Problems with CNC cutting machines, and how to deal with the failure of the starting point of the re

The problems of CNC cutting machines are mainly concentrated in the following aspects:

1. CNC system, this aspect is mainly a software program problem, of course, there will be some other hardware problems, such as axis card, IO control board, power supply, etc.

2. The electrical control part, mainly PLC programmable controller (some low-end equipment is not used) and some relays are prone to problems, of course, there may be some loose wires and other problems.

3. Longitudinal and transverse drive, if the accessories selected are better, it is generally not easy to have problems, but if it is some miscellaneous products or imitation products, it can not be guaranteed, of course, in some areas, if the external input power supply voltage is unstable, and there are no voltage stabilization measures, there will be some problems, I encountered once, 3 sets of Panasonic servo drives are all burned out, but for a time can not be checked, the appearance and function are good, but the driver is always zero, As long as the power is turned on, the machine tool will move at a slow speed, and it will fly together, and finally check and check that there is a problem with the drive, although the first one is suspected that the drive is broken, but it is good to take the drive to other beds, inexplicably.

4. Some equipment will be equipped with automatic height adjustment devices, such as flame capacitance height adjuster, plasma arc voltage height adjuster, etc., this kind of device is more likely to have problems on the equipment, especially the capacitor height adjuster, generally within half a year will always shout for help, arc voltage height adjuster is slightly better.

5. The automatic ignition device equipped with flame cutting, this device is actually a large lighter, which is also relatively prone to problems, and is rarely used for more than half a year.

There are others, but they are not particularly common, so I will not list them all.

The above is a personal opinion, for reference only, if you have other questions about CNC cutting, welcome to continue with me**: 013584368643, or email: cwf

What is the main problem?

In general, there may be a problem with the debugging of the program.

1. The blade is reversed. Solution: Three-phase power supply is exchanged between any two phases.

2. The rising speed of the blade is unstable. Solution: one. Check whether the air source reaches the rated local pressure, two. Check the oil level of the reservoir, three. Check the upper and lower linear bearings of the guide post of the cutter housing.

Whether there is a foreign body inside, four. Check the cylinder for damage.

3. Abnormal noise of the machine. Solution: Check whether the motor is out of phase.

4. The blade does not rise, and the casing does not rise after cutting, and the saw blade does not fall. Solution: Check the throttle valve under the oil storage drum.

Whether it is shut down or damaged.

DHG4011 CNC cutting machine returns to the starting point of the program to cause the cause and treatment: 1. Fault cause and analysis: CNC plasma, flame cutting machine processing efficiency is high, widely used in mass processing of complex shape, high dimensional accuracy requirements of parts.

In the production of the wheel, we often put the parts of the same thickness on a whole steel plate for processing (for example: the size of the steel plate, the number of parts is up to hundreds), so as to make full use of the steel plate air and fuel interval, save raw materials, and improve work efficiency. However, due to the large size of the steel plate and the many processed parts, it takes several working shifts to cut the complete steel plate, and the cutting machine has to stop working several times in the middle, which requires the cutting machine to have the function of automatically continuing to cut from the breaking point in the next work after the breaking point.

At present, the DHG4011 CNC cutting machine used in the factory is working normally, and the operator can successfully complete the cutting work by using the breakpoint continuation function of the cutting machine. The method is: when the operator wants to stop working in the middle of cutting, and wants to save the breakpoint of the cutting site, press the S key to stop when running to the idle section, and then press the enter key to exit the cutting operation, and the breakpoint data is remembered by the system at this time.

At this time, the operator should remember the coordinate values in the x, y direction, and then turn into the idle operation to move the cutting machine in the opposite direction, until the coordinate values in the x, y direction are the same as the above remembered coordinate values, plus and minus signs are different (this position is the starting point of the program, but also the origin of the steel plate) can be shut down. The next time you start the machine, enter the letter C at the corner of the steel plate to continue the cutting operation that was interrupted last time. Imported pump valve industrial washing machine can be known through the above operation methods:

In order for the operator to stop the work in the middle of the process, he must first control the cutting machine back to the beginning of the program (or the origin of the steel plate) before he can continue cutting the next time. Obviously, if the cutting machine suddenly fails during normal operation (e.g., power failure, servo system failure, control computer crash, etc.), because it does not have a power-off memory function, the operator cannot return it to the starting point of the program (or the origin of the steel plate).

In this case, our general practice is: after the cutting machine is repaired and returned to normal, the remaining steel plate is edged, and then the programmer re-programs a new program for cutting. In this way, because some parts at the breakpoint are not cut, it is unusable, resulting in the waste of raw materials, increasing the production cost, and Tongjin also brings duplication of work to the programmer, resulting in the reduction of production efficiency.

Summary. Qinqin is happy to answer for you: the cutting machine is always bad cutting disc center is the cutting feed is too large, the cutting disc bears the torque more than the rated value too much, when cutting PVC pipes, the pipe must be fixed firmly, there can be no rotation, when cutting, control the feed, can avoid the phenomenon of damage to the cutting blade.

When cutting, the tube rotates, which is equivalent to a sudden increase in the cutting feed, exceeding the torque that the cutting disc can bear, causing damage to the cutting blade. I hope my answer helps you <> in person

The expansion that you have given you is: precautions for the use of cutting machines, as follows: 1

When working on the cutting machine, it is necessary to concentrate and be clear-headed, and operate the power tools in compliance with regulations. 2.It is strictly forbidden to pull the wires privately to ensure that the power lines are safe and reliable, and the power lines should be placed in compliance.

Before using the cutting machine, it is necessary to carefully check the equipment to ensure that every part of Bisui is in good condition. 3.Work clothes should fit well, not too loose and tight, do not wear jewelry to keep long hair, and it is strictly forbidden to wear gloves and cuffs without buttoning to operate.

Summary. Hello dear <>

The reasons why the cutter is always bad in the center of the cutting disc are as follows:1The cutting blade is worn unevenly:

After a long period of use, the cutting disc may wear unevenly, causing the center of the cutting disc to shift. It is advisable to replace the cutting disc regularly. 2.

Incorrect disc mounting: If the disc is not installed correctly, it can also cause the centre of the disc to shift. It is recommended to carefully check the cutting disc installation instructions to ensure that the installation is correct.

3.Cutting machine structure problems: If the structure design of the cutting machine is not reasonable or the manufacturing quality is not up to standard, it may also lead to the center of the cutting blade offset.

It is recommended to contact the cutting machine manufacturer or after-sales service center for technical support and assistance. 4.Operational Issues:

Improper handling, such as excessive or uneven force during cutting, can also cause the center of the cutting disc to shift. It is recommended to carry out the necessary operation training to ensure the correct operation method.

The cutter is always bad in the center of the cutting disc.

Hello dear [Xianbo Accompany Flowers]: The cutting machine is always broken in the center of the cutting disc for the following reasons: 1

Uneven wear of the cutting disc: After a long period of use, the cutting disc may wear unevenly, resulting in the center of the cutting disc. It is advisable to replace the cutting disc regularly.

2.Incorrect disc mounting: If the disc is not installed correctly, it can also cause the centre of the disc to shift.

Lu Yinxian recommends carefully checking the installation instructions of the cutting blade and taking early shots to ensure that the installation is correct. 3.Cutting machine structure problems:

If the structure of the cutting machine is not properly designed or the manufacturing quality is not up to standard, it may also cause the center of the cutting disc to shift. It is recommended to contact the cutting machine manufacturer or after-sales service center for technical support and assistance. 4.

Handling problems: Improper handling, such as excessive or uneven force during the cutting process, can also cause the center of the cutting disc to shift. It is recommended to carry out the necessary operation training to ensure the correct operation method.

If the cutting machine is always bad in the center of the cutting disc, a detailed inspection and analysis is required to find out the specific cause and take corresponding measures to solve the problem. 1. Check whether there is a problem with the grinder. The simple solution is to change the grinding wheels, and if each of them has such a problem, then the grinder needs to be repaired.

2. Check whether there is any error in the operation of the ulnar limb. It should be operated in strict accordance with the operation manual, and the knife should not be fed too fast when cutting the material, nor can it cut multiple materials at one time. 3. Check whether there is a problem with the quality of the grinding wheel.

The grinding wheel with poor quality has too little binder, and the centrifugal force generated at high speed during work is easy to break the grinding wheel. It is advisable to use high-quality cutting discs for conversion. I wish you a happy life!

I hope mine is helpful to you.

I wish you a happy life! Hope mine is helpful to you ha.

The first step is to check whether the mechanical part of the walking track is off the track or obstruction when the servo drive is powered off, and also check whether the screws of the bearing part between the motor and the reducer are loose (this operation only needs to remove the four screws around the motor and the reducer, and then lift the motor up by hand, if it is directly raised, the screw is loose in the place where the motor shaft and the reducer clamp shaft are clamped, and the screw can be tightened in the position. It is recommended to perform manual moving of the servo drive before tightening the screws, and at this time to see whether the air motor is rented and stopped). The second step is to perform manual moving on the CNC system to check whether the reducer gear under the motor or the motor that has been removed in the first step is running?

If it is not running, check whether the servo drive has the corresponding display value change when performing manual moving (depending on the servo drive brand and model to determine the display change content). Step 3 At this time, if the servo drive shows the value change, you need to check whether there is a problem with the motor power line encoder line, if the servo drive does not display the value, you need to check the connection between the CNC system and the driver and the problem of the system drive port, this step needs to be executed by professional technical engineers.
