Do you know the vacuum adsorption table of CNC cutting machine

1.The vacuum adsorption effect of the CNC cutting machine plays a great role in reuse.If the adsorption effect of the machine cannot be achieved, there will be problems such as not being able to absorb the board, running the board, bursting the edge, and cutting knife marks on the board surface. It also has a certain relationship with the quality of the vacuum pump, and the processing technology of the table is also very important. The table top of the CNC cutting machine selects a good adsorption board, which is more resistant to high temperature and low temperature, is not easy to deform, does not have the problem of weak adsorption and running board, and can achieve instant adsorption and strong adsorption. It adopts double-layer table top piano key structure, and is designed with vacuum adsorption holes. More than 100 vacuum adsorption holes are evenly distributed on the table top, the adsorption force is evenly distributed, and the adsorption effect is good. After the countertop has been innovated, it is more convenient and easy to use.

2. There are several reasons why the adsorption effect of the CNC cutting machine is not ideal:

(1) Deformation:local air leakage caused by the deformation of the frame structure of the cutting machine or the deformation of the plate.

(2) Increase the effective adsorption area and negative pressure box, increase the groove area of the adsorption platform, increase the number or diameter of the simultaneous holes of the adsorption platform, and increase the diameter of the connecting trachea (the intake pipe of the vortex pump is 2.5 inches)

(3) Equipped with a filter or regularly check the deposition of wood chips inside the air pump to avoid insufficient flow caused by wood chips filling the air pump space.

Vacuum adsorption is the adsorption force generated by negative pressure vacuum. In addition to the negative pressure generated by the pump body, the tightness of all pipes will affect the adsorption effect.

In the entire adsorption equipment system, it is necessary to do a good job of sealing the pipe interface and the working surface. The adsorption effect of the same type of vacuum pump is very different between good and bad sealing.

There are several precautions for the adsorption effect of the CNC cutting machine on the countertop (taking the 1325 CNC cutting machine countertop as an example).

If the machine needs to process a separate small plate in addition to cutting the whole plate, it is necessary to divide the front table into 6-8 positive air adsorption areas, and use the sealing strip to divide the area, otherwise other areas will be ventilated and affect the vacuum degree, so When processing small parts, it will be better to turn off the valve in other areas.

If the processing of the small plate is only for engraving and not cutting, it is better to directly adsorb it on the plastic platform without adding the bottom protection plate. The thickness of the protective plate on the platform is preferably 10-15 mm, and the texture is better than the medium density board. Due to the poor air permeability of the high density board, the adsorption effect will be poor. Be sure to wrap the raw material to protect it from leaking. This position is generally overlooked by customers.

There are differences in negative pressure and air flow between vortex pump, dry rotary vane pump and water ring vacuum pump. The adsorption effect of vortex pump is good when adsorbing low density plate, and high density plate is the effect of water ring pump and dry rotary vane pump Okay.
