龙门刨床是一种广泛使用的金属切削加工机床,是许多大型企业不可缺少的设备,在工业生产中占有重要的位置。龙门刨床工作台的行程控制多采用传统的继电器、行程开关控制方式来实现,该方式存在着故障率高、接线复杂、灵活性小、检修不方便等缺点。这对加工性能及成本有很大的影响,有的甚至无法在一些加工要求稍高的工件场合下使用。PLC和变频调速技术经过多年的推广和使用,各项性能和技术指标不断趋于完善和成熟,节能效果显著。为提高龙门刨床的加工精度和生产效率,采用PLC和变频器对龙门刨床电气主拖动系统进行改造,已成必然趋势。
Planer is a widely used metal cutting machine tool, is an indispensable device for many large enterprises, occupies an important position in industrial production. Planer table travel control using more traditional relay, travel switch control method to achieve this method there is a high failure rate, wiring complexity, flexibility, inconvenience and other shortcomings. This has a great influence on the processing performance and cost, and some can not even be used in some workpieces with slightly higher processing requirements. PLC and frequency control technology after years of promotion and use of various performance and technical indicators continue to improve and mature, significant energy-saving effect. In order to improve the processing precision and production efficiency of the planer planer, adopting PLC and frequency converter to transform the main planer electric system of the planer has become an inevitable trend.
