Many customers who need to machine woodworking projects tend to buy CNC lathes with vacuum tables when choosing CNC machine tools. So what are the advantages of a CNC engraving machine with a vacuum suction table? Which table is right for your CNC router.
The advantage of the vacuum adsorption table is that even if it is an irregular plate, it can still be tightly fixed on the table top of the CNC lathe to ensure that no vibration will affect the engraving effect during the engraving process. Obviously, the vacuum suction table will improve the engraving accuracy to a certain extent, especially for thinner and lighter sheets.
After this type of plate is fixed with a fixture, a small displacement may still occur due to machine vibration during the engraving process, thereby affecting the engraving accuracy, and the vacuum adsorption table solves this problem very well.
However, the vacuum table is not suitable for any wood. For example, thicker boards are not suitable. Such a plank is heavy enough on its own that it would be difficult to absorb. And it only needs to be fixed with a fixture to ensure that there will be no displacement that affects the engraving accuracy, so there is no need to use a vacuum adsorption table.
Another situation that is not suitable for vacuum adsorption countertop CNC engraving machine is the material that needs to be hollowed out, because the hollowed plate cannot be vacuum adsorbed and fixed. If you still want to use a vacuum table, you can lay a thin layer of MDF on the table to solve the problem that the vacuum table cannot be used for hollow engraving.
T-slot table and vacuum adsorption table have their own advantages. Choosing the right table for your CNC engraving machine can help you do your job better.
