How long can a woodworking engraving machine last?

      Nowadays, all kinds of industries have realized the application of mechanical processing and production. How long can the engraving machine purchased by customers be used for the processing industry? I believe this is a concern of every customer. Of course, the processing life is different. Not the same.

      Woodworking engraving machine life is generally designed for about ten years, which is in an ideal state.
   
     Woodworking engraving machine should pay attention to maintenance and maintenance in use. If the normal working system is 8 hours a day, it is generally no problem to use 5-6 years.
   
     However, the life of the woodworking engraving machine is based on the customer's usage and cannot be determined. If your business is very good and the processing volume is large, then the main shaft is the most important wear bearing, this time is between one year and several years. Like the mechanical structure, the only thing that is bad is the slider, but it is no problem for a few years, and it is easy to replace. On the circuit side, the aging of the wire and the aging of some electronic components are damaged.
Of course, the configuration is also a critical issue, and the high configuration machine will also extend the life of the engraving machine. Generally speaking, the engraving machine is equipped with an imported spindle, imported drive and Taiwan guide rail, bearing gravity, and three-axis dustproof. If the dust is relatively large, it is better to have a dust cover for the equipment to be purchased.

Laser engraving machine

The laser engraving machine can perform cutting, engraving, drawing, and the like without touching the workpiece, and can fully utilize the processing material without wasting. The processing efficiency is also faster than the ordinary engraving machine and the machining accuracy is accurate. The operation method is also very simple. As long as the size of the workpiece is input into the computer, the system will automatically generate the machining path. The laser engraving machine will engrave the material into the finished product you need. No need for tools, no mold, only laser to complete non-contact. Processing, simple and fast.
The laser engraver is a laser beam that focuses on high power density. By using a laser beam to illuminate the surface of the workpiece, the high temperature of the laser beam instantaneously causes the workpiece to reach the melting point, while the air tube coaxial with the beam rapidly blows the workpiece. The formation of the workpiece as the movement of the beam position has involved a good dimensional pattern. Laser engraving processing replaces traditional mechanical tools and tool magazines with light beams that can generate instantaneous high temperatures, saving production costs. Laser engraving machine has high precision, fast speed, and is not limited by engraving patterns. Low cost features gradually improve or replace traditional metal engraving process equipment. The mechanical part of the laser head has no contact with the workpiece, and it will not scratch the working surface during the processing operation; the laser engraving speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the effect after engraving is small, the material is not deformed; the incision is smooth Neat, no need to cut the burr again; laser engraving machine has high processing precision and will not damage the appearance of the processed material; CNC private system control, input workpiece size and it will automatically form the plan of the workpiece processing, which can greatly save the design graphics time.
When the traditional engraving machine cuts various materials, the cost is too high, the manufacturing cycle is long, the size is not inconvenient, the delivery time is affected, and some sharp corners encountered during the processing cannot be satisfactorily processed. When the engraving machine processes the fabric, there is no way to solve the roughening of the incision, which brings a lot of inconvenience to the operation of the subsequent process, which greatly affects the quality of the follow-up work and makes the engraving machine's market competitiveness in this industry decline.
The original force laser engraving machine is cheap, the processing speed is fast, and it does not affect the mechanical stress of the workpiece. Therefore, the accuracy of the engraving and processing and the engraving speed are very good. The smooth running incision is exquisite and bright, and it also has the characteristics of safe operation. No downtime processing for 24 hours.

Similarities and differences between CNC engraving and milling machine and small CNC engraving machine

       CNCengravingandmillingmachine It is a kind of CNC machine tool. It is a CNC machine tool that corresponds to a traditional engraving machine. Most of them think that the engraving and milling machine is a CNC milling machine that uses small tools, high power and high speed spindle motors. The advantage of the engraving machine is in the engraving. If the hardness of the processing material is relatively large, it will not work. The appearance of the engraving and milling machine can be said to fill the gap between the two. The engraving and milling machine can be engraved or milled. It is an efficient and high-precision CNC machine tool. The Sylph engraving and milling machine is an outstanding masterpiece of CNC engraving and milling machine.

Engraving machine: Its high spindle speed is suitable for the processing of small tools. The torque is relatively small, focusing on the “engraving” function, such as wood (specially processed wood called wood carving machine), double-color board, acrylic board and other low-hardness boards, no Great for large workpieces with strong cutting. At present, most of the products on the market with the name of the engraving machine are mainly for processing handicrafts, and the cost is low. Due to the low precision, it is not suitable for mold development; however, there are exceptions such as wafer engraving machine.

Some people may have such a question, is the engraving and milling machine an engraving machine?

The insiders told the author that people intuitively feel that the small format is the engraving machine, and the large-format engraving and milling machine, or the engraving machine, the router, or the collective engraving machine. In fact, they are two types of machines with different structures, but the working principle is roughly the same. They are driven by three axes of X, Y and Z, and are controlled by the electronic controller.

In addition, from the purpose of use, the engraving machine is mainly used for engraving of plates, and is widely used in two-color plates or acrylic engraving. The depth of engraving is about 1mm~3mm, which is more common in the production of signs and signs. From the mechanical construction point of view, the spindle head of the engraving machine is equipped with a spring pressure nose, which is used to flatten the thin plate below 3mm during the engraving process, and at the same time, because the engraving spindle is connected to the larger diameter motor through the belt, the rotation speed is large, engraving The resulting workpiece is smoother. Due to the long tool used in the engraving machine, it is only suitable for the high-speed engraving process with a small amount of cutting.

If you use a engraving and milling machine to make three-dimensional engraving, although the drop is very large, the amount of one-time infeed is very large, and the material of 200 mm width can be completed at one time. In addition, the engraving and milling machine can flexibly select the tool diameter specification and length, and install a fine knife to dry and work hard.

Because the machine design of the engraving and milling machine pays attention to the heavy load, the frame has large steel and large Z-axis stroke, so it can not only do the process of small engraving machine, but also cut the thick plate at high speed. The amount of one-time feeding can reach 20mm~30mm. It is a process that the engraving machine can't do at all. In this sense, the engraving and milling machine can be used for both fine engraving and cutting and boring.

With its technical advantages and reasonable price, the engraving and milling machine has become an important machine tool for China's consumer electronics parts manufacturing, small precision mold manufacturing, hardware products, furniture manufacturing and other industries. In addition, in the field of high-power LED aluminum substrates, craft gifts, metal electrodes, metal frame processing, etc., CNC milling and milling machines have also begun to be used.

The treasure of art, the past and present of woodcarving

   Chinese culture is profound and profound, and has a long history. It has been inherited for 5,000 years. It has accumulated countless and inexhaustible artistic treasures. The essence of the country, wood carving art is one of the important categories. Let us discuss the development history of wood carving together.
   Archaeologists and seniors agreed that there was a transitional period of the wood age before the Stone Age. It is well known that wood is easier to process and that it is a necessity for human life in a certain period of time. However, due to the fragility of the wood, the use period is short, and it is quickly replaced by a stronger instrument such as stone. The woodcarving technique has flourished during this period and has continued to this day.
   Although modern "engraving" is already a vocabulary, it can be seen from the history of the development of creation technology that the technique of "engraving" appears earlier than the technique of "engraving" because the technique of "engraving" is simpler and easier to grasp! It can be seen that the art of woodcarving originated from the early carvings and became part of the hobbyist entertainment and spiritual sustenance.
    The history dates back to the 6th year of the Wuling area of ​​Wuling, the Daxi culture of the Neolithic Age. From the chiseled knives unearthed here, the sharp edges of the chisel are sharpened at one end, and the other end is slightly curved. Knives, combined with the functions of chiseling, engraving and drilling, can be inferred that wood carving techniques have emerged at this time. People use tools to make simple processing, use and decoration of wood, including original woodcarving totems.
    Wood carving, a long-established craftsmanship, is still loved by the general public because of its unique artistic charm. It is rooted in its profound cultural heritage.

How to use the engraving machine for maintenance?

1. Check before starting every day; if the communication line, motor line, and optocoupler line are loose, whether the voltage is stable; then turn on the power of the machine, operate the machine to move back and forth twice, and start the operation.

2. Clean the sensor (optocoupler, proximity switch) to prevent the dust powder from sticking to the sensor, affecting its sensitivity or causing false touches.

3. Clean the dust debris on the exposed rails (light rods) and clean them with No. 2 oil. After cleaning, add butter or No. 2 lithium grease.

4. After one day's work is completed, first remove the engraving knife and let the spindle chuck and lock nut be in a relaxed state. This helps to extend the life of the spindle chuck. Then we began to clean the work surface, can be cleaned with a brush; pay attention to the work surface is usually not to accumulate debris, so as to avoid deformation of the platform.

5, the water-cooled spindle engraving machine should ensure the cleaning of the cooling water and the normal operation of the pump, must not make the water-cooled spindle motor water shortage, regularly replace the cooling water to prevent the water temperature is too high, as much as possible circulating water, you can change the capacity Water tank.

6. Move the machine head to the lower left or lower right position to prevent collision, and then cut off the power; do not pull the plug with power.

7. Maintenance of the engraving machine when not in use for a long time: When the engraving machine is not used for a long time, it should be energized 1-2 times a week, especially in the rainy season with large environmental humidity, so that the engraving machine can run for an hour or so. The heat of the electrical component itself is used to dissipate the moisture in the numerical control system to ensure stable and reliable electronic performance.

8. Maintenance of the inverter: The inverter has been debugged before leaving the factory. It is forbidden to debug and change the line privately to prevent damage to the motor or inverter caused by data input error.

9. Regularly clean the cooling and ventilation system of the circuit box. Please check regularly whether the fans on the electric control box are working normally. Clean the dust in the electric control box with a vacuum cleaner regularly, and check whether the screws on the terminal block are loose to ensure the circuit is safe and reliable. use.

10. The door of the electric control box should be opened as little as possible. It is forbidden to open the door. When engraving, there will be dust, wood chips or metal powder in the air. Once they fall on the circuit board or electronic device inside the electric control box, it is easy to cause the element. The insulation resistance between devices drops, and even components and boards are damaged.

11. Regularly check whether the screws of the various parts of the machine are loose.

12, vacuum pump maintenance:

The wire mesh in the suction port of the A water circulation air pump is used to prevent the foreign dust particles from entering the pump body. The filter screen should be kept clean at any time to avoid the blockage and cause the pumping speed to drop. When the pump is not in use, it should be energized every few days. Minutes to prevent the long rust of the pump body from working properly.

B Tongyou vacuum pump should also loosen the wing nut, remove the paper filter core and clean the filter with high pressure gas regularly. It is found that the filter element is not well ventilated or damaged, and should be replaced in time. According to the length of use, the high pressure oil gun can be used to oil the bearings.

13. Operate in strict accordance with the instructions for use and comply with the safe use specifications.

The engraving machine is also alive as a human being. If the parts of the engraving machine are always in good condition, it is very important to maintain regular maintenance. This can eliminate many hidden dangers in the bud and prevent a serious accident. Operators should develop good habits that are often used to maintain equipment!

What is the laser engraving machine lens?

The laser engraving machine lens is divided into a reflective lens and a focusing lens, which are used to focus and reflect the laser.

How to adjust the laser engraving machine lens?

The first step: adjust the laser current of the engraving machine to less than 5, so that the laser power is not too strong;

Step 2: Put the dimming paper in front of the first lens, and gently press the test switch by hand (lightly press and release immediately, you can see the spotted laser spot on the dimming paper), and see if the spot falls. On the first lens (preferably in the middle), if the lens can be found, this step is completed. If you can't hit the lens or it is deflected, you need to adjust the position or height of the laser tube to meet the above criteria.

The third step: the optical path adjustment between the first lens and the second lens. First place the laser paper in front of the second lens, push the guide to the position (a) in the figure and click a test switch to see the position of the spot. Next, pull the guide to the position (b) and click the test switch to see if the positions of the two spots coincide. If it is coincident and the spot position is inside the lens, the optical path between the lenses 1 and 2 is correct; if it is not coincident, it needs to be adjusted by adjusting the adjusting screw on the frame behind the lens 1, and the two points are adjusted together.

The fourth step: the adjustment of the optical path between the lenses 2 and 3. First push the laser head to the position (c) in the figure, and put the dimming in front of the small hole of the laser head / press the test switch to look at the light shift, then push the head to the position (d) and press it again. Test the switch to see if the two marks overlap. If the two spots are in the small hole of the laser head, the light path is correct. If it is not the same point, you need to adjust the adjusting screw behind the frame 2 to adjust. The above criteria. Note: The principle of optical path adjustment between lenses 1, 2 and 2, 3 is the same.

The fifth step: the optical path adjustment between the lenses 3 and 4 (one step in the key) first remove the lens, put the glossy paper under the laser head and click the test switch to see if the spot is below the dimming paper. in the middle. If it is exactly the middle, the optical path is positive; if the spot is right, the laser tube is too low; if the spot is left, the laser tube is too high; in both cases, it is necessary to adjust the height of the laser tube to solve. If the spot is inside or outside, you need to adjust the optical path by moving the position of the laser head (there are three screws on the laser head, through which the inside and outside of the laser head can be adjusted).

Step 6: Mount the lens and the adjustment of the light path is completed.

How to adjust the laser engraving machine lens?

The principle of reflection of light, etc., the first time the debugger must follow the instructions, and consult the technical staff if necessary. In addition, the laser has a certain degree of burnability and is invisible, so be sure to pay attention to safety when dimming the road.

How to adjust the laser engraving machine lens?

The only purpose of cleaning the laser engraving machine lens is to remove the contaminants from the lens and not to cause further contamination and damage to the lens. In order to achieve this goal, people should often adopt a relatively low risk approach.

How to clean the laser engraving machine lens?

This step is necessary by first applying an air ball to blow off the float on the surface of the component, especially the lens with tiny particles and flocs on the surface. 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.

The second step is to apply a slight cleaning of the lens with acetone (or alcohol, preferably 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.

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 6% acetic acid white vinegar 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.

What are the advantages of laser engraving machine lenses for proper cleaning?

When the lens is properly cleaned and operated, its service life and performance will undoubtedly improve significantly. Taking some of the precautions and maintenance measures in this article will ensure that the laser engraving machine will work longer and perform better.

What are the precautions for using laser engraving machine lenses?

1. Never use a bare finger to install the lens. Wear a finger or rubber glove.

2. Do not use sharp instruments to avoid scratching the surface of the lens.

3. When taking the lens, do not touch the film layer, but hold the edge of the lens.

4, the lens should be placed in a dry, clean place to detect and clean, there should be several layers of cleaning paper towels or paper wipes, and there are several cleaning lens tissue paper.

5. Users should avoid talking above the lens and keep food, beverages and other potential contaminants away from the work environment.

Introduction to the two major classifications of engraving machines

In general, engraving machines are divided into two categories: laser engraving and mechanical engraving. It is divided into many small categories. Laser engraving is more advanced, and the machine is more traditional, divided into screw drive and rack drive.

First, laser engraving

Laser engraving is generally used for relatively hard objects such as stone, glass, acrylic, and can also be used for engraving. Using laser engraving on stone, you can use shadow carving or engraving text. Patterns and text can also be engraved on the glass.

Second, mechanical engraving

The range of mechanical engraving applications is wide. It can also be applied to stone and glass. It can also be used in advertising, wood, jade, metal, ceramic tiles, etc.

The engraving machine is used in advertising, cutting various words, literals, the shape of the LED light trough, or the shape of the light box, etc., and the cut words and shapes are different.

Wood carvings are familiar to everyone, wooden doors, furniture, screens or home equipment that we can all touch in our lives. The finished jade carving products mainly include pendants, various jade brands, and jade-made cymbals.

Woodworking engraving machine work environment should pay attention to

 CNC woodworking engraving machine follows the development of social economy, people's aesthetics are constantly improving, more and more advocating natural, the same solid wood furniture and wooden handicrafts have become a fashionable, CNC woodworking engraving machine as a mechanized carving of things has been rapidly developed. Solid wood furniture and natural wood grain trend, natural marking pattern, and then the wooden door and furniture which are exquisitely carved by CNC woodworking machine give a natural, fresh and elegant feeling. Solid wood decoration and solid wood furniture are also A symbol of identity, the taste of the bump.
    At present, there are many CNC woodworking engraving machines on the market, but there are not many real woodworking engraving machines. The real CNC woodworking engraving machine refers to the work that can be used to high-intensity, and can process wooden doors and furniture according to instructions. High strength, high speed and high strength. After the purchase of CNC woodworking engraving machine, the working environment of wood engraving machine is also very important, because it is directly related to the future application precision and service life of woodworking engraving machine.

    3. Use three-core power supply to ensure good grounding of woodworking engraving machine and reduce interference.
    4, the voltage requirements are stable, to prevent large fluctuations, it is best to use a voltage regulator.
    5. The machine should not be used for a long time in a strong acid or alkali environment.

How to do the woodworking engraving machine spindle shake

Different materials have the influence on the chipping speed and spindle speed of the woodworking engraving machine, as well as the overall rigidity and performance of the organic table.
Under normal circumstances, the spindle shake of the woodworking engraving machine is caused by the low speed of the woodworking engraving machine spindle, the excessive chip speed and the high product density.
When you find that the woodworking machine's spindle shakes, you only need to adjust the feed a few degrees, and a little slower, you can guarantee the quality.
The same material performance of woodworking engraving machine is done with high precision and high precision.

Engraving machine repair

When the engraving machine is not working properly, it may be a problem with its internal components or other reasons. The following is a general introduction to the problems that often arise.

(1) One of the three axes cannot move. In this case, check if the corresponding drive block of the corresponding axis is damaged. The inspection method can use the replacement method: unplug the aviation plug corresponding to the fixed shaft and insert it into the drive corresponding to the other active shaft.

(2) If the non-moving axis moves normally after the exchange, it can be explained that the drive block corresponding to the shaft is damaged, and the drive block needs to be replaced. If the axis is not moving, it means that the cable or motor is faulty. Replace the cable or motor. The three axes cannot move. At this point, check if the three-axis aviation plug is connected to the control box and the control box power is turned on. Whether the data cable is connected to the control box and the control card in the computer mainframe. If all of the above are normal, please contact the factory.

(3) The spindle cannot operate normally. First check the error code displayed on the LED display of the inverter (see the inverter error code item). The following is an example of the YIXING inverter.

YIXING series inverter common faults and treatment (1.5 kW)
