CNC Machining

CNC Machining is directly changing the size, shape, mutual position, surface roughness or properties of raw materials or semi-finished products to make them into finished products. 


Including: casting, welding, electroplating, heat treatment, machining and assembly processes.

The process of removing the surface material of the part by metal cutting, the process of obtaining the finished product is called a machining process.

CNC Precision Machining

Generally speaking, a machining process normally refers to the process of removing the surface material of the part and obtaining the finished product. However, in order to obtain a well-refined product, people were used to take many steps and the whole process could take a relatively long time. Whereas, as the CNC precision machining eventually made its entrance into the industry, this situation has been greatly improved.


Capable of performing a variety of processes like casting, welding, electroplating, heat treatment, machining, and assembly, CNC precision machining can directly change the size, shape, position, surface roughness and other properties of raw or semi-finished materials and transfer them all into well-finished and refined final products. Therefore, having solved the problems of complex, precise, small batch, and multi-variety parts processing, CNC precision machining, or the so-called CNC precision milling, has now gradually become an important part in metal processing. And as a professional CNC precision machining factory, EMP Tech can provide you with the best aluminum CNC service in China.


The Basic Working Process Route for CNC Precision Machining

Processing the reference surface

when the raw material is placed for the process of machining and manufacturing services, the surface of the material should be processed first so as to provide a fine reference for the processing of the subsequent process.


Dividing the processing stage

The processing of a high-quality surface with precision CNC milling can normally be divided into 3 processing stages: roughing, semi-finishing and finishing. With the setting of these processing stages, the CNC turning & milling can then be conducted precisely and clearly. 


Dividing the Processing Stages   Machining the Finished Holes


Machining the plane-finished holes

As for the production of precise and small aluminum parts, such as brackets and connecting rods, the plane-finished holes has to be firstly machined by the CNC machine. By doing so, these firstly machined holes can then perform effectively as accurate references for the positioning of the following steps. 


The finishing of the main surface (such as grinding, fine grinding, rolling, etc.) should be carried out in the final stage of the process. And it should be noted that during this stage, the processed parts should be treated carefully as any slight collision can damage the surface.

The Advantages of CNC Precision Machining

  • As for CNC machines, they have strong adaptability in terms of processing objects. They can provide suitable processing methods for various mold manufacturing.


  • CNC milling service also has the characteristics of high processing precision and stable processing quality.


  • Since precision CNC machining is controlled by computers, multi-coordinate linkage can be easily carried out by CNC machines, and parts with complex shapes can also be processed.


  • CNC programming services also possess the quality of high flexibility. When the design of the custom CNC aluminum parts are changed, people will only need to change the NC program in the CNC machine and the whole machining process will be changed accordingly.


  • Since the machine tool is highly automated, labor intensity can then be greatly reduced.


  • Conducive to the modernization of production management, CNC machine tools use digital information and standard codes to process, transmit information, and use computer control methods to replace the foundation for the integration of computer-aided design, manufacturing and management.


The Possible Application of CNC Precision Machining

  • The production of small batch parts and custom CNC aluminum


  • The production of aluminium parts that need to be modified multiple times


  • The production of working parts with high machining accuracy requirements


  • The production of expensive parts, which can cost huge economic losses once they are scrapped
