What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

What are the requirements for the division of CNC machining processes?

When Cnc Machining processes are divided, it must be flexibly controlled based on the structure and manufacturability of the parts, the functions of the CNC machining center machine tools, the number of parts CNC machining content, the number of installations and the production organization of the unit. It is also recommended to adopt the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but must strive to be reasonable. The division of processes can generally be carried out according to the following methods:

 

When CNC machining is divided into processes, it must be flexibly controlled according to the structure and manufacturability of the parts, the functions of the CNC machining center machine tools, the number of parts CNC machining content, the number of installations and the production organization of the unit. It is also recommended to adopt the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but must strive to be reasonable. The division of processes can generally be carried out according to the following methods:

 

1. Tool centralized sorting method.

 

This method is to divide the process according to the tool used, and use the same tool to process all the parts that can be completed on the part. In order to reduce the tool change time, compress the idle time, and reduce unnecessary positioning errors, the parts can be processed according to the method of tool concentration, that is, in one clamping, use one tool to process all the parts that may be processed as much as possible, and then Change another knife to process other parts. This can reduce the number of tool changes during the plasctic machining, reduce idle time, and reduce unnecessary positioning errors.

 

2, the order of processing parts.

 

The structure and shape of each part are different, and the technical requirements of each surface are also different. Therefore, the positioning methods are different during processing, so the process can be divided according to the different positioning methods.

 

For parts with a lot of processing content, the processing part can be divided into several parts according to its structural characteristics, such as inner shape, shape, curved surface or plane, etc. Generally, the plane and positioning surface are processed first, and then the hole is processed; the simple geometric shape is processed first, and then the complex geometric shape is processed; the parts with lower precision are processed first, and then the parts with higher precision requirements are processed.

 

3, the roughing and finishing are sorted in order.

 

When dividing the process according to factors such as the machining accuracy, rigidity and deformation of the part, the process can be divided according to the principle of separating rough and finishing, that is, roughing and then finishing. At this time, different machine tools or different tools can be used for processing; For parts that are prone to deformation during CNC machining, due to the deformation that may occur after rough machining, it needs to be corrected. Therefore, in general, all the rough and finishing processes must be separated.
