How to do CNC sheet metal processing well

In the field of sheet metal processing, CNC sheet metal processing is an emerging sheet metal processing method with broad market prospects; many sheet metal parts produced by CNC sheet metal processing are very popular in the market; however, CNC sheet metal processing Operation is not an easy task. To do CNC sheet metal processing well, we need to pay attention to the following points!

The science of sheet metal processing route will directly affect the quality of CNC sheet metal processing; the scientific and effective CNC sheet metal processing process route is as follows:
1. First process the reference surface, which is “reference first”, so that it can provide a precise reference for the subsequent process.
2. For the appearance with relatively high processing quality, the processing period should be well divided. Generally, it can be divided into three periods of roughing, semi-finishing and finishing to ensure the processing quality and be able to find and solve problems in time.
3. After the hole is first, it is mainly for parts such as the box, bracket and connecting rod. This can ensure the azimuth accuracy of the plane and the hole, which brings convenience for processing.

Effectively master the types of CNC sheet metal processing:
1. Laser shock technology: The laser beam is pulsed to impact the metal surface, thereby forming a plane wave, which can cause plastic deformation of the material.
2. Plastic forming technology: This technology can be divided into three types: fine-grain plasticity, phase-change plasticity, and other plasticity; the most widely used of which is the first, but it has certain requirements, mainly equiaxed fine-grained The structure should have good thermal stability, the deformation temperature should be greater than the melting point temperature of the material, and the strain rate of the device should be low.
3.Hydraulic forming technology: the hydraulic bladder is used as an elastic concave or convex mold, and oil is used as a pressure transmitting medium to perform the forming operation and process.

Remember the operating points of CNC sheet metal processing:
1. Check the drawings to see if the direction of the bending and other operations is accurate, whether there is any fault, whether the material, plate thickness, etc. are accurate, and whether the dimensions can be ensured.
2. If electroplating is to be performed, it is required that the appearance of workpieces should be treated cleanly, and there must be no doubts about shortcomings. If so, they should be processed and disposed of in a timely manner.
3. If the quality of the workpiece is in doubt, or the appearance is defective, you should check whether it can be processed and processed, and whether it will affect the subsequent processing. If it affects the processing, then the processing operation cannot be performed.
4. After the processing of the product, the necessary inspection and inspection should be carried out, if there is any doubt.
Welding is an indispensable operation link in the process of sheet metal processing. Especially for CNC sheet metal processing, the quality of welding will directly affect the quality of sheet metal processing. How to do the welding work of CNC sheet metal processing?

1. Welding labor protection supplies must be prepared. Welding equipment, welding rods, etc. must be checked to see if they meet the requirements and there are no problems.
2. The rust, grease and moisture on the weldment should be removed.
3. The weld bevel should be reasonable so as to ensure dimensional accuracy and reduce welding deformation.
4. When welding, continuous welding of long welds is not allowed. Intermittent and intermittent welding should be performed to avoid thermal deformation and affect the welding quality.
Generally speaking, the sheet metal parts of CNC sheet metal processing have good flatness, high cutting accuracy, low cost and high productivity. However, this is also based on the effective operation of data sheet metal processing; as mentioned in the above article, if you want to do CNC sheet metal processing well, you must strictly adhere to the above four aspects.
