Woodworking machine table top classification What are the functions of different engraving machine tops?

There are no functional differences in the functional importance of several components of woodworking engraving machine. Today we will find out the problem of the countertop of woodworking engraving machine. There are many types of woodworking engraving machines on the table, which also correspond to different market demands. What kind of work requirements are required for these worktables or what kind of purpose can be achieved by different countertops. Next, follow the CNC network Xiaobian to learn about the classification of woodworking engraving machine countertops. What are the functions of different engraving machine countertops?
Common engraving machine countertops have profile countertops, vacuum adsorption countertops, and adsorption block countertops. Profile countertops are also called fixture countertops. This type of countertop is directly pressed against the workpiece by a platen screw, which is suitable for cutting, hollowing, and the like, because vacuum suction can not be absorbed as long as the air leaks.
When customers buy an engraving machine, they can also choose the model that suits them according to the above two items. However, this is not the case. If a tool with a relatively small diameter (such as a tool of 4 mm or less) is used for cutting, it is also possible to vacuum-adsorb the table surface due to the small gap.
Woodworking engraving machine vacuum adsorption table: vacuum adsorption table is to insert a MDF directly on the table after plugging the sealing strip. Open the vacuum pump to suck the workpiece. This table saves fixed time, especially suitable for large-scale processing in the wood door industry. use. Sometimes it is necessary to put a thin Ozon board. The Ozon board is not absolutely airtight. It is formed by wood fiber and glue under high pressure. There are pipes between the wood fiber itself and the wood fiber. The gap, therefore, the Ozon board still has a certain gas permeability.
The Osong plate is placed on the vacuum adsorption table top of the woodworking engraving machine so that the milling cutter does not damage the work surface. The pressure of the workpiece close to the MDF is much lower than the atmospheric pressure of the other surface, forming a so-called negative pressure. Just as two pieces of glass are put together, the principle of separation is not easy. Once the seal is not tight, no negative pressure can be generated, that is, the pressure on both sides of the workpiece sheet is the same, and it is easy to move.
The vacuum adsorption table is not suitable for embossing, because the processing time of the embossing is generally long. If you open the vacuum pump to suck it, hehe is a little waste of electricity.
Generally, it is made into 6 partitions or 8 partitions. Each control valve controls a small partition. The advantage of this design is that if the fixed workpiece is small, all the control valves are not required to be opened, which is also to save electricity. Starting from the angle. The vacuum adsorption table is also called a suction double-purpose double table. The woodworking engraving machine adsorption block table is designed for the adsorption of irregular plates. Belongs to the custom engraving machine model.

The difference between wood fault engraving machine line fault and mechanical fault and its solution

Woodworking engraving machine line failure
 1) Performance: During the engraving process, the phenomenon of dislocation engraving and engraving in the opposite direction occur.
Solution:
In the case of power-on, quick and continuous clicks, if there is irregular motion, it is a "phase loss" fault. Check the line between the driver output and the stepper motor to find the broken line and reconnect the fault.
2) Performance: When the machine is manually controlled, the machine does not respond.
Solution:
1 Check if the data cable is securely connected. If it is loose, please connect it properly.
2 Check if the drive line interface is loose or loose, and reconnect;
3 Check if the power supply line of the host is powered off
Woodworking engraving machine mechanical failure
 1) Performance: The machine has a pause during operation, accompanied by a crisp metal sound
Solution:
1 Remove the machine casing and check the corresponding end bearing for damage;
2 Check the guide rail slide to check if the steel ball is seriously worn and damaged, and check if the guide rail has deep scratches.
3 Check the screw for damage, separate the ball screw nut from the connected parts, and manually turn the nut to feel the difference.
2) In the process of engraving, there is a misalignment phenomenon, the stepper motor runs, but the mechanical non-reaction phenomenon, please check the coupling for damage or looseness.
