch every day.
4. Check the air pressure of the gantry machining center, loosen the adjustment knob, and adjust the pressure according to the principle of right-hand pressurization and left-hand depressurization, which is generally set at 5 ~ 7kg / cm2. Generally, the pressure switch is set to 5kg / cm2. When it is lower than 5kg / cm2, the alarm will be given. The system will give an alarm of "low air pressure". After the pressure rises, the alarm information will disappear.
5. Check whether the air blowing of the taper hole in the main shaft of the gantry machining center is normal. Wipe the taper hole in the main shaft with clean cotton cloth and spray light oil.
6. Clean the tool arms and tools of the tool magazine of the gantry machining center, especially the tool jaws.
7. Clean the exposed limit switches and bumps of the gantry machining center.
8. Eliminate cutting and oil stains on the working table of gantry machining center, inside the CNC machining center and on the three-axis elastic shield.
9. Check whether all signal lights and abnormal alarm warning lights of the gantry machining center are normal.
10. Check the oil pressure unit pipe of the gantry machining center for leakage.
11. The gantry machining center carries out cleaning after the completion of daily machining tasks.
12. Adhere to the regular environment around the machine.
13. When the machine tool is not used for a long time, it must be thoroughly cleaned, and lubricating oil must be applied to the guide rail surface of the machine tool to prevent rust.
