在对T68镗床的基本结构和控制要求进行分析后,选择了西门子公司的S7-200系列PLC,取代了原继电器-接触器控制电路,完成了控制系统的技术改造,经过调试满足实际生产要求。经过改造后的镗床控制系统硬件电路得到了简化,提高了机床工作的可靠性。
After analyzing the basic structure and control requirements of T68 boring machine, Siemens S7-200 series PLC was chosen to replace the original relay-contactor control circuit, and the technical transformation of the control system was completed. After debugging, the actual production requirements were met. After the transformation of the boring machine control system hardware circuit has been simplified to improve the reliability of machine tools.
