There are many problems when using a metal laser cutting machine, including errors in the laser cutting process, and the laser cutting effect is not good. So how did these errors happen? The following metal laser cutting machine manufacturers will answer for you.

1. Geometry error of the workpiece: due to various reasons, the surface of the processed object is undulating and heat will be generated during the cutting process. In this way, the surface of the metal plate is easily deformed, and due to the uneven surface, laser focus and surface are also generated. The position and ideal position of the surface of the object to be processed change randomly.

2. The cutting thickness of the material exceeds the standard: the cutting thickness of the material exceeds the standard. Take 3000W as an example: the thickness of the plate that the laser cutting machine can cut is less than 20 thickness. The thinner the board, the easier it is to cut and the better the quality. If the board is too thick, the laser cutter will be more difficult to cut. Under the condition of ensuring the cutting, there will be errors in the processing accuracy, so the thickness coefficient of the plate must be determined.

3. Programming error: During the processing of the metal laser cutting machine, the processing trajectory on the complex surface is fitted by straight lines, arcs, etc. There are errors between these fitted curves and the actual curves. These errors become the actual focus, and there is an error between the relative position of the machining target surface and the ideal programming position. Some teaching programming systems also introduce some deviations.

 4. Focus position error during laser cutting: In the cutting process of metal laser cutting machine, there are many factors that will change the relative position between the focus and the surface of the processed object, which is also related to the surface smoothness. The shape clamping method of the processed product, the geometric error of the machine tool and the long-term load of the machine tool will deform. The thermal deformation of the workpiece during processing will cause the laser focus position to deviate from the ideal given position (programmed position).
