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 .

Process Analysis of CNC Machining Parts Drawing

Process Analysis of CNC Machining Parts Drawing

 

(1) The method of dimensioning in the drawings of CNC machining parts

 

The size on the part drawing is an important basis for manufacturing and inspecting parts. In the production (Produce), the size of the part drawing is required to be free of any errors. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, laser cutting china, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In addition to correct, complete, and clear requirements for marking the size on the part drawing, rationality should also be considered. It should not only meet the design requirements, but also facilitate processing and measurement. ? Regarding dimensioning, it mainly includes functional dimensions, non-functional dimensions, nominal dimensions, basic dimensions, reference dimensions, repeat dimensions, and so on. The dimensions marked on the part drawing are complete and correct, making it easy for the processor to analyze, measure, and process. According to these dimensional accuracy (accuracy), the blank is determined to be Φ95*250mm and the material is 45 steel.

 

(2), analyze (Analyse) the geometric elements of the contour of the CNC machining aluminum parts

 

The contour of the part is mainly composed of cylindrical surface, spherical surface, groove (gōucáo), keyway, inner hole and so on. CNC machining is a process method for parts processing on CNC machine tools. The process regulations of CNC machine tool processing and traditional machine tool processing are generally the same, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batches, complex shapes, and high precision, and to achieve high-efficiency and automated processing.

 

(3) Analyse the structure and craftsmanship of CNC machining parts

 

The part is a slender shaft. The slender shaft has the characteristics of small diameter and too long length. The length of the suspension body is too long when processed, and it is easy to vibrate the knife or the surface roughness value of the processing is too low, so it must be used for processing. Auxiliary tool holder and auxiliary fixture. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, metal forging and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. There is also something to pay attention to during heat treatment, because it will deform after being hardened by cold work, resulting in a bowing or S-shape.

 

(4) Analyse the precision (precision) and technical requirements of CNC machining parts

 

The precision (precision) and various technical requirements of this part are complete and reasonable

The CNC machining precision (precision) in this process is required to be high. This requirement can be met in the CNC machine tool (attribute: automated machine tool). The machining is divided into three types: rough machining, semi-finishing and finishing. The procedure is carried out.

. The left end of the outer circle size of Φ90 in the figure has higher position accuracy (precision) requirements. All procedures in this section should be completed in one clamping process, except for the keyway.

. For surfaces that require high surface roughness, the circumferential constant linear speed should be used for cutting.
