There are many types of CNC Router on the market, including splint type fixed table top CNC Router and vacuum adsorption type fixed CNC Router. Users can choose the most suitable model according to their engraved products.

1. Open the vacuum valve and do the next test. It will be found that the effect of adsorption of flat wood is better. However, the adsorption effect on curved and uneven plates is not good.

2. Engraved wooden door products, embossed and other impenetrable products have good adsorption effect. However, the absorption effect of hollow carving products that are carved through and carved through is not good.

3. In terms of time, manual fixation takes 2-4 minutes. The vacuum adsorption takes only 1-2 minutes. Time is better than manual fixation.

4. The price of vacuum adsorption is relatively expensive. The vacuum adsorption type is composed of a vacuum adsorption table and a vacuum pump. In the market, there are generally six zones for vacuum adsorption, and eight zones for vacuum adsorption. The vacuum suction table is composed of a piece of wood with a thickness of about 5 cm, and the material is very hard. Punch six or eight holes on it to achieve the function of strong suction. The general power is 5.5KW, and the higher the power, the stronger the adsorption capacity. When the woodworking board is placed on the countertop, the vacuum adsorption countertop can directly absorb the woodworking board directly. It is not necessary to manually fix it with a card board. But not all users are suitable for vacuum suction tabletops.

1) It is only suitable for users who are not hollow carvings, such as wooden doors, relief carvings, etc.

2) If it is a hollow lattice, it is recommended to use a common cardboard table to fix it.

3) The vacuum adsorption table is prone to defects such as insufficient suction and air leakage.
