Faults in common mechanical parts and failures in the maintenance feed section: The working process is normal, but the dimensional change in the X (Z) axis direction is too large. Fault analysis: 1 possible x (Z) axis servo drive failure. The screw is too large; the screw is damaged. Solution: The X (Z) axis is exchanged with the Z (X) axis servo drive. If the original X (Z) axis direction still changes too much, the Z (X) axis is normal, and the fault analysis 1 is excluded, otherwise the servo drive fault occurs. In the working mode selection, select the parameter setting, input the X (Z) axis to fill the value, if it is normal, it is the failure analysis o and replace the screw. Prone to failure: Operation error causes the tool holder to hit the workpiece and damage the screw. Tool post failure phenomenon: After the tool holder stops, the reverse rotation is not in place. Fault analysis: The sender does not send a signal. No lubrication. The positioning is loose and loose, resulting in inaccurate positioning. Solution: Check if the sender is in place. Add lubricant. Open the casing, check the locating pin, and tighten the locating pin. Prone to failure: The positioning pin is loose, resulting in inaccurate positioning. Differently cooked two C panel inch fly to the 眯 yuan cover machine foam electrical. 1r sergeant feedback sieve control control spindle code 1 (1) servo meter preparation fault phenomenon: After power-on, the "servo not ready" alarm appears. Fault analysis: Whether the 32 points of the P1C output point of the strong electric part is bright, and whether the side light switch SQ is integrated. The system part may have "xZo board" fault; servo control, whether the K relay on the unit board has action, to check the fault on the servo board. Change the equipment power board, start the machine, and eliminate the fault. There are many types of machining centers, complex structures, and many types of faults. From the fault situation of the two machining centers of the company, most of the faults appear in the power unit, input/output unit, control unit or hydraulic circuit outside the CPU. The above five methods are used alone or in combination, and generally can quickly detect and eliminate faults. In order to extend the working life of the machining center components, extend the mechanical wear cycle and prevent accidents, the regular maintenance work of the machining center is very important. Due to the different types of machining centers, the regular maintenance contents are also different, but the following common points should be noted: (1) The dust removal work should be carried out regularly in the electric control cabinet to prevent the dust from causing the insulation between the components on the circuit board to drop. Damage to the board. (2) There should be static shielding measures when plugging and unplugging the circuit board. (3) Regularly check the backup battery of the CNC system, and do not replace the battery in case of power failure to prevent data loss in the memory. (4) Regularly check the hydraulic oil and lubricating oil level and clear the fuel tank. (5) When cleaning the machine regularly, prevent chips or debris from entering the guide cleaning brush to avoid affecting the feedback system and damaging the guide rail. (6) Regularly check whether the various parts of the machine tool are in good condition according to the items specified by the machine inspection card, and whether the safety protection device is complete. If it is not bright, only the 07 point indicator of the blade is bright: if it is bright, it means that the QF, Q and QF3 may trip. It is also possible that the machine side door switch SQ is not closed: if it is not lit, it may be the QFI trip of the servo start and stop control or KA. There is no suction. If the "10 20 board" is faulty, replace the x20 board. If the servo board relay K is activated, the potentiometer Rvs, RV6 may not be adjusted, or the board. The thyristor is damaged. If the relay K1 does not operate, there may be a problem with the given voltage plug. Check if the AC180 socket is loose or disconnected. Check if the voltage to the servo unit is there and check if the relay K is damaged.
