The main application of metal CNC fiber laser cutting machine in the construction machinery industry is sheet metal processing. Cutting applications mainly include slender workpieces, plate parts with many holes, reserved process gaps for sheet metal parts, making sheet metal templates and drilling samples.

Application of metal CNC fiber laser cutting machine in slender workpiece.

Due to the relatively concentrated heat generated by the metal CNC fiber laser cutting machine during cutting, the heat-affected zone to the workpiece is small. The construction machinery industry uses metal CNC fiber laser cutting machine to cut the workpiece, which can effectively control the thermal deformation of the workpiece, especially for linear requirements. When the length of the workpiece reaches more than 5500mm, the "micro-connection" function of the cutting machine itself can be used to effectively control the straightness of the workpiece.

The application of metal CNC fiber laser cutting machine in plate parts with many holes.

In the construction machinery industry, laser cutting circular holes, when faced with a specific plate thickness, as long as the diameter of the workpiece circular hole is greater than or equal to the corresponding minimum diameter, and the roughness and diameter are within the guaranteed capacity of the cutting machine. All can use the laser to directly cut the material, eliminating the drilling process and improving the labor production efficiency. For some workpieces with many holes, the laser spotting function is used to determine the position of the hole, which saves the time of positioning the hole for the subsequent hole drilling process, and also saves the production cost of the drilling template, which not only improves the production efficiency, And improve the accuracy of the product.

The application of laser cutting in the process gap preparation of sheet metal parts.

The process gap reserved for sheet metal parts is also called crack relief groove or process hole. There are generally three forms of process gap design in sheet metal production: the first is that two or more bending parts are adjacent; the second is that a certain edge bending part is completely bent in the length direction. For the second process gap, a rectangle of a×b is reserved in the traditional form. If a metal CNC fiber laser cutting machine is used to directly cut a kerf with a length of a at this position during cutting, for some relatively high requirements The workpiece can be directly reserved in the form of a kerf using a metal CNC fiber laser cutting machine. The third form, when the two ends of the sheet metal part cannot be supported on the lower die of the bending machine and is in a suspended position, the workpiece will be deformed. In this case, a metal CNC fiber laser cutting machine can be used under the workpiece. A kerf is reserved for the material to prevent the workpiece from being deformed during bending.

Application of Laser Cutting in Making Sheet Metal Templates and Drilling Templates

For some sheet metal parts in the construction machinery industry, for some irregular-shaped workpieces, in order to improve the accuracy and efficiency of the detection of blanking parts, metal CNC fiber laser cutting machines are used to make blanking inspection samples, such as support angles on bulldozer rippers, excavation Machine sticks and big head plates on booms, etc. For some workpieces formed by coiling, it is necessary to use a template that matches the arc to assist production and testing during workpiece production and inspection. In order to improve the accuracy of workpiece production and the efficiency of inspection , Usually, laser cutting and blanking are used to produce samples of these workpieces, and the boundaries of arcs and straight edges are marked on the template by the scribing function of the metal CNC fiber laser cutting machine, such as the arc plate of the bulldozer, the excavation The stick of the machine, the bent plate of the boom and the bucket, etc.
