Product Description

CNC machined parts From China Manufacturers and Suppliers


Engaged in mechanical processing, high-precision manufacturing of mechanical parts and determination of blank selection, not only affect the economy of blank manufacturing, but also affect the economy of mechanical processing. Therefore, when determining the blank, CNC machined parts is necessary to consider not only the hot processing factors, but also the economic factors, as well as the requirements of cold processing, so as to reduce the manufacturing cost of the parts in the process of determining the blank.

 

I. casting: the casting method should be used to manufacture the rough parts with complex shapes. At present, most castings are made by sand mold, which is divided into wood mold manual modeling and metal mold machine modeling. CNC machined parts is suitable for small batch production or large parts casting. The metal mold machine has high molding productivity and casting precision, but the cost of equipment is high, and the weight of castings is limited, so it is suitable for large-scale production of small and medium-sized castings. Secondly, a small number of small castings with high quality requirements can adopt special casting, such as pressure casting, centrifugal manufacturing and investment casting.

 

2. Forgings: steel parts with high mechanical strength requirements generally need forging blanks. There are two kinds of Forgings: free forging and die forging. The free forging forging can be obtained by hand forging (small blank), mechanical hammer forging (medium blank) or press forging (large blank). This kind of forging has the advantages of low precision, low productivity, large machining allowance and simple structure, which is suitable for single piece and small batch production, as well as manufacturing large forgings.

 

The accuracy and surface quality of die forgings are better than that of free forgings, and the shape of forgings can be more complex, so the machining allowance can be reduced. The production efficiency of die forging is much higher than that of free forging, but it needs special equipment and forging die, so it is suitable for large batch of medium and small forgings.
