Information

The numerical control process originates from the general processing technology, and is an organic combination of general processing technology, computer numerical control technology, computer-aided design and auxiliary manufacturing technology. With the continuous development of technology, more and more parts need to be precisely machined in modern manufacturing, and the requirements for machining accuracy and workpiece surface complexity are also getting higher and higher. Therefore, CNC machining has received a lot of attention, but in terms of cost reduction, CNC machining is more expensive than traditional machining . Now , let's take a closer look at the difference between CNC machining and traditional machining processes.

1. Machining technology

The General Machine PROCESS Can Simplify Positioning Standards, Clamping Methods, Tools, Cutting Methods, ETC., But the Data Processing Process is related y complicate , so the factors must be fully consider. The process can have multiple schemes. Multiple processing parts and processing tools can be processed into a main line, and the process has various characteristics.

2. Clamping and fixing device

The NC Machine PROCESS Not only needs to relateds fix the coordinate direction of the fixture and the machine too , but also needed the dimensional reluctorius ATIONSHIP BETWEEN The Part and the Machine Tool Coordinal System. FURTHERMOR steps are efficiently controlled. In addition, in the traditional processing process, the processing capacity of the machine itself is limited, so multiple clamping is required during the processing. In addition, due to the use of specialized fixtures, fixture design and manufacturing cost s are higher, and product production costs will actually increase.CNC machining process positioning can be debugged with instruments, and in most cases, no special fixtures need to be designed, so the cost is relatively low.

3. Knives.

The choice of tools in the machining process depends on the machining process and processing method. Especially in CNC processing, the use of high-speed cutting not only helps to improve processing efficiency, but also ensures processing quality, thereby effectively reducing the probability of cutting deformation and shortening the processing cycle, so the demand for cutting tools is greater.

There is currently another dry cutting method. This cutting method does not use cutting fluid for cutting, or only adds a small amount of cutting fluid for cutting, so it has good heat resistance. Compared with the conventional machining process, the CNC machining process puts forward higher requirements on the performance of the cutting tool.

How about machining? Does the machining factory make money?

First, from the perspective of the general environment, the poor economic conditions at home and abroad in the past two years have had a great impact on basic industries, especially the infrastructure and automobile industries.

Secondly, from the perspective of data, the domestic steel price is the lowest in the past 10 years, the scrap iron scrap price is more than half of the previous one and can only be sold at 1200/ton, and the factory lease price is also the lowest in the industrial zone in recent years. The factory rent has not exceeded 12 /, news of factory closures is also frequently reported.

Third, the cost recovery time is getting longer and longer. Even if life is not good at first, as long as the equipment does not stop, the initial equipment cost can be recovered for a year and a half, and now it occupies a large part in the distant future.
