What should I do if the table top of the engraving machine is uneven? There are many ways to fix the table top of the engraving machine, including vacuum suction and fixture fixing. Vacuum adsorption is fixed by opening the vacuum pump and vacuum valve. It is more suitable for light boards, thin boards and irregular advertising boards, and can avoid the problem of precision degradation caused by vibration. Fixture fixation is to directly fix the plate with platen screws. This method is more suitable for engraving and hollowing out. Now there are engraving machines with both vacuum suction and fixture fixing.
Why should a pad be placed on the table of the engraving machine?
The table of the engraving machine is usually covered with a plate, which is usually MDF, PVC, acrylic, etc. The pad is placed on the table of the engraving machine to protect the table from damage. Once the table top is uneven, it will affect the fastness coefficient of the plate fixation, and also affect the processing accuracy of the workpiece. The countertop and the equipment are integrally connected together. Once damaged, the time and cost of replacing the countertop are not small. Therefore, we need a backing plate. Even if the backing plate is uneven, we only need to directly replace the backing plate. The time and cost of replacing the backing plate are much smaller.
What should I do if the table top of the engraving machine is uneven?
1. If the surface of the engraving machine is uneven, you can only find the manufacturer to solve it.
2. The table top of the engraving machine is flat, but the backing plate is not flat. Either replace the backing plate or mill the backing plate flat.
How to prevent the uneven surface of the engraving machine?
1. When the engraving machine is running, directly set the tool on the table of the engraving machine, so as to ensure that the knife is always down to the table without damaging the table.
2. The specific operation method is that when we calculate the path, we do not set the "engraving depth" according to the thickness of the material, but directly set it to "0mm". Before the G code file is produced, the "knife lift depth" can be set It is: lifting height + cutting material thickness.
3. For example, if the tool is set on the surface of the material, the height of the knife is 8mm, and the thickness of the processed material is 10mm, then the value of "knife lift distance" is: 8+10=18mm; the rest is except that the tool is set on the engraving machine table. In addition, other operations are also unchanged.
Through the above introduction, we have learned about the fixing method of the engraving machine table, the reason for placing the pad on the engraving machine table, the solution and the prevention plan for the unevenness of the engraving machine table.
