The molten metal was not directly poured into the mold cavity due to the possible corrosion of the mold in Dongguan CNC plant. The molten metal is poured into a gate cup with storage function and smoothly enters into the sprue. The gate cup also has the ability to prevent the slag from entering t...

As the most common and commonly used feature of mechanical parts, holes in Guangdong machining plant play different roles and uses, such as positioning holes, datum holes, assembly holes, process holes, etc. the accuracy and requirements of holes are also very different. With the application of a...

3、 Selection of processing method and determination of processing scheme （1） Selection of processing method The selection principle of machining method in Dongguan CNC machining plant is to ensure the machining accuracy and surface roughness of the machined surface. Because there are many process...

The selection of cold stamping materials in Guangdong mechanical processing plant affects that the cold stamping materials should meet the design requirements and stamping process requirements of the parts, otherwise it is easy to damage the mold and reduce the service life of the mold. The surfa...

The service life of cold stamping die in Dongguan CNC processing factory is calculated by the number of workpiece produced. There are many factors that affect the life of cold die. The main factors are the design of die structure, the materials of punch and die used in the manufacturing of die, t...

1. causes of residual stress a. When cutting in Dongguan CNC processing plant, plastic deformation occurs in the surface metal layer, which makes the specific capacity of surface metal increase. Because plastic deformation only occurs in the surface metal, the specific capacity of the surface met...

（1） Factors affecting surface roughness in machining 1. Dongguan CNC processing factory considers that the re mapping of tool geometry: when the tool moves with respect to the workpiece, the residual area of cutting layer is left on the machining surface, and the shape of the tool geometry is ref...

The corrosion resistance of the parts in Dongguan CNC factory depends on the surface roughness to a great extent. The larger the surface roughness is, the more corrosive substances will accumulate in the valley. The worse the corrosion resistance. The residual tensile stress in the surface layer ...

1> Guangdong machining factory teaches you what's the secret of sharpening, how to sharpen high speed steel ladder thread turning tool? Thread turning mainly more hands-on, more with the teacher Fu learn, so as to progress quickly. Thread is a continuous protrusion with specified tooth profile fo...
