A good way to troubleshoot and deal with the failure of the four-process CNC cutting machine

At present, the four-process CNC cutting machine occupies a large proportion in the market, especially for newly-built panel furniture factories. Many customers regard the four-process cutting machine as the preferred model. In order to create revenue, some customers have bought the machine and operated it with shafts, and neglected the maintenance of the machine, resulting in a lot of problems. Below we will list several common machine failures and treatment methods.

Analysis of common failures of CNC cutting machine spindle:

1. The spindle motor of the CNC cutting machine is hot:

Solution: first check whether the water pump is working, and whether the circulating water is low in the liquid level.

2. I feel that the motor has no strength and can't rotate:

Solution: Check the circuit to check whether the motor line is lacking phase, or whether the cable line is short-circuited.

3. The motor makes a strange sound:

Solution: Check whether the motor is overloaded; there may be a fault in the motor, and it should be repaired or replaced in time.

Fourth, the motor reverses:

Solution: directly check whether the motor line is lack of phase or change the output UVW end, which is the line connecting the inverter to the spindle motor.

5. Spindle reversal phenomenon of CNC cutting machine:

During the working process of the CNC cutting machine, the spindle of the engraving machine is reversed. It is because the wire connecting the inverter to the spindle is reversed. You can change the two wires to rotate forward.

When the spindle is reversed, if the MDF is engraved, the knife will be broken, and the knife may break after it is installed. Sometimes even if it is not broken, it will be burnt red. Therefore, if such an abnormal phenomenon occurs, stop the machine and check the spindle.

When using a CNC cutting machine for production and processing, how to avoid errors in engraving production is a problem that many customers are concerned about, because often because the engraving path is set incorrectly or the operation is incorrect, engraving errors are prone to occur, and the result of errors is a waste of plates. This is a big waste, because many customers use very expensive plates. If a little error occurs, the plates are required. This is a big waste, because many customers use plates that are very expensive and a little error occurs. The whole board will be wasted. Therefore, how to avoid the engraving error of the CNC cutting machine is a common problem that everyone faces. Here, the engraving machine manufacturer tells you a trick to use the control system to avoid the engraving error of the CNC cutting machine.

Failure analysis of CNC cutting machine:

During the engraving process, the CNC cutting machine suddenly appears 1. The limit switch is triggered; 2. The working range is exceeded.

Reasons: 1. The limit switch is triggered mechanically and interfered with; 2. The machine origin is not returned to before the operation and processing, and the processing data parameters exceed the processing size of the mechanical table.

Solution 1. Check the limit switch sensing point to see if there is metal contact. If the metal contact is cleaned up, the problem can be solved; if there is no metal contact, check the limit switch wiring, remove the short circuit problem, and the fault can be eliminated . If the above reasons do not exist, you should check the line interference problem, wrap the limit switch line with a magnetic ring, and do the degaussing part to solve the problem.

2. The machine will automatically stop working after the soft limit alarm occurs. At this time, please select the "Back to mechanical origin" item under the "Operation" menu in the operation control system to clear the three axes at the same time, and then continue to engrave at a fixed point. The problem can be solved.
