Engraving machine common failures and solutions

Everything can't be long preserved intact, judge engraving machine some common faults in the daily production and understanding simple engraving machine fault solution is very necessary, mechanical engraving machine below and share with you common failures and solutions, basically has the following kinds: 15 a, spindle automatic roll over or stop not 1, control card failure; 2, frequency converter fault 2, open the software, computer prompts 'open card failed, please check the card' hint 1, check the card driver have installed, or change my card by a PCI slot; 2, the two root data cables to installation, check if there is any breakage phenomenon; 3, the card has a problem, replace the board. Three, open the software prompts: three axis alarm, initialization error 1 4, check the computer have two wires connected with the machine; 2, check whether control box only a fuse of the adapter plate burning, change the fuse; 3, check whether the 85 v power supply when the normal power supply four, sculpture, dislocation or wrong size 1, check the path of the carving software correctly or not; 2, check the clearance size of screw and the screw securing the polished rod have loose; 3, check software parameters set of five, the X axis to walk a certain period of Z axis don't lift the knife, press the up going but go down 1, check whether the Z axis motor run normally, the size of the power and the drive current or their own fault; 2, check whether the Z axis motor line have poor contact or discontinuity in the six, spindle motor does not turn or reverse 1, check the inverter parameters Settings; 2, frequency converter signal whether pick up against. Found a breaking knife, 1, Z axis motor power is not enough, loose coupling. 2, Z axis drive current is too small, or the wrong line. Eight, open software boot, axis close, 1 drive problems or computer output signal poor contact; 2, motor line contact undesirable. Nine, sculpture limit phenomenon appeared in the process of 1, check whether the carving path is range of sculpture; 2, the parameter Settings in the software of the soft limit. Ten, machine no electricity when the phone is switched on. 1, check whether the start button line is connected and the button is burn out; 2, check whether the ac contactor is short circuit or burn out. Eleven, button when motion axis in one direction only go 1, check that the light lotus root line is working correctly and whether line contact good; 2, check the motor line if there is a virtual welding. 12, send software can't normal open, graven things appear deformity. 1, to install the new system and software; 2, check the X, Y axis screw and screw loose; 3, carving knife has a problem. 13, engraving machine working process of the spindle motor sudden halt or slow 1, the working voltage instability or super load, add a voltage stabilizer; 2, check whether the median line is connected and the thread if there were any desoldering. 14, carving machine, set forward, sometimes to the right when the origin offset distance variable 1, limit switch failure, in the process of system back to the origin of the limit switch is closed and bounce off. Change the limit switch; 2, drive wire is loose. Managed to get it fixed tightly. 15, carving machine start reset for the X, Y, Z axis floating 1, limit switch (bad Limit switch is closed) , change; 2, drive line bad ( With 15 X 14 needle short circuit, short-circuit, and 15 Y 13 needle Z axis with 15 31 needle short circuit) , the drive line or short circuit disposition open; Change 3 bad, drive plate, driven plate can.
