As a kind of automatic mechanical production equipment with high technology content, CNC carpenter engraving machine is essential to maintain and protect it in daily operation, which can better protect the performance of equipment. Here Jinan Shunhuan CNC Carpenter Engraving Machine Factory also gives a brief introduction to some necessary maintenance and protection knowledge.
First, the computer carpenter engraving machine runs continuously for 10 hours or less every day to ensure the cleaning of the cooling water and the normal operation of the pump. The water spindle motor must not be dehydrated, and the cooling water should be replaced on time to prevent the water temperature from being too high. In the winter, if the working environment temperature is too low, the water inside the water tank can be replaced with antifreeze.
Second, each time you use the computer engraving machine, you should pay attention to the finishing, be sure to clean the dust on the platform and transmission system, and regularly (weekly) lubricate the transmission system (X, Y, Z three axes). (Note: X, Y, Z three-axis polished rods are maintained with oil; high-speed butter is added to the screw; in winter, if the operating environment temperature is too low, the screw, polished rod (square rail or circular guide) should be cleaned with gasoline first. Then add the oil, otherwise the resistance of the machine transmission part will be too large and the machine will be misaligned.)
Third, the maintenance of the electrical equipment to see is, must intercept the power supply, until the monitor has no display and the main circuit power indicator light subsides before proceeding.
Protection of computer engraving machine:
Correction of computer carpenter engraving machine parameters: manufacturer parameter correction.
Workbench travel: (depending on the model of the machine)
System parameters: The first four items are selected on the basis of acquiescence.
Motor parameters: If the lead is 10 then 0.0062
If the lead is 5 then 0.003125
Take-off frequency: 300
Z axis maximum speed: 1000
Uniaxial acceleration: 400
Curved acceleration: 300
Repair of computer engraving machine:
When the computer engraving machine can't work normally, it may be a problem with its internal components or other reasons. The following is a general introduction to the problems that are often presented.
(1) One of the three axes cannot be moved. At this moment, check whether the corresponding drive block of the corresponding axis is damaged. To view the method, use the replacement method: unplug the aviation plug corresponding to the fixed shaft and insert it into the drive corresponding to the other active shaft.
(2) If the non-moving axis moves normally after the exchange, it can be clarified that the drive block corresponding to the shaft is damaged, and the drive block needs to be replaced. If the axis is still not working, it is clarified that the cable or the motor has a faulty replacement cable or motor. The three axes cannot move. At this moment, check if the three-axis aviation plug is connected to the control box and the control box power is turned on. Whether the data cable is connected to the control box and the control card in the computer mainframe. If all of the above are normal, please contact the factory.
(3) The spindle of the computer carpenter engraving machine cannot operate normally. First look at the error code displayed on the LED display of the inverter (see the inverter error code item in the inverter). The following is an example of the YIXING inverter.
YIXING series inverter common faults and treatment (1.5 kW)
Fault code: DL output short circuit to see if the motor and cable are shorted
OL1OL2 load is too large, the motor is blocked, the blockage is eliminated, and the load is reduced.
LU undervoltage input voltage abnormally view input power
OH overheating load is too large, cooling fan damage, reduce load replacement fan (Note: When the inverter displays DL, the reset button is invalid, please power off and restart the inverter to eliminate the problem)
TALENT series inverter common faults and treatment (2.2 kW)
Fault code: EOCD output short circuit to see if the motor and cable are shorted
EOU input voltage is too high to view voltage
EOCN output loop phase-to-phase short circuit or short circuit to ground to view wiring and motor
Does the ELU have a large starting current load in the same power system?
TL external disturbance separates the control line from the strong power
Common problems and handling of spindle motors:
The motor is hot to see if the pump is working properly.
The motor is boring to see if the motor cable is short-circuited.
Motor noise abnormal motor is overloaded motor internal fault (please contact the manufacturer)
Motor rotation to see if the motor line is out of phase, the output UVW end will be interchangeably
CNC carpenter engraving machine maintenance and protection can not only better extend the service life of the equipment, but also useful to reduce the incidence of equipment problems, useful to improve the precision of engraving.
