It's very important to choose the right mechanical processing technology and the blank types for CNC machined parts, It will help to save a lot cost with the correct blanks.There are different types of manufacturing methods to for workpieces blanks.They are related to the number of processes, material consumption, and processing labor of cnc-worked parts.We introduce some types of blanks for machining parts.

The types of commonly used cnc workpieces are: castings, forgings, profiles, weldments, stampings, etc., while the same type of blanks may have different manufacturing methods. The choice of blanks should take into account the size of the production, which largely determines the economics of using a certain method of manufacturing blanks. If the scale of production is large, a high-precision and high-yield billet manufacturing method can be used, so that even though the investment is high at one time, the cost of sharing the billet to each billet is small. Moreover, due to the relatively high precision of the blank manufacturing method, the productivity is generally high, which saves raw materials and can significantly reduce the amount of mechanical processing labor. Furthermore, the high precision of the blank can simplify the process and process equipment and reduce the total cost of the product.

The selection of cnc machined blanks should take into account the shape and size of the workpiece structure. For example, the shape of the complex and thin-walled blanks, generally can not be used metal casting; large-size blanks, often can not be used forging, die casting and casting. Another example is that some relatively small parts with special shapes, due to the difficulty in machining, often use more precise methods of manufacturing blanks, such as die-casting, investment casting, etc., to minimize the amount of machining.

The selection of cnc machined blanks should take into account the mechanical properties of the part. The same material uses different methods of manufacturing blanks, and their mechanical properties are often different. For example, metal-formed cast blanks are stronger than sand cast blanks, and centrifugal cast and pressure-cast blanks are stronger than metal cast blanks. Parts with high strength requirements use forgings, and sometimes they can also use ductile iron castings.

The selection of cnc workpiece blanks should be based on the existing equipment and technical level of the plant to consider the possibility and economy. It should also consider the possibility of using new processes, new technologies and new materials, such as precision casting, precision forging, cold rolling, cold extrusion, powder metallurgy and engineering plastics. With these blank manufacturing methods, the amount of mechanical processing can be greatly reduced, and sometimes even machining can no longer be performed, and its economic effect is very significant.
