How to choose a CNC system

The functional applicability of the CNC system is undoubtedly an important limiting factor for the design and selection of CNC machine tools.The following factors are important factors that must be considered in the selection of CNC systems.
(1) Driving ability
The power range of the servo and the range of supporting motors in the solutions of different CNC suppliers are also different.First of all, it should be preliminarily screened from the matching motor type and power range.In particular, it is necessary to pay attention to whether the CNC machine tool scheme includes torque motors, linear motors, electric spindles, synchronous electric spindles or asynchronous electric spindles, the rated current requirements and overload current requirements of the above-mentioned motors, the maximum speed requirements of the electric spindle, etc.
(2) Fully closed-loop requirements and dual-drive requirements
Most CNC machine tools, especially large and heavy-duty CNC machine tools, have fully closed-loop and dual-drive requirements.In the fully closed-loop control scheme, it is necessary to choose between distance-coded gratings, absolute-value gratings, and ordinary incremental gratings, and the CNC system must also support the corresponding feedback signal access.
(3) Five-axis control requirements
Five-axis machine tools need to clarify whether five-axis linkage or only five-sided machining is required, and the corresponding selection of CNC system functions is also different.For example, for the processing of five-sided boxes, RTCP is usually not required, and the choice is relatively large.At the same time, for the five-axis function that may involve CNC system suppliers, export licenses, after-sales service, technical support, etc. must also be seriously considered.
(4) Production system requirements
The networked support of CNC systems has become a necessary condition for the integration of production systems.For CNC machine tools to be included in 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 connected to the advanced CNC system built-in OPC server, and the internal data of the CNC system is opened to users in accordance with the OPC standard.In addition, for production systems, automated online workpiece inspection and tool inspection are also functions that must be supported.
