What are the influencing factors of abnormalities in the use of CNC cutting machines?

The cutting accuracy of the 　　 CNC cutting machine is relatively high. When in use, it often causes some problems in the overall cutting accuracy due to some operational reasons, which will seriously affect the cutting quality of the workpiece. One of the more common ones is some errors produced when the cutting machine cuts the workpiece. Next, the CNC cutting machine manufacturer will give you a specific introduction to the influencing factors of abnormality when the cutting machine is used.

　　1. Programming software error:

　　 The NC code generated when the programming software is defective or has no cumulative error compensation function wrong.

For example, the generated code size data is wrong or the compensation direction is wrong or the code has accumulated error. There is no problem in a small range of size, and there is a large error in the case of many line segments. The lead-in and lead-out of the formation of the incision are deviated Phenomenon, the problem of checking the deviation of the workpiece spacing in the full-plate jacket is very simple. If the numerical control code is converted into a CAD pattern, the compensation direction can be known through simulation.

　　2. Graphic size error:

　　 In the process of drawing and setting, pattern size error may occur due to negligence. In this case, you can find the cause by checking the size.

　　3. Errors caused by coedge:

　　 CNC cutting machine manufacturers mentioned that when coedge is used for cutting, the compensation amount, the actual slit width, and the distance between the workpieces on the coedge must be consistent , If they are inconsistent, the size of the workpiece may become larger or smaller.

　　4. Nozzle quality and slit correction amount:

　　 The quality of the nozzle affects the surface quality of the workpiece and the flatness of the cut side. The slit compensation needs to be compared with the actual cut slit The width is the same.

The way to reduce such errors is to choose a nozzle with qualified quality, and the nozzle size should also be suitable for the thickness and material of the sheet to be cut.

First of all, the slit width is uniform, the cross section is flat, does not stick to sludge, and then it is not compensated for the 1-foot rectangle, and then measured to supplement some slit width.

　　5. Deformation during cutting:

　　 Deformation mainly includes thermal deformation and gravity-induced deformation. Using a reasonable lead position and cutting direction during programming can reduce deformation, and can be added if necessary The cooling device adopts a cutting platform with a reasonable structure.

　　 The above are the factors that affect the abnormality of the CNC cutting machine introduced by the CNC cutting machine manufacturer. If similar problems occur during use, they can be dealt with in time. Data errors It is better to change, but if it is the problem of the cutting machine itself, you need to find someone with many years of experience to deal with it in time.

In today's world, have risen to an unexpected level of punching machine manufacturer. It has gained a lot of popularity and has come up with different kinds of variations in its content.
