Woodworking engraving machine daily maintenance manual



The appearance of woodworking engraving machine greatly improved the efficiency. After many customers purchased the woodworking engraving machine, they paid little attention to the usual maintenance work. When the technicians of Lulu Machinery were on-site training, they would teach the customer the precautions and Maintenance method, here is a simple explanation of the usual maintenance work of the woodworking engraving machine.

First of all: the brain part of the woodworking engraving machine belongs to the electronic equipment. The dust in the factory will accumulate in the mainframe of the computer. Especially in the summer, if the computer does not dissipate heat well, it will easily burn the circuit board, in order to keep the computer running smoothly. Also need to regularly disinfect and defragment the disk.

Secondly, it is necessary to clean the lead screw, industrial control box and circuit board regularly, and clean the work surface in time, including the material debris next to the guide rail and the guide rail to prevent the machine from appearing during the working process due to debris interference.

Again: slowly move back and forth after adding oil to ensure that the lubricant can be evenly applied to the guide rail and the lead screw. If the machine is not used for a long time, it should be refueled regularly to ensure the flexibility of the transmission system. First clean the rails and lead screws, and use a cloth (without hair removal) to clean off the oil and material scraps on the rails and lead screws. Due to the low temperature, both the guide rail and the lead screw can be added with oil. It is best to add antifreeze oil. The refueling cycle is twice a month, that is, every two weeks. Add cooling water or coolant to the CNC economic woodworking engraving machine, and keep the cooling water free of impurities.

Finally: When using woodworking engraving machines in winter, be sure to pour out the water in the tank when not using the machine to prevent the water tank and water pipes from freezing. The temperature of the operation workshop is preferably higher and higher, and the winter is likely to cause ice formation in the woodworking machine water tank. The temperature has little effect on the woodworking engraving machine, but because the user adds butter to the screw, the winter also forgets to clean up, which leads to the opening of each boot. Some studios have very low temperatures. Although the oil is added, it can still be frozen. On, the machine can't run.

What are the control methods for woodworking engraving machines?



There are three types of woodworking engraving machines on the market:
First, the use of single-chip control, woodworking engraving machine can be typeset at the same time, but can not turn off the computer, can reduce the waste caused by computer misuse.
Second, the use of USB port to transfer data, the system has more than 32M of memory capacity, save the file can be completely off the computer, turn off the computer or other typesetting, can greatly improve work efficiency.
Third, all computing work is done by computer control. When the woodworking engraving machine is working, the computer is in working state, and other typesetting work cannot be performed. It may cause waste due to misoperation of the computer.

Woodworking engraving machine double-layer countertops can not hold the board




Nowadays, many furniture manufacturers have found that when the demand for sinking or double-layered countertops is being made, sometimes the opportunity of woodworking engraving cannot be absorbed or the adsorption is insufficient. What is this? Considering that most woodworking engraving machines now use vacuum adsorption technology, if there is an inability to absorb the sinking and double-layered mesa, it is mostly due to insufficient adsorption. Next, follow the CNC network Xiaobian to learn about the wood-based engraving machine double-layer tabletop production can not absorb the relevant content of the board!
The vacuum adsorption table is connected by a vacuum pump to the bottom of the woodworking engraving machine. There are a plurality of adsorption holes on the surface of the engraving machine. When we put the board on top, the board is firmly absorbed by the vacuum generated by the vacuum pump. On the countertop, the engraving machine starts working at this time, and the whole loading and unloading process is no more than ten seconds, which is efficient and fast. Ideal for line carving of wooden doors and panel furniture.
First, first check whether the motor line voltage is normal;
Second, 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;
    Third, the vacuum pump inside the filter blockage cleaning;
    4. The countertop or pipe has a gas leakage phenomenon;
    5. Reverse the change of the UVW on the motor to change the direction of rotation of the motor.
6. The processed object is too small to encrypt the vacuum valve port;
7. Use a MDF between the table top and the workpiece;
The profile fixture table top is a fixed way to fix the workpiece on the table surface by manually tightening the screw. The profile table top is a bottom layer with an aluminum profile with a T-slot and a PVC material on the top. If the material shape is irregular, the vacuum adsorption is not easy to fix or the processing technology is embossing, hollowing, cutting, etc., then it is more suitable for the profile fixture table. The embossed print itself has a long carving time, and does not care about the fixed time of the artificial splint for a few minutes, and the hollow embossing and cutting process is vacuum pump can not absorb. Woodworking engraving machine for profile fixture table top is suitable for embossing crafts; hollow partitions, screens and other home decoration; advertising industry PVC, acrylic, two-color plate cutting and so on.
If it is a blanking piece, the last may be because the workpiece is too small, the suction force can not be fixed, because the vacuum of the small piece to the last vacuum suction channel, the supporting force of the surrounding plate to the small piece is also small, will definitely Loose. In this case, nailing assistance can be used. If the size is relatively large, an Ozon board can be laid underneath, and the board to be machined is nailed to the upper side for auxiliary fixing.

Broken knife analysis of woodworking engraving machine



    There are two kinds of broken cutters for woodworking engraving machines. One is to engrave high-hardness materials for a long time. The wear and cutting edges of the cutters are inevitable. The cutters are worn out, and the depth of engraving certainly cannot meet the set requirements. : The tool is broken, how to replace the new tool with two new tools, how to engrave the next, these are very real problems.
    These two common phenomena can be classified as one problem. It can be understood that the case where the tool wear is quite serious is equivalent to the broken edge state. We can handle it in the same way. When we find that the tool suddenly breaks during the operation of the woodworking engraving machine, please stop or stop the operation in time. Then remember the current block number, which is used later. After the spindle is completely stopped, replace it with a new one. Because we are manually changing the tool, it will inevitably lead to a change in the height of the Z direction. We only need to use the tool block to re-determine the Z direction origin. There is no change in the X and Y directions, so we don't have to. After the determination is complete, we find the "Advanced Start" function under the operation menu. The dialog asks us to enter the start line number. This number is the number we wrote down when we started the machine. We need to input the start number. It is smaller than the number recorded, and the specific size is determined according to the time we found the broken knife. If you find out later, you will lose some numbers. End segment number default file is OK. In this way, the wood engraving machine can automatically continue carving along the unfinished part.

How to extend the life of laser engraving machine laser tube



With the use of laser engraving machines, people are accustomed to using laser equipment in many places, but with the use of everyone, some problems will arise. Some equipments are impossible to use because of the revenue problems they generate. Expensive imported laser tube, so after a period of use, the laser tube will be aging, the performance of the corresponding laser equipment will also be reduced, let us look at how to effectively prevent the aging of the laser tube.
For example, the laser woodworking engraving machine that we often use, after a period of time, the power of the laser tube will become low after aging, and some things will not be cut if the speed is slowed down. It is inevitable that the laser tube will age after use. All we can do is slow down its aging and prolong the use of the activated tube.
1. Minimize the power used when the cutting requirements can be met.
2. Minimize the number of times the laser is turned on and off.
3. Turn off the laser during non-working hours.
4. Try to ensure that the temperature and humidity of the workplace meet the requirements for equipment use.
5. Do not operate the equipment for an extended period of time. As mentioned above, if we pay attention to the above problems in the process of using laser equipment, we can maximize the service life of laser products.
