What's the matter with the end of the copper sheet being lifted when cutting, and how to solve it? In the production and processing of copper plate, it is always necessary to cut the copper plate to the required size, so the specific cutting in the copper plate cutting process is very important. Some practical operators experience end warping. Here are the steps to take.


The reasons for the warping of the copper plate ends:

When machining slender shapes on copper plates, thermal deformation is prone to occur, mainly due to the heat generated during the machining process. The main reason for the warping of the machined end due to the falling of the machined object is mainly due to the poor positional relationship between the tines or the plate-shaped bracket and the machined part, resulting in the bracket being unable to support the part.


If the cutting head moves up and back quickly after reaching the processing end, the contact can be avoided to a certain extent, but it increases the time required for the cutting head to move upward, and solves the problem of thermal deformation caused by copper plate cutting. With the development of processing, the thermal deformation gradually increases. Increase, there is essentially no contact between the nozzle and the part during machining. At the end of machining, the part can easily come into contact with the nozzle due to the large deformation of the part and the base metal as they break

The solutions are as follows: ① There is a micro-joint at the end of the part, and the part is not completely cut off; ② The machining head is not allowed to stop at the end, but pass through the end

 After the B method solves the warpage caused by the drop.

Adjust the positional relationship between the machining shape and the workpiece support so that the support can support the part, and micro-joining is also an effective method. The so-called micro-joining is to leave a small amount of cutting residue during the copper plate cutting process, that is, stop processing before the end of processing. This will add to the process of separating the microconnections after processing.
