    1. The processing of dislocation, or the wrong size

    1, check the transmission chain transmission gap size
    2, check the engraving path is correct or not; 
    3, check the gap size and the degree of fastening screw; 
    4, check the software parameter settings are correct or not; 
    5, check whether the grounding wire; 
    6, check whether the computer virus.

    2. To solve the common faults of carving machine

    1, the machine is not energized. Check whether the start button is connected and the button is normal; check the AC contactor is normal; check the emergency stop switch is normal; check the fuse is normal.
    2, fine spindle does not turn or reverse. Check the setting of the parameters of the frequency converter; whether the signal line of the inverter is connected; check whether the spindle motor is normal or not. 
    3, processing depth varies. The control card is loose or fault; stepping motor fault; spindle motor fault; frequency interference or data set error; Z motor drive line fault; fault or current subdivision and software settings are not consistent; electrostatic interference; computer virus or system. 
    4, over limit phenomenon. Check whether the engraving path exceeds the carving range; the soft limit of parameter setting in the software; 
    5, smashing knife phenomenon. Z axis motor power is not enough, coupling loose; Z shaft drive current is too small, or the signal line is wrong; check the Z axis motor line is plugged.

    3. Why carved machine back to the mechanical origin of workpiece after the origin are not the same

    The machine deviation occurs, every time back to the mechanical origin, the origin of the workpiece are not the same, make the products of partial overlap, can coordinate with corresponding tool tool in the past are not in the same position that was also serious when even to the tool, the emergence of this situation, in addition to the control system, the machine software, driver, motor and mechanical parts to outside, may lead to these problems are as follows.
    1, the origin of the switch contact is aging, direct replacement of a carved machine origin switch. 
    2, the origin switch is loose, check whether the loosening of screws fixed origin switch, the original switch installation sheet metal (iron) is loose and soft deformation. 
    3, If the sticky oil carved machine origin switch, excessive dust and sticky cutting debris with air gun dry after cleaning, please.

    4. The difference between the processing center, milling machine, carving machine

    Conceptually speaking:
    Machining center: CNC machine tools with a high degree of numerical control of the tool library and automatic tool changer. It can be used for milling, drilling, boring, reaming processing and tapping and other procedures, the main function is milling. 
    The machine spindle speed is very high, the torque is small, highlight the "carved" function, mainly for the processing of organic materials such as glass, plate; 
    Milling machine: can the sculpture, can also increase the milling, engraving and milling machine spindle and servo motor power based on engraving machine, bed capacity, while maintaining high speed spindle, which is high precision. 
    From the technical index data: 
    The maximum speed of the spindle (r/min): processing center can reach 12000rpm; milling machine engraving machine to 60000-100000rpm reached 30000rpm. 
    The spindle machining center spindle power: the maximum power, from a few kilowatts to tens of kilowatts have a smaller chance; engraving, generally in the thousands of watts or less; the minimum power carving machine. 
    Cutting capacity: processing center, especially suitable for heavy cutting, hair embryo processing; engraving and milling machine is suitable for processing fine carved machine is suitable for fine processing. 
    From the comparison of accuracy, the accuracy of the three machines 
    From the application object: 
    The machining center processing of various molds and parts machining, engraving and milling machine is mostly used for processing soft metal products, especially suitable for processing of copper, graphite; engraving machine is suitable for processing color plates, acrylic, glass and other materials with high hardness processing, suitable for high-end chip, metal polishing etc..
