How To Choose A CNC Router Table?

Table Types

The common types of CNC router tables include profile tables, vacuum tables, and adsorption block tables. A profile table is also called fixture table. This kind of table is to directly press the workpiece with the pressing plate screw, which is suitable for cutting, hollowing and other processes, because as long as the air leaks, the vacuum adsorption cannot be absorbed. When to buy the profile table, customers can also choose the model that suits them based on the above two items when they buy the CNC Machine. However, this is not entirely the case. If you use a tool with a relatively small diameter (such as a tool below 4mm) to cut, because the gap is small, some can also be vacuum-adsorbed on the table.

The vacuum table is to put a density board directly on the table after the sealing tape is plugged, and the vacuum pump can be turned on to suck the workpiece. This table saves fixed time and is especially suitable for mass production in the wood door industry. Sometimes it is necessary to put a thin MDF board first. It is formed by wood fiber and glue under high pressure. There are ducts or gaps between the wood fiber itself and the wood fiber. Therefore, MDF board still has a certain of breathability. The purpose of placing the MDF board on the vacuum suction table is to prevent the milling cutter from hurting the work table. The pressure on the part close to the density board is much lower than the atmospheric pressure on the other side, forming the so-called negative pressure. Just like two pieces of glass together, it is not easy to separate the same principle. Once the seal is not tight, no negative pressure can be generated, that is, the pressure on both sides of the workpiece plate is the same, and it is easy to move.

Table Sizes

The mostly used CNC router table sizes include 2' x 2', 2' x 3', 2' x 4', 4' x 6', 4' x 8', 5' x 10', and 6' x 12'.
