CNC engraving machines are mainly divided into aluminum profile tabletop engraving machines and vacuum adsorption tabletop engraving machines according to their different tabletops. The former uses aluminum profiles as a countertop, while carving workpieces require manual fixation with rivets. This fixation method is slower and requires re fixation every time the material is changed. However, for small-sized materials, the fixing method of the T-groove table is more convenient.

The vacuum adsorption table uses a vacuum pump to fix the material. Place the material on the vacuum table, turn on the vacuum pump switch, and the material can be fixed through gas adsorption. This method is more secure for the fixation of the board and saves more time. For batch processing of large plates, it can greatly improve workshop efficiency. Of course, the type of woodworking carving machine to choose depends on the processing materials and process.

The CNC engraving machine for vacuum tabletop consists of a vacuum workbench, a vacuum area control switch, and a vacuum pump. There are multiple suction holes on the vacuum tabletop, which are connected to the vacuum pump through pipes at the bottom of the tabletop. They enable the engraving machine to have vacuum adsorption function. Therefore, when workers place the board on the vacuum workbench of the carving machine, the processed material can be firmly adsorbed on the workbench through the negative pressure generated by the vacuum pump. The entire process takes less than 10 seconds and can greatly improve work efficiency.

But not all boards are suitable for fixation through vacuum adsorption, and it is not suitable for hollow processing, or for curved or uneven carved workpieces. A vacuum workbench is suitable for processing wooden boards with a thickness of about 30mm. If it is too thick, it can lead to a decrease in adsorption efficiency.

The vacuum countertop is divided into multiple areas, usually four, six, or eight, which can greatly enhance the adsorption function of the countertop. The woodworking engraving machine AKM1325 usually has four areas, and the larger the machine size, the more areas there are. Each area has its corresponding switch valve, and we can easily open and close the vacuum zone through the controller. When we process the sheet metal, by opening the vacuum valve, the carved sheet metal will be directly fixed, saving a lot of time compared to manual fixation, and the fixation is more stable, suitable for wooden door processing and large sheet metal relief carving.

The commonly used vacuum pumps have a power of 5.5KW or 7.5KW, and your engraving machine has a larger size. You can choose multiple vacuum pumps to achieve good plate adsorption effect.

Through the above introduction, you can understand the advantages of vacuum table engraving machines. However, not all processing is suitable for using a vacuum workbench. If you need to process materials with irregular shapes or hollow processing techniques, the T-shaped groove countertop will be more suitable for your work. The woodworking carving machine with T-slot fixture tabletop is suitable for home decoration such as hollow partitions and screens. When processing small plates, the T-shaped groove table is also more suitable. Because using a vacuum table to achieve better adsorption effect requires blocking other unused suction holes, which is more time-consuming than using a T-slot fixture.
