When using machines and equipment to process sheet metal cutting materials at a precision CNC sheet metal fabrication manufacturing plant, care should be taken to ensure that the hydraulic shear error is within your control.

When using machines and equipment to process sheet metal cutting materials at a precision CNC sheet metal fabrication manufacturing plant, care should be taken to ensure that the hydraulic shear error is within your control. If you can't control the error of your hydraulic shear, you can't use it. Errors only come with operation. No error is impossible, only this error shall be a value that everyone can manipulate.

In addition, the production and processing of machining centers and pasteboards are very important and problematic in precision CNC sheet metal processing. If we can control the arc error of precision CNC sheet metal processing, it will be more and more favorable to our operation process. Now do we have a long-term grasp of the relative error of precision CNC sheet metal processing. Although the general components are relatively small, but in a large family, they can not be underestimated. No matter how small the fly is, the whole process is very complex. Therefore, a more careful process is necessary for everyone involved. Precision CNC sheet metal fabrication today is a precision machining specialty. You have to be careful during the manufacturing and machining process in order to avoid some big mistakes. Therefore, if you use Precision CNC Sheet Metal Processing, you need to check not only its tensile strength, but also the degree of fatigue elimination and some related properties. It has complex composition, so we should use more detailed raw materials. According to the development trend, there are some methods to reduce the error of components

1. Methods to prevent die-cutting: ① Use special anti-peeling concave mold. ② It is often cut in production to keep sharp and demagnetize. ③ Widen the die clearance. ④ Inclined tooth surface die instead of flat tooth surface die

2. Important reasons for rapid damage to the mold base: ① Mold clearance is too small. It is generally recommended that the total mold clearance be 20% to 20% of the raw material plate thickness. ② The acidity of the convex and concave molds is not good, which is caused by the lack of precision of the mold base, the main parts of the mold and the CNC machine tool inserts. ③ The high temperature of the mold base is mainly due to the pin overheating caused by the continuous long-term hardware mold of the same mold.

Sheet metal materials corresponding to the processing technology and accuracy standards:

1. Sheet metal (carbon steel/cold rolled sheet/hot rolled sheet/SPCC) materials are suitable for batch OEM precision CNC sheet metal processing. Precision CNC sheet metal processing generally uses CNC machining centers (CNC milling, CNC straightening), CNC lathes and other equipment, and surface treatment using

This is a precision CNC sheet metal processing process, such as hot dip galvanizing, cold dip galvanizing, galvanizing coloring, powder coating, etc.. Curvature: 0-+/-0.1mm.

2. Stainless steel (201, 304, 316) is usually made by laser cutting machine, drilling machine and other equipment for precision CNC sheet metal processing. Surface treatments include sandblasting, anodizing, coloring, blackening, polishing and brushing. CNC machining is 0-+/-0.1mm.

3. In general, precision CNC sheet metal processing of aluminum and steel is done with bending machines, presses, punching machines, welding machines and other equipment. Laser cutting pipe, laser cutting plate, bending, welding, stamping and other processing methods, laser cutting 0-+/-0.1mm.
