What are the factors to consider when choosing a CNC system?

If in the selection process, there is a factor that is not selected accurately, then it will definitely directly affect the final product effect, so when choosing each one must be carefully selected, and the functional applicability of the CNC system is selected for CNC. The design and selection of machine tools is undoubtedly an important restrictive factor. The first thing to consider is its drive capability. The power range of the servo and the range of the supporting motor in the solutions of different CNC suppliers are also different.

First of all, we should make a preliminary selection from the matching motor type and power range. In particular, pay attention to whether the CNC machine tool plan includes torque motors, linear motors, and electric spindles are synchronous electric spindles or asynchronous electric spindles, the rated current requirements and overload current requirements of the above motors, and the speed requirements of the electric spindle.

A five-axis machine tool needs to be clear whether five-axis linkage or only five-sided machining is required, and the corresponding selection of the CNC system functions is also different. For example, for the processing of five-sided cabinets, RTCP is usually not required, and the choice is relatively large. At the same time, the export license, after-sales service, etc. must also be carefully considered by the supplier of the CNC system for the five-axis function.

Most of the CNC machine tools introduced by the mechanical processing plant, especially the large and heavy CNC machine tools, have full closed loop and dual drive requirements. In the full-closed-loop control scheme, it is necessary to choose between distance-coded grating and ordinary incremental grating, and the numerical control system should also support the corresponding feedback signal access.

The networked support of the CNC system has become a necessary condition for the integration of the production system. For CNC machine tools that are to be incorporated into a highly automated production system, it must be clear that the CNC system has corresponding access solutions, including low-level PLC input and output points. Directly connect to the built-in OPC server of the numerical control system, and open the internal data of the numerical control system to users in accordance with the OPC standard; in addition, for the production system, automatic online workpiece detection and tool detection are also functions that must be supported.
