Safety and maintenance essentials for woodworking engraving machines

    The role of the machine is for humans, which can greatly improve the efficiency of human production. From the current point of view, the traditional handicraft industry - woodworking engraving, has now achieved mechanized production, the application of wood engraving machine in this field has been very common. Although this type of machine is currently used universally, not everyone can master the safe use and maintenance of the machine.
    Woodworking engraving machine manufacturers in the safety essentials of the use of the machine, the key to remind the operator to check the machine before the operation, to confirm whether the machine can run normally. And at the time of operation, if there is a problem with the machine itself, stop the operation of the machine immediately. At the same time, for the sake of personal health, it is necessary to wear a mask.
In addition to the highlights that need to be paid attention to in the safety essentials, the operator is reminded to pay attention to the maintenance essentials, that is, the problem of oiling. Sometimes I buy a machine, because it will not be put into use for various reasons. I need to pay attention here. Even if it is not applicable, maintenance of the machine is also necessary. Machines that are not used for a long time are required to be lifted and lubricated, otherwise they will easily rust and the machine will be easily damaged.
    Of course, in addition to this, you need to pay attention to the use time of the machine, and you can't work continuously for more than one hour every day. Otherwise, the cooling of the machine will not keep up, which will easily lead to safety problems.

Woodworking engraving machine has the reason of broken knife, correct operation

    Woodworking engraving machine is one of the more common equipments in wood processing machinery. It adopts computer controlled form and works well. It is widely used in woodworking industry, advertising industry and mold industry. The operation of the engraving machine is more demanding. Inappropriate use will inevitably lead to accidents. For example, what happens to the engraving machine?

    There are many reasons for the broken knife in the woodworking engraving machine. The first is the problem with the machining program. The general woodworking engraving machine is operated by the machining instructions, covering the position command and the speed command. If the program itself has a problem, this will directly affect the operation of the engraving machine, and the broken knife phenomenon will occur. Of course, if the machine itself is not in a normal operating state, it will also cause the equipment to malfunction, which will affect the actual operation.

    From the point of view of the current broken knife, in addition to the failure of the equipment itself, such as tools, materials and workpiece clamping, etc. are also the cause of the broken knife. For example, the tool clamping is not neat, the hardness of the material is not uniform, and the clamping is not firm, etc., which will directly cause the cutting machine to break the knife, which will affect the actual processing efficiency.

    The reason why the woodworking engraving machine is broken is similar. In the operation, there should be a specific understanding. According to the introduction of the wood engraving machine manufacturer, different reasons are used to analyze the cause of the problem, and the long-term use of the engraving machine is guaranteed. Operational efficiency.

Misalignment of the engraving machine

  The engraving machine may encounter various misalignment faults during the engraving process, such as the left or right side of the engraved sample pattern, which is called the left and right misalignment; for example, the upper or lower pattern of the engraved sample pattern is wrong, called upper and lower. Misalignment; for example, in the process of engraving, the X (Y) axis direction is stuck, chaotic, and walking is not normal, which is called X (Y) axis misalignment; for example, the surface of the engraved sample is uneven, and the wave pattern is the Z axis (control spindle) Up and down direction) misplacement, etc.


    The reason why the engraving machine is misplaced
    There are many factors that affect the normal operation of the engraving machine, including the driver, voltage, interface board, main board, adapter board, spindle motor, machine tool itself and wires. These factors may cause misalignment during the operation of the engraving machine. The problem.


    1, the problem of the drive: the structure inside the drive itself or the problem of the electronic original device will also cause misalignment, this is the most; if the number of occurrences is not much, and the speed is reduced a little, sometimes can be carved normally, which means that the drive has not It is completely broken; if it is misaligned at the beginning, it means that the drive is completely broken. Solution: Repair the drive or replace the drive.

    2, the voltage problem: the engraving machine needs a lot of power when working, if the voltage is too low, the power supply to the driver is insufficient, the power will not reach the misalignment phenomenon, this situation is generally more than the Y-axis misalignment, this occurs The phenomenon may be that the external voltage is not enough, or someone using a high-power device such as electric welding on the same line. Solution: Install a 5000 watt regulated power supply, but the error range of this regulated power supply should not exceed 5%, preferably within 3%.

    3, the interface board, the motherboard, the adapter board problem: If the interface board, the motherboard, the adapter board is broken, the engraving machine in the process of working, a certain direction or the three axes are not moving, resulting in the engraving misplacement.

    4, the problem of the spindle motor: If the stepper motor or the servo motor problem, the whole machine does not move in a certain direction, the hand screw can not turn.

    5, the problem of the machine itself: a certain part of the machine tool has problems or loose, the surface has impurities, etc. will also be misaligned; if the coupling is loose, broken, there will be misalignment; rails, long time on the screw Misalignment can occur if there is no cleaning and refueling; if the machine tool line is broken, misalignment will occur.

    6. Poor contact of each part of the control line (power control line transmission line). Solution: Remove all connections and reinstall them.

How to operate the engraving machine

 1, according to customer requirements and design requirements for typesetting, after the path is correctly calculated, save the path of different tools. Save as a different file.

2. Open the path file in the engraving machine control system after the check path is correct (previewable).

3, fix the material, define the origin of the work. Turn on the spindle motor and adjust the number of revolutions correctly.

4. Turn on the power and operate the machine.

Power On 1. Turn on the power switch, the power indicator lights, the machine first resets the self-test, X, Y, Z, and the axis return to zero, and then each run to the initial standby position (machine initial origin).

2. Using the handheld controller, adjust the X, Y, and Z axes separately to align the starting point of the engraving work (processing origin). The spindle speed and the feed speed are appropriately selected to keep the engraving machine in the work waiting state.

Engraving 1. Edit the file you want to engrave.

2. Open the transfer file and transfer the file to the engraving machine to automatically complete the engraving of the file.

End When the engraving file is finished, the engraving machine automatically raises the knife and runs to the top of the work start point.

What is the similarity and difference between CNC engraving and milling machine and CNC engraving machine?

     

       The engraving and milling machine is a kind of CNC machine tool. It is a CNC machine tool that corresponds to a traditional engraving machine. They believe that the engraving and milling machine is a CNC milling machine for small tools, high-power, high-speed spindle motors. The advantage of the engraving machine is engraving. If the hardness of the machined material is relatively large, it will be difficult. 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 and milled. It is a high-efficiency, high-precision CNC machine tool. Sharp is an outstanding generation of engraving and milling machines and CNC engraving machines.




      Small CNC engraving machine: suitable for small high-speed spindle machining tools, the torque is relatively small, focusing on the engraving function, such as wood (wood processing, especially wood carving machine) board and two-color board, the hardness of the acrylic board is not high, the workpiece is not suitable Strong cutting. At present, most of the products of the engraving machine on the market are mainly processed crafts, and the cost is low. Due to its low precision, it is not suitable for mold development, but there are exceptions, such as wafer engraving machines.




      Maybe someone will have this problem. Is the engraving machine an engraving machine?

      The insiders told the author that people intuitively feel that the small format is an engraving machine, and the large format is an engraving machine, an engraving machine, or a router, or simply a large engraving machine. In fact, they are two different machines, but they work roughly the same way. They are driven by three axes of x, y and z and are controlled by an electronic controller.




      In addition, from the purpose of use, the engraving machine is mainly used for plate engraving, such as: woodworking engraving machine, engraving machine, aluminum plate engraving machine, four-axis, five-axis engraving machine engraving machine, engraving machine, relief engraving machine, CNC wood engraving machine, Engraving machines, tombstones, etc. It is widely used in two-color plates or acrylic engraving. The depth of engraving knives is about 1mm~3mm. The logos and signs used are more common. From the mechanical structure 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 3 mm during the engraving process. At the same time, since the engraving axis is connected to the larger diameter motor through the belt, the speed is larger and the engraved workpiece is smoother. Due to the long tool used in the engraving machine, it is only suitable for high-speed engraving processes with low cutting ability.




     If the engraving machine is used for three-dimensional engraving, although the reduction is large, a large number of knives, 200mm wide material can be completed at one time. In addition, the engraving and milling machine has the flexibility to select the tool diameter and length specifications, slowly drying with a fine knife, and working with a thick shank. .


     Because the design of the engraving and milling machine is mainly focused on heavy loads, large steel frames and large Z-axis strokes. Therefore, it can not only make the technology of the small engraving machine, but also cut the high speed and feed rate of the plate, which can reach 20mm ~ 30mm at a time, which is a process that the engraving machine can't do. In this sense, engraving machines and milling machines can be finely engraved, and cutting, engraving and milling can be done.


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

What are the specific steps for using the advertising engraving machine?

1. Double-click to open the engraving software and set the layout according to the material size in millimeters.

2. Edit the file in the space area of ​​the page.

3. After making the file, place it in the position of the material to be processed to generate the desired processing path.

(1) The 2D path is two-dimensional engraving. Generally, the engraving depth of the two-dimensional engraving is fixed, that is, according to the engraving depth of the design, the milling process is performed from the surface of the object, and finally the ideal effect of the design is achieved. The specific operation is as follows: point 2D pop-up two-dimensional engraving mode dialog box, select "intaglio" in the "engraving depth" to set the depth to be processed, and select the tool compensation. The engraving method selects “horizontal milling bottom” to select the knife through the tool magazine, and the secondary machining method selects the hook edge, and also selects the same knife through the tool magazine. Select counterclockwise, and select the automatic check error and automatic decomposition self-intersection ring, point to complete the path creation, then the computer automatically calculates the path, which is the green part. (Note: If there is no required tool, fill in the corresponding parameters in the "Tool parameters" column, click "Add tool" - "OK". This will add a tool).

(2) 3D path is three-dimensional engraving, three-dimensional engraving, which means that the system automatically changes the depth of engraving according to different graphics and tools, ensuring that the engraved surface is consistent with the design object. Commonly known as the "three-dimensional clear angle" function. The specific operation is as follows: point 3D pops up the 3D engraving mode dialog box, and selects the depth of the "inscription" in the "engraving depth". Remove the checkmark in front of the "rough knife milling". In 3D finishing, the tool is selected by the tool magazine, and most of the centering tools are selected. Select counterclockwise, and select the automatic check error and automatic decomposition self-intersecting ring, and click to confirm the completion path creation.

(3) The word cutting path actually refers to cutting the object to be processed from the engraving material by using a milling cutter. The usual processing methods are processing on the inside and outside contours. The “outer profile” is cut along the outside of the designed graphic. The cut part is the designed figure. The "inner contour" is cut along the inside of the designed pattern. The part left is the graphic designed. When the inner and outer contours are being cut, the Wentai system automatically sorts them and counterclockwise and clockwise directions. “Original line output” means that the design graphic is output as it is, and single line words and graphics must be output as they are.

Operation mode: Select the contour according to the need, use the outer contour when cutting the word, use the inner contour when hollowing out, or use any contour when using the center sharp knife when 3D inverted. The depth of engraving is generally 0 when cutting, the knife is on the table top; when it is inverted, set the depth according to the need, the knife is on the material. Select tool compensation. Use the same hour hand when making the panel and the bottom plate.

4. After checking the correct path, click the “Save engraving path” pop-up window. When the “lifting knife distance” is cut, the material thickness is increased by 7~9. In the “output only selected part”, check the number and click “Output file”. Find", select the Chunlan disk location to be saved after popping up the dialog box, select "G-codefiles(*.nc)" after "Save Type", enter the file name after "File Name", and click "Save" to return to the window. , click "Confirm".
