Applicability function of CNC system is undoubtedly important factors limiting for design and selection of CNC machine tools. The following factors are important factors that must be taken into account in selecting CNC systems.
The driving ability
In different numerical control supplier solutions, the servo power range and the matching motor range are also different. First of all, a preliminary screening should be done from the type of motor that matches the power range. Special attention should be given to whether the torque motor, linear motor, electric spindle spindle is synchronous or asynchronous electric spindle CNC machine tools including the scheme, the motor rated current and overload current demand, demand the highest speed electric spindle.
The whole closed-loop demand and double drive demand
CNC machine tools, especially large, Heavy CNC machines, most have full closed loop and double drive demand. In the full closed loop control scheme, the choice between the distance encoding grating, the absolute value grating and the conventional increment grating is carried out, and the corresponding feedback signal is also required for the numerical control system.
The five axis control requirements
Five axis machine tools need to be clear whether the five axis linkage or only five processing, the corresponding choice of CNC system function is also different. For example, for the five sides of the box processing, usually do not need RTCP, the choice is relatively large. At the same time, for the five axis function, may involve CNC system suppliers, in the export license, after-sales service, technical support, etc., must also be seriously considered.
The production system requirements
Networked support of CNC system becomes the necessary condition of production system integration. For to be included in the CNC machine tool production system with high automation, must be clear about the NC system with the corresponding access solutions, including PLC input low output by direct access to advanced CNC system built-in OPC server, in accordance with the OPC standard is open to the user data within the NC system. In addition, for the production system, automated online job detection and tool inspection are also functions that must be supported.
