Woodworking engraving machine adsorption platform insufficient suction solution

In the use of woodworking engraving machines, there may be a phenomenon that the suction table has no suction and cannot absorb the plate. What is the reason for this? How should it be solved? Today, we will introduce you to the solution that the woodworking machine table does not absorb:
1. Is the motor line voltage normal?
2. Whether the water circulation air pump adds less water, whether the motor is stuck or not, and the rotating shaft of the motor fan protection net is removed;
3. The filter in the vacuum pump is blocked and cleaned;
4. The surface of the counter or pipe is trimmed by air leakage;
5, positive and negative exchange motor, any two lines change the direction of the motor.
The woodworking engraving machine uses vacuum adsorption to fix the plate, which not only can be firmly fixed, but also does not move and engrave the misalignment, etc., and the plate is fixed relative to the splint, which can save the plate and engrave to the edge of the plate, saving time and effort.

The difference between the cutting machine and the engraving machine

The difference between CNC cutting machine and engraving machine;
  The engraving machine and the cutting machine are substantially different. Although the appearance looks similar, the bed structure and production process of the two equipments are completely different. The materializer is not comparable in terms of configuration or process accuracy to the engraving machine. The engraving machine mainly engraves fine patterns with various patterns such as flower shapes and gate shapes. The unloader is mainly used to rough a sheet into different sizes. Of course, the engraving machine can also be unloaded, but it is slower than the cutting machine. All duties and responsibilities must be used.

  First of all, in terms of price, the traditional engraving machine, multi-process engraving machine is about 2-3 million yuan lower than the corresponding cutting machine equipment, and this price is only a rough basis, the price of the cutting machine market is different due to the configuration price. It is also different, and the operation process is different.
  The price of the CNC cutting machine is very important. Because the overall configuration is higher than that of the engraving machine, the bed component of the cutting machine is one-half or even double the weight of the engraving machine. Moreover, most of the cutting machines choose 1.5 die racks, 25 or 30 rails, which is higher than the engraving machine. The brand selection is more cautious than the engraving machine. All of this is to meet the performance of the cutting machine. The cutting machine is a high-precision, heavy-duty processing for sheet metal cutting. The uniform processing speed of the CNC cutting machine can reach 15m/min, and the cut plate requires no smashing, sawtooth, wave pattern and so on. Heavy-duty bed, high-quality rail racks ensure that the machine will not deform during long periods of high-speed operation. The engraving machine is slow in speed, low in precision when the sheet is opened, and the heavy load operation for a long time will greatly affect the service life of the equipment.

  In addition, the CNC cutting machine should distinguish between hybrid servo, domestic servo or export servo when selecting the motor type. It is different from the step servo of the ordinary carving machine. It is important to meet the high-speed and high-precision machining requirements of the cutting machine and improve the processing efficiency. .

The application and development of small laser engraving machine in the LED industry?

       Small laser engraving machine cutting is a kind of laser emitted by a high-energy laser. Focusing through the lens, it achieves a high laser power density at the focus. The high-power density laser illuminates the workpiece point, which will generate local high temperature and instantaneous vaporization of the workpiece material. , melting, and controlling the platform to drive the movement of the workpiece, the formation of a new cutting non-contact mode.

Advertising word laser cutting machine lens cleaning?

1. First, the air ball is used to blow off the floating surface of the component surface, especially the lens with tiny particles and flocs on the surface. This step is necessary. But don't use compressed air on the production line because it contains oil and water droplets, which will deepen the pollution of the lens.

2. In the second step, the lens is slightly cleaned with acetone. This grade of acetone is almost anhydrous, which reduces the likelihood of lens contamination. The acetone on the cotton ball must be cleaned under illumination and circularly moved. Once the cotton swab is dirty, it must be replaced. Cleaning should be done at one time to avoid creating ribs. (If the lens has two coated surfaces, such as lenses, each side needs to be cleaned in this way. The first side needs to be placed on a clean lens paper for protection.)

3. If acetone does not remove all the dirt, then use acid vinegar to clean. Sour vinegar cleaning uses the dissolution of dirt to achieve the removal of dirt, but does not cause damage to the optical lens. This acid vinegar can be experimental grade (diluted to 50% strength), or white vinegar of 6% acetic acid for household use. The cleaning procedure is the same as for acetone cleaning, then acetone is used to remove the vinegar and dry the lens. At this time, the cotton balls are frequently changed to completely absorb the acid and hydrate.

Advertising word laser cutting machine lens cleaning precautions? (Note: Only use a pure cotton swab with a label. Only use high quality medical cotton balls that have been selected and do not contain any abrasives.) Of course, certain contaminants and lens damage cannot be removed by cleaning, especially because of The film is burnt out caused by metal splashes and dirt. The only way to restore good performance is to replace the lens. Proper installation method During the installation process, if the method is not correct, the lens will be contaminated. Therefore, the previous operating procedures are to be followed. If a large number of lenses need to be installed and removed, it is necessary to design a fixture to accomplish the task. A dedicated fixture reduces the number of contact with the lens, reducing the risk of lens contamination or damage. In addition, if the lens is not installed correctly, the laser system will not work properly or even be damaged. All CO2 laser lenses should be mounted in one direction. Therefore, the user should confirm the correct direction of the lens. The mirror is the third common lens and its installation is also critical. Of course, it is easy to distinguish the reflective surface for the mirror. It is obvious that one of the coating faces the laser. In general, the manufacturer will mark the edges to help identify the surface. Generally this mark is an arrow with the arrow facing one side. Every lens manufacturer has a system for marking lenses. In general, for mirrors and output mirrors, the arrows face the high side. For lenses, the arrows face the concave or flat surface. Sometimes the lens label will remind you of the meaning of the mark. When the lens is properly cleaned and operated, its service life and performance will undoubtedly improve significantly, which is one of the important ways to improve the life and stability of the laser cutting machine. Taking some precautions and maintenance measures will ensure that the laser cutter will work longer and be more stable.

How to use the tips of the advertising engraving machine?

First, since the advertising engraving machine is often equipped with multifunctional pliers or chucks, and they are made of iron, it is easy to damage the engraved objects or cause them to slip during the engraving process. Then use some rubber caps or rubber. It is helpful to use the tube for the fixation of the engraved object.

Secondly, when engraving the plastic pattern on the advertising engraving machine, the transfer tape can be attached to the back side of the engraved object, and the tape-coated side is sprayed with the liquid spray glue, and then attached to a surface which can be discarded. This avoids the use of double-sided tape, leaving a surface that is difficult to clean. Because the transfer tape is easy to peel and clean. Using a special engraved tape, the side of the tape is more viscous than the other side, so the plate can be moved at will. .

Third, for those irregularly shaped engraved objects, the surface seems to have been fixed very tightly, and when it is under pressure, it will also sway back and forth. At this time, you can try to put some scrap under the object to increase friction. The other is to keep the package that comes with the item. Although the object is irregularly shaped, the package itself may be very regular and easy to be fixed, plus a small strip of irregularly shaped objects. It is easy to fix. Or try to fix its regular parts and discard its irregular parts.

Fourth, if the downforce to be engraved is large, consider whether you must use a cone-shaped nose. If the pressure of the diamond engraving machine in the engraving process is too large, the pressure on the side of the tool will cause The movement of the engraving. If an incorrect diamond knife is used, it will also cause the same problem. A 90 or 100 degree diamond knife will penetrate the material and move the material during the engraving process.

How to use the advertising engraving machine?

1. In the actual processing, the relationship between machining effect and machining efficiency should be fully considered, and the coarse knife, fine knife and three-dimensional engraving can be flexibly applied. Large-area graphic area engraving uses large tools for processing, and small-area graphic areas or The effect of the small tool should be used for fine machining, and the setting of the overlap rate of the tool is also important.

2. Select the processing method according to the processing result requirements-----two-dimensional engraving, three-dimensional engraving or cutting. If pattern engraving is performed, two-dimensional or three-dimensional engraving is selected, and the generated processing path is the engraving path. If you are cutting and machining the wall surface of the sand table model, select "Cutting Word" and the generated path is the cutting path.

3. According to the requirements of processing effect, the path generation method is selected. The two-dimensional path is suitable for plane engraving. The processing effect does not have a strong three-dimensional effect, and the processing fineness is inversely proportional to the processing depth. The three-dimensional path has a "clear angle" engraving action, the processing effect has a strong three-dimensional effect, the processing pattern is fine, the processing fineness is directly related to the fineness of the pattern and the accuracy of the tool parameters, and the processing depth only affects the three-dimensional and does not affect the fineness of the processing. The degree, the greater the processing depth, the stronger the stereoscopic effect.

4. According to the fineness of processing and the texture of the material, choose the engraving processing path form----horizontal milling bottom, vertical milling bottom, forward 45 degree milling bottom, reverse 45 degree milling bottom. These engraving paths produce high processing precision. The processing surface is smooth. The circular path has a fast processing speed and high efficiency, but the processing effect is inferior to others.

5. Engraving tool selection, pay attention to the influence of cutting edge angle and blade width on machining accuracy and progress. If the cutting edge angle and blade width are large, the machining speed is fast, but the machining pattern is not fine, the cutting edge angle and blade width are Small processing speed is slow, but the graphics are fine and the durability of the tool is relatively poor.

How to use the advertising engraving machine without damaging the milling cutter?

1. Whether the power supply provided by the advertising engraving machine is stable, and the unstable power supply will cause the advertising engraving machine to break the knife.

2. Whether the engraving machining allowance is reasonable, whether there is a stepped margin, so that there will be a change in the cutting force causing vibration during the machining, resulting in the broken knife, so it is necessary to increase the semi-finishing. The other is whether the amount of knife is too large.

3. Check whether the priority mode of the advertising engraving machine is correct. It directly affects the starting speed of the machine. The higher the starting speed, the more likely it is to generate vibration, which will easily lead to broken tools.

4. Whether the materials processed by the advertising engraving machine have impurities and the hardness of the material is too large.

5. Whether there is dust on the engraving machine tool and the chuck, whether the upper knife is too strong. The chuck and nut are not intact. It is very important that the amount of tool sticking is large. It is often a problem here and it is not taken seriously.

6. Tool problem: It is mainly related to the hardness, strength, sharpness and length of the special tool, and the smoothness of the tool rake face. This requires the user to select the correct tool for machining before machining.

7. Whether the advertising engraving machine is flattened at the bottom of the machine, if it is not leveled, it may cause a broken knife. Whether the spindle motor speed is too low, the spindle motor speed is too low, the amount of knife per tooth per revolution becomes larger, so the cutting force becomes larger, which will cause the knife to be broken. Generally speaking, the spindle speed we use is still high. Some are good.

Advertising engraving machine water will not cycle what is going on?

1. The pump power is too small to perform the water circulation activity from low to high.

2, the water is not often replaced, there are impurities in the water, blocking the water inlet of the motor, resulting in reduced pressure.

3. It is because a large amount of water rust accumulates in the spindle motor during long-term work, which hinders the normal circulation of water. This is also the most common cause. The solution is to change the water frequently.

What should I do if the advertising engraving machine does not circulate?

1. Check that the pump power is too small and replace it if the power is too small;

2. Change the water frequently.

Advertising engraving machine computer maintenance?

1. Clean the dust of the chassis regularly, pay attention to the heat dissipation of the chassis, and be careful that the industrial control card is faulty due to excessive dust.

2. Regularly defragment the disk and optimize the computer system.

3, regularly check and kill the virus, but pay attention to work can not open the anti-virus program to prevent interference work.

The use of advertising engraving machine cooling water?

1. Cooling water is a necessary condition for the normal operation of the spindle motor. If the cooling water is too dirty, it will cause serious damage to the motor. Therefore, the cooling water must be cleaned to ensure the normal operation of the pump.

2, pay attention to the water level, must not make the water-cooled spindle motor water shortage, so that the motor heat can not be exported in time.

3, pay attention to the ambient temperature, be careful because the water temperature is too cold and cause the water tank and water pipe to freeze.

4. Conditional antifreeze can be used for cooling.

What is the difference between an advertising engraving machine and a woodworking engraving machine?

1. The difference between advertising engraving machine and woodworking engraving machine: processing materials are different. The advertising engraving machine mainly processes advertising decorative plates, including acrylic, PVC, KT boards, etc. Woodworking engraving machines generally process wood.

2. The difference between the advertising engraving machine and the woodworking engraving machine is two: the vacuuming device is different.

Engraving machine common fault analysis

The furniture used by people is usually made of sheet metal. Although the surface of the sheet is smooth, it is not beautiful enough, so the manufacturer engraves a three-dimensional pattern on the sheet to enhance the aesthetic appearance of the sheet. Nowadays, it is very common for people to use the machine to engrave the plate. When the program is sent to the control card, the machine can complete the engraving work according to the program, which is very convenient.

The engraving machine is a commonly used machine for engraving plates. It is possible that the machine may have problems. The common problems of the engraving machine are as follows:

1. The spindle and the table are not perpendicular; if the spindle and the table are not perpendicular, the problem is that the pattern is engraved and the depth is different, so the correction should be made when the spindle and the table are not perpendicular. The reason for this is the problem with the tool or the problem with the control card, which can be adjusted after the cause is identified.

2. The spindle drive sound of the engraving machine is not normal. When this happens, consider whether there is a problem with the Z-axis drive or the Z-axis screw. The solution is to determine if the spindle is rotating and to check the settings of the drive. An abnormal sound will appear when the spindle is stopped or the inverter is set incorrectly.

3. The engraving machine moves in the opposite direction to the origin of the machine. The cause of this phenomenon is likely to be due to damage to the spindle itself or problems with the bearing. The solution is to modify the wiring direction of the inverter or adjust the direction of the motor.

4. The engraving machine cannot return to the original point normally. When this happens, you should consider the cause of the control card failure, limit switch failure, drive failure and motor failure, and then do a check.

What is the performance of the engraving machine?

    Engraving machine is a kind of modern machinery and equipment widely used in advertising, woodworking decoration, stone, metal carving and other industries, bringing great convenience to the entrepreneurs' development. What factors determine the performance of the engraving machine?
    It is mainly determined by the engraving speed, engraving intensity and spot size:
    1. Engraving intensity refers to the intensity of the laser that strikes the surface of the material. For a particular engraving speed, the greater the intensity, the greater the depth of the cut or engraving. You can adjust the intensity with the engraver panel or with your computer's print driver. In the range of 1% to 100%, the adjustment range is 1%. The greater the intensity, the greater the speed. The depth of the cut is also deeper.
    Second, the size of the beam of the engraving machine can be adjusted by using lenses with different focal lengths. Small spot lenses are used for high resolution engraving. Large spot lenses are used for lower resolution engraving, but for vector cutting, it is the best choice. The standard configuration for the new device is a 2.0 inch lens. Its spot size is in the middle and is suitable for all kinds of occasions.
    Third, the engraving speed refers to the speed at which the laser head moves, usually expressed by IPS (inches per second), and high speed brings high production efficiency. Speed ​​is also used to control the depth of the cut. For a given laser intensity, the slower the speed, the greater the depth of the cut or engraving. You can adjust the speed with the engraver panel or with your computer's print driver. In the range of 1% to 100%, the adjustment range is 1%.

Woodworking engraving machine lost solution

Only by knowing and mastering the relevant performance of the wood engraving machine in detail can we solve the problems quickly in the process of use, so as to improve the processing efficiency.

1. First look at whether the machining speed inside the machining parameters exceeds the limit speed of the machine, please change to the appropriate engraving speed.
2, secondly reinstall the woodworking engraving machine control system (the handle user will format the handle), computer virus or U disk virus may damage the control system program resulting in lost.
3. Check if there is any interference source near the woodworking engraving machine, such as high voltage line, transformer equipment and other interference equipment.
4. On the woodworking engraving machine, the coupling may be loose, and the loose coupling will be tightened in time.
5, the power supply instability can also cause this problem, replace the power source or increase the voltage regulator.

Stone engraving machine engraving necessary daily maintenance and maintenance

The stone engraving machine is a precision numerical control equipment, and the necessary daily maintenance and maintenance is essential to the service life and accuracy of the machine. Please perform the maintenance and maintenance as described below.
1. The continuous running time is less than 10 hours per day to ensure the cleaning of the cooling water and the normal operation of the pump. The water spindle motor must not be dehydrated, and the cooling water should be replaced regularly to prevent the water temperature from being too high. In winter, if the working environment temperature is too low, the water in the water tank can be replaced with antifreeze.
Second, each time the machine is used, it is necessary to pay attention to cleaning. It is necessary to clean the dust on the platform and the transmission system, and regularly and weekly (weekly) lubricate the transmission system (X, Y, Z three axes). (Note: X, Y, Z three-axis polished rods are maintained with oil; high-speed butter is added to the screw; in winter, if the working environment temperature is too low, the screw, polished rod (square rail or circular guide) should be cleaned with gasoline first. Then add the oil, otherwise it will cause the resistance of the machine transmission part to be too large and cause the machine to be misaligned.)
Third, the maintenance inspection of the electrical appliance is, must cut off the power supply, until the monitor has no display and the main circuit power indicator is off, before proceeding.
