Finishing woodworking engraving machine tool wear, purchase method and extending service life

After the use of woodworking engraving machines, some customers reflect the wear of the tools during the use of the tool. Then how to reduce the tool wear of woodworking engraving machine and increase the service life of the tool. In addition to solving these problems, we also helped you to sort out the precautions for purchasing woodworking engraving machine tools.
 First, woodworking engraving machine tool wear
The main reasons that affect the tool wear of woodworking machine are as follows:
1, cutting amount: including spindle speed, feed rate, path spacing, knife depth and other parameters.
2, tool type tool data: select the appropriate tool for the machining depth and its angle, material
3. Direction of the cutter: The design of the engraving program must be related to the use of the cutter.
4, the knife way: according to the material must choose the appropriate knife direction.
5. Cutting fluid: The method of auxiliary engraving must be appropriate.
Second, woodworking engraving machine tool wear judgment
1, according to the movement state of the engraving machine in the process to determine the wear condition of the tool, such as processing parameters, cutting amount and other settings are reasonable, the engraving machine in the processing vibration is very large, and a "beep" sound, you can be sure The tool has reached a state of rapid wear and must be changed immediately.
2, woodworking engraving machine tool wear, the amount of wear, the most important and most direct way to distinguish is to "listen" sound, if the cutting sound is very "heavy" or issued a "screaming and harsh" sound, indicating the processing status of the tool If it is not normal, the machining can be stopped at this time. If the tool quality problem, the tool clamping problem, and the tool parameter problem are removed, it can be proved that the tool is worn out, so it is necessary to suspend the machining and change the tool.
Third, extend the life of woodworking machine tool
In the work of woodworking engraving machine, tool wear and broken knife are inevitable, how to extend the service life of the tool! Changsha Xinye CNC Equipment Manufacturing Co., Ltd. summarized the following points:
1. Choose the right tool: For the high hardness material, use the corresponding tool, otherwise it is easy to break the knife.
2, the maintenance of the tool: the processing must be properly kept in the tool, ready for the next use of the tool. When employees get off work, be sure to separate the tools and materials.
3. During the engraving process, the tool broken inside the material should be taken out in time, because when we re-engraving, it is not necessary for the engraving knife to hit the short knife and break again.
4. Engraving speed: When carving high hardness materials, do not cut the knife too fast.
Fourth, choose woodworking engraving machine tool precautions
1. Choose according to tool complexity, manufacturing and sharpening cost: the tool life of complex and high precision should be higher than that of single-edged tool. For multi-knife engraving machines, combination engraving machines and automatic machining tools with complicated tools, tool changes and tool adjustments, the tool life should be selected higher, especially for tool reliability.
2. When the productivity of a certain process in the workshop obviously limits the productivity of the whole workshop, the tool life of the process should be selected lower; when the total expenditure of the whole plant is shared in a certain process, the tool The life expectancy should also be chosen lower.
3. In the case of large-scale finishing, in order to ensure that at least one pass is completed and the tool is changed midway during cutting, the tool life should be determined according to the accuracy of the part and the surface roughness.

How to judge the abnormality of the working sound of the engraving machine?

     The engraving machine stepper motor has a pause every step of the way, and the noise is normal.
     At a certain frequency, the engraving machine also generates resonance of the body, emitting obvious noise. This type of noise does not affect the normal use of the machine.
     The noise that affects and is harmful to the engraving machine is mainly manifested in the following two categories:
     1. Abnormal noise is emitted when the spindle motor is running.
     The generation of such noise proves that there is a quality problem in the spindle bearing or the service life of the spindle bearing has arrived, or the quality is degraded or damaged after wear, and replacement can be considered at this time.
2. Abnormal noise is emitted when walking axially. This type of phenomenon is mostly present on the X axis.
     Mostly the axial motor bearing is damaged or the X-axis guide rail lacks lubricating oil, dirty, too tight, ball wear, ball drop, etc., must be handled in time.

Control the working speed of the stone engraving machine

Friends of the stone processing industry know that the amount of stone products that stone engraving machines can process in a certain period of time affects the cost and profit of the products. So how can we control the efficiency of processing and freely control the processing cost?
We must know that the most important point of processing stone is to determine a reasonable cutting amount according to the hardness of the engraving material and the performance of the stone engraving tool, which is the depth of each layer that we usually say. Each tool of different materials will have a maximum amount of knives. When we use the stone engraving machine, we should try not to use the maximum knives of the tool. If the machine is in the limit state for a long time, the tool will be damaged faster. Moreover, the speed is not improved when the maximum amount of knife is processed, and the speed is likely to cause the knife to be broken. Therefore, we have to set the amount of undercut to 2/3 of the maximum amount, so that the tool life will be greatly increased, and the processing speed can be improved a lot; thus, the tool cost can be saved and the processing efficiency can be improved.
We can also carry out roughing and then finishing according to the actual situation. When roughing, we can cut off all the allowance as much as possible to save the finishing time. It can also use the tool material with better processing performance. The performance of the stone engraving machine is not only reflected in the hardware configuration of the machine, but also requires us to accumulate processing experience little by little to improve the processing efficiency.
6. Keep the fire extinguisher at your fingertips; turn off the laser or shutter when not working; do not place paper, cloth, or other flammable materials near the unprotected laser beam.
7. After starting the machine, the machine should be started in the low speed X and Y directions to check if there is any abnormality.
8. Wear protective equipment as required, and wear protective glasses that meet the requirements in the vicinity of the laser beam.
9. Stone engraving machines should not process a material before it can be irradiated or heated by laser to avoid potential danger.
10. After entering the new part program, you should try it out and check its operation.
11. Observe high pressure safety regulations when servicing. Every 40 hours of operation or weekly maintenance, every 1000 hours of operation or every six months of maintenance, in accordance with the regulations and procedures.
12. Obey the general safety rules of stone machines. Start the laser in strict accordance with the laser start-up procedure.
13. Operators must be trained to familiarize themselves with the structure, performance, and knowledge of the operating system.

On the importance of cooling in the processing of stone engraving machine

Most of the CNC stone engraving machines on the market now use double cooling, and what is the role of adding water during stone processing? In fact, because the material of the stone is relatively hard, it needs a water-cooled cutter during the engraving process. On the other hand, the water-cooled engraving machine spindle is used to prevent the temperature of the spindle from being too high and to provide a certain protection. If the operator of the engraving machine does not pay attention to the cooling or does not follow the steps, it will easily lead to the situation that the stone engraving machine does not pass the water and dry, causing serious damage to the equipment.
 The CNC stone engraving machine must adopt the cooling method during the processing. If the engraving machine is not cooled by water, the main shaft will always be in a state of continuous high temperature heating. It is easy to cause the spindle of the engraving machine to be shaken or misplaced, the speed of engraving is fast and slow, and the processing is very unstable. The stone carving machine spindle will directly affect the precision of the engraving, and if the spindle is misaligned, the engraved workpiece will be misaligned, and the processed stone will be seriously affected.
 
  If the shaft of the stone engraving machine is dry, the spindle will be overheated, causing the spindle of the engraving machine to burn out due to excessive temperature. The spindle is an important part of the engraving machine. If damage occurs, you need to return to the factory for repair or replace it with a new one. Whether it is repairing or replacing, it will seriously delay the processing period of the stone engraving machine, especially when the order quantity is large and the construction period is tight, because the engraving machine can not operate normally and cause serious damage to the enterprise. Therefore, the stone engraving machine must follow the formal operation of the manufacturer's training in the process of processing to ensure the safety of the equipment, in order to bring greater benefits to the enterprise.

What is the problem with the engraving position of the engraving machine?

      Sometimes when using the engraving machine, I found that the position of the engraving is wrong. I always blame the wrong position. To eliminate this problem, we must first check the reason. The following methods can check out what is wrong.

      1. Check if the belt is loose and the synchronous wheel is slippery.

      Second, X, Y two-axis racks have clearance

      Third, check the driver and motor

      Fourth, the drive line is loose. Try to fix it tight.

      5. The limit switch fails. When the system returns to the original point of the system, the limit switch is closed and popped open, and the limit switch can be changed.
