Advantages of CNC machine tool processing

CNC machine tool (attribute: automatic machine tool) processing is a high-precision, high-efficiency automatic machine tool. The use of CNC machine tool processing can improve processing efficiency, create more value, and get rid of the backward processing technology. The processing technology of ordinary lathes is similar. What are the advantages of CNC machining?

 

1. High productivity

 

CNC machine tools can effectively reduce the processing time and auxiliary time of the parts. The spindle speed and feed range of the CNC coffee machine parts tools are large, allowing the machine tools to carry out powerful cutting with large amounts of cutting, the rapid movement and positioning of the moving parts of the CNC machine tools and high-speed cutting processing. , It reduces the turnaround time between processes of semi-finished products and improves production efficiency.

 

2. High processing accuracy

 

The machining accuracy (precision) of CNC machine tools can generally reach 0.0050.1mm. CNC machine tools are controlled in the form of digital signals. Each time the CNC device outputs a pulse signal, the moving parts of the machine tool move by one pulse equivalent (generally 0.001mm) , And the average error of the backlash of the machine tool's feed drive chain and the lead screw pitch can be compensated by the numerical control device. Therefore, the numerical control machine tool has a relatively high positioning accuracy. CNC machining CNC is also called computer gong, CNCCH or numerical control machine tool. It is actually a kind of name in Hong Kong, which greatly reduces the number of tooling. CNC machining parts with complex shapes does not require complex tooling. CNC machining is a new type of processing technology, the main work It is to compile the processing program, that is, to convert the original manual work to computer programming. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

 

3. Highly flexible

To ensure the surface accuracy (accuracy) of the workpiece, it mainly depends on the processing procedure. It is different from the ordinary machine tool. There is no need to manufacture and replace many tools and fixtures, and there is no need to adjust the machine tool frequently. CNC machining General CNC iot machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring 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. Therefore,  Stainlesss teel parts tools are suitable for occasions where parts are frequently replaced. That is, it is suitable for single piece, small batch production and the development of new products, shortens the production preparation cycle, and saves a lot of process equipment costs.

 

4. The processing quality is stable and reliable

 

To process the same batch of parts, on the same machine tool, under the same processing conditions, using the same tool and processing procedure, the cutting path of the tool is exactly the same, the consistency of the masks machine parts is good, and the quality is stable (explanation: stable and stable; no change).

 

5. Conducive to modernization of production management

 

CNC machine tools (attributes: automated machine tools) can accurately estimate the other processing time in advance, and the tools and fixtures used can be standardized and modernized. Numerical control machine tools use digital signals and standard codes as control information, which is easy to realize the standardization of processing information. At present, it has been organically combined with computer-aided design and manufacturing (CAD/CAM), which is the basis of modern integrated manufacturing technology.

 

6. Improve working conditions

 

After the CNC machine tool (attribute: automatic machine tool) is adjusted before processing, enter the program and start it, and the machine tool can automatically and continuously process until the end of the processing. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and letters, and the processing required by the processing technology. It generally refers to the process of machinery parts on CNC machine tools.

 

In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. Operators are mainly engaged in program input, editing, loading and unloading of masks-machine-parts, tool preparation, observation of aluminum machining status, and parts inspection. The labor intensity is greatly reduced, and the labor of machine tool operators tends to be intellectual work. In addition, the machine tool is generally closed processing, which is clean and safe.
