Gantry machining center maintenance process

The gantry machining center mainly maintains the tool magazine. It is necessary to frequently check whether the hydraulic oil of the spindle balance bar system is sufficient, the hydraulic oil for the pressurization of the spindle tool release cylinder, if the oil level is not enough, replenish it in time, clean the taper hole of the spindle, and process iron chips. Cleaning, fixed placement of tool holders and measuring tools, etc.

The daily maintenance of the CNC gantry machining center needs to pay attention to the following 5 parts, 1. Guide rail 2. Level 3. Oil circuit 4. Air pressure 5. Hydraulic pressure

It is best to do inspections every shift, or to regularly inspect the machining center. Each gantry machining center of Jujiang CNC has undergone multiple inspections before shipment, and the sending machine debugging personnel will provide professional guidance and training. For example, regular regular cleaning of the fuel tank, some methods and details of regular lubricating oil replacement, regular precision adjustment, etc.

For the maintenance of each CNC punching machine, a daily maintenance plan should be established. The maintenance content includes: lubrication and wear of the coordinate axis transmission system, spindle lubrication, etc.; oil, water and air circuits, various temperature controls, balance systems, cooling systems, transmission belts The tightness of the relays and contactors, the cleaning of the contact heads of the relays and contactors, whether the plugs and terminals are loose, the ventilation status of the electrical cabinet, etc., and the maintenance cycle of each functional component and element (daily, monthly, half a year or irregularly).

As for the electrical faults in the maintenance of CNC punching machines, they are classified according to the nature, appearance, cause or consequence of the faults. According to the location of the fault, it can be divided into hardware fault and software fault. Hardware failure refers to the abnormal state or even damage of electronics, electrical components, printed circuit boards, wires and cables, connectors, etc. This is a failure that needs to be repaired or even replaced. The software fault generally refers to the fault generated in the PLC logic control program, which can only be eliminated by inputting or modifying some data or even modifying the PLC program. Part processing program failures are also software failures.
