The selection function that should be considered when purchasing CNC machine tools

When purchasing CNC machine tools, the selection principle is: comprehensive configuration, give full play to the maximum potential of the host, and consider the benefits in the near future. The selection function of the numerical control system should be practical, not necessarily too much, especially the equipment incorporated into the mass production line should be as simple as possible. For the multi-variety and small-batch production methods, the selection of programming functions should be strengthened, such as Random programming (background programming), motion graphics display, human-machine dialog programming (GPS), macro programming, etc., although the speed of programming can be accelerated, but the cost should be increased accordingly. Another configuration scheme is to simplify the function of programming the CNC system. The automatic programming machine and the communication interface with the CNC system are separately configured. The program processing is done in advance on the programming machine, and then takes a few minutes to be sent to the CNC system. This will further increase the machine start rate.

Many accessories have been developed in improving the processing quality and work reliability, such as automatic measuring devices, contact probes and corresponding measuring software, tool length and wear detection, machine tool thermal deformation compensation software and other accessories. These accessories are selected to require work. Reliable, not one-sided pursuit of novelty. For some auxiliary function accessories, such as cooling, protection and chip removal, the equipment is mainly determined according to the requirements of the field use and process requirements in the future. For example, considering the requirements for processing large-size cast iron parts in the future, it is necessary to use a high-sealing protective cover and a large Flow shower cooling method, paper coolant filter device, etc. In short, choose accessories that are compatible with production capacity.

As a high-tech product, CNC machine tools contain multi-disciplinary professional content. It is not enough to apply and repair the complex technical equipment. The application unit itself is not enough, and it is difficult to do. Rely on and utilize the professional team in society. Therefore, when purchasing equipment, you should also consider the purchase of pre-sales and after-sales technical services around the equipment. The purpose is to make the equipment work as soon as possible.

For some new CNC machine users, the most difficult thing is not the lack of funds to buy equipment, but the lack of a high-quality technical team, so new users from the beginning of the selection of equipment, including the subsequent equipment arrival and acceptance, equipment Manpower and technical support are required for operations, programming, mechanical and electrical maintenance. It is very difficult for these conditions to be solved by users in a short period of time. At present, various machine tool manufacturers have generally paid attention to pre-sales and after-sales services of products, assisting users in process analysis of typical workpieces, performing process feasibility tests and undertaking complete sets of technology. Services, including process equipment development, programming, installation and commissioning, trial cutting of the workpiece, until the full production into production, quickly respond to warranty services, for the user to hold various types of technical personnel training.

In short, CNC machines can be used reasonably in enterprises that attach importance to the construction of technical teams and attach importance to the improvement of the quality of employees. Therefore, when selecting a machine tool, it is recommended that users spend a portion of the funds to purchase technical services for their own shortages, so that the equipment can function as soon as possible.
