What are the reasons for the loss of control of the Z axis of the CNC engraving machine? How to solv

When the engraving machine does not work normally, it may be that there is a problem with its internal components or other reasons, and the following is a general introduction to the problems that often occur. One of the three axes cannot be moved. At this point, check whether the drive block corresponding to the corresponding shaft is damaged.

The inspection method can be replaced by the substitution method: the aviation plug corresponding to the immovable shaft is unplugged and inserted into the drive corresponding to the other movable shaft. If the immovable shaft moves normally after the exchange, it can mean that the drive block corresponding to the shaft has been damaged and needs to be replaced; If the shaft still doesn't work, it means that the cable or motor is faulty and needs to be replaced.

None of the three axes can be moved. At this time, check whether the three-axis aviation plug has been connected to the control box, whether the power supply of the control box has been turned on, and whether the data cable is connected to the control box and the central control of the computer host

Friends who have operated the engraving machine know that the engraving machine has three main spindles are X, Y, and Z axes, so any of them will affect the overall normal operation. In the previous section, the causes of X-axis and Y-axis failures and corresponding emergency measures were introduced.

Reason (1): Human error, including exceeding the limit of the physical range of the z-axis by 150mm;

Solution: Operate in strict accordance with the operation specifications.

Cause (2): Control card failure;

Solution: Check whether the control card is plugged in tightly, and replace it with a new card if it is not loose.

Reason (3): poor contact of Z-axis motor line;

Solution: Use a pen to test the energizing condition of the motor line and repair the problematic parts;

Reason (4): inverter or electrostatic interference;

Solution: If it is static interference, you can buy an ionic wind copper rod to release static electricity before each start-up;

If it is inverter interference, the fundamental frequency of the inverter can be changed first, which can be set in the inverter parameters. The analysis may be that the fundamental frequency of the inverter is exactly the same as the sampling frequency of the pt100 temperature detector, so the fundamental frequency of the inverter should be skipped over this frequency band and give it a try. No, according to the second floor, the second floor is also reasonable, the inverter's shielding and grounding disposal is not good, and the interference is greater.

Reason (5) The computer system of the engraving machine is poisoned, resulting in the error of the predetermined path;

Solution: Purchase regular anti-virus software to prevent viruses on a regular basis to ensure the normal operation of the system.

Causes and solutions:

1. It may be that the connection of the driver is off or the travel companion is in poor contact.

Solution: Check or replace the drive cable.

2. There is a problem with the motor connection of the engraving machine.

Solution: Check or replug the data connection.

3. There is a problem with the engraving machine system.

Solution: Check the system card and set the installation again.

Summary. Causes and solutions:

1. The connection of the driver is falling off or the contact is poor.

Solution: Check or replace the drive cable.

2. There is a problem with the motor connection of the engraving machine.

Solution: Check or replug the data connection.

3. There is a problem with the engraving machine system.

Solution: Check the system card and set the installation again.

What is the reason why the z-axis of the engraving machine cannot move up and down?

Causes and solutions: 1. The connection of the driver is falling off or the contact is poor. Workaround:

Check or replace the drive's wiring. 2. The solution to the problem of the motor connection of the engraving machine: check or re-insert the data connection.

3. The solution to the problem of the engraving machine system: check the system card and re-set the installation.

Hope it helps.

What is the problem that the failure of the Keye carving machine shows that the z-axis following error is exceeded? Hello dear, the position deviation is too large, which is generally caused by the loss of steps of the servo, and the parameters of each ring of the servo should be optimized. Or it should be a location loop fault.

Including motor encoder, grating ruler, drive system, servo measuring board. Focus on these aspects. Or maybe the x-axis doesn't work anymore.

This depends on whether there is an alarm number on the driver panel, if there is an alarm number, it is a driver failure, if it is normal, it is to see if the drive motor or lead screw is faulty, if it is normal. The z-axis following error is too large, which is the reason for the torque to be too fast. I hope I can help you if my answer is helpful to you, please also give a thumbs up (in the lower left corner of the evaluation of the birds), looking forward to your like, your late efforts are very important to me, and your support is also the driving force for my progress.

Finally, I wish you good health and a good mood!

The size of the Z-axis of the CNC lathe is unstable, and the problem of automatic offset of the coordinate point can be solved for the following reasons:

Insufficient stiffness of the machine tool: The insufficient stiffness of the machine tool will lead to the deformation of the Z-axis in machining, which will lead to problems such as reduced machining accuracy and coordinate offset. It is necessary to check whether the structure and parts of the machine tool are normal, such as slide rails, screw rods, etc., whether they are worn or damaged.

Z-axis screw or guide rail damage: If the Z-axis screw or guide rail of the CNC lathe has problems such as wear, cracks or deformation, it will also cause the coordinate wisdom point to automatically shift. These parts need to be inspected and replaced.

Faulty servo motor or encoder: A faulty Z-axis servo motor or encoder on a CNC lathe can also cause the coordinate point to automatically shift. The problem can be solved by inspecting parts such as motor drivers and coding spring songers, and debugging and repairing.

Improper setting of cutting parameters: If the cutting parameters are not set properly, such as too fast feed speed, too large feed depth, etc., it will also lead to unstable Z-axis dimensions and automatic offset of coordinate points. Cutting data needs to be adjusted and optimized.

Environmental factors: Factors such as ambient temperature, humidity and other factors may also affect the operation of the CNC lathe, resulting in unstable z-axis dimensions. The environment around the machine needs to be kept dry and ventilated, and adjusted according to the actual situation.

To sum up, the problem of unstable z-axis size and automatic offset of coordinate points of CNC lathes can be caused by a variety of reasons. It needs to be inspected and analyzed on a case-by-case basis, to identify problems and to fix and adjust accordingly.

There are common queries, blanking calculations, various G**, macro programs, mechanical design and drawing, CNC system operation instructions, programming examples, 2D, 3D drawings, and tutorials. I believe it can help you solve your problems about machinery and numerical control.
