When purchasing CNC machine tools, the selection principle is: comprehensive configuration, giving full play to the maximum potential of the host machine, and 

comprehensive consideration of long-term and short-term benefits. The selection of functions for the CNC system should be based on practicality, and it is not necessary to 

choose too many. Especially the equipment incorporated into the batch production line should be as simple as possible. For machine tools with multiple varieties and small 

batch production methods, the selection of programming functions should be strengthened, such as Although random programming (background programming), motion 

graphics display, human-machine dialogue programming (GPS), macro programming, etc. can speed up programming, the cost will also increase accordingly. Another 

configuration solution is to simplify the configuration of the programming function of the CNC system, and separately configure the automatic programming machine and 

the communication interface with the CNC system. The program processing is completed on the programming machine in advance, and then it takes a few minutes to send it 

to the CNC system. , which can further improve the machine tool operating rate. Many accessories have also been developed to improve processing quality and work 

reliability, such as automatic measuring devices, contact probes and corresponding measurement software, tool length and wear detection, machine tool thermal 

deformation compensation software and other accessories. The principle for selecting these accessories is to require work Be reliable and do not pursue novelty one-sidedly. 

Some auxiliary functional accessories, such as cooling, protection and chip removal devices, are mainly determined according to future on-site use requirements and process 

requirements. For example, considering the requirements for processing large margin cast iron parts in the future, high sealing protective covers, large Flow shower cooling 

method, paper coolant filter device, etc. In short, it is necessary to choose accessories that are suitable for production capacity.

As a high-tech product, CNC machine tools contain multi-disciplinary professional content. For such complex technical equipment, it is not enough to rely on the application 

unit's own efforts to apply and maintain it well, and it is also very difficult to achieve. It must be Rely on and utilize the professional team in society. Therefore, when 

purchasing equipment, you should also comprehensively consider the pre-sales and after-sales technical services surrounding the equipment. The purpose is to make the 

equipment function as quickly as possible.

For some new CNC machine tool users, the most difficult thing is not the lack of funds to purchase equipment, but the lack of a high-quality technical team. Therefore, from 

the beginning of the new user's selection of equipment, including the subsequent equipment arrival, installation and acceptance, equipment Operations, programming, 

mechanical and electrical maintenance, etc. all require talent and technical support. It is very difficult for users to solve these conditions in a short period of time. At present, 

various machine tool manufacturers have generally attached great importance to pre-sales and after-sales services of products, assisting users in process analysis of typical 

workpieces, conducting processing feasibility process tests, and undertaking complete sets of technologies. Services include process equipment development, programming, 

installation and debugging, trial cutting of workpieces, rapid response to warranty services after full production, and various technical personnel training for users.

In short, any enterprise that attaches great importance to the construction of technical teams and the improvement of the quality of employees can use CNC machine tools 

reasonably. Therefore, when choosing machine tools, it is recommended that users spend part of their funds to purchase technical services that are in short supply so that 

the equipment can function as quickly as possible.
