Shandong CNC lathe servo system basic requirements
1. High-precision CNC machine tools cannot be adjusted and compensated for various errors by manual operation like traditional machine tools, so it requires high positioning accuracy and repeated positioning accuracy.
2, fast response characteristics, fast response is one of the signs of the dynamic quality of the servo system. It requires the servo system to follow the command signal not only to follow the error, but also to respond quickly and with good stability. After the system is given input, it can reach a new balance after a short adjustment or can quickly restore the original balance under the influence of external disturbances.
3, the speed range is large Because the workpiece material, tool and processing requirements are different, to ensure that the CNC machine tool can get the best cutting conditions under any circumstances, the servo system must have sufficient speed range, which can meet the high speed Processing requirements, but also meet the requirements of low-speed feed. Moreover, there is a large torque output at low speed cutting.
4, good system reliability Because the use rate of CNC machine tools is very high, often 24h continuous work can not stop, so the servo system is required to work reliably.
