我厂的C620卧式车床因多年使用加工精度达不到要求。为此,我们采用JWK-5GB单板机数控系统对C620车床进行改造,并取得成功。 1.控制系统的功能及主要参数 JWK-5GB是一种开环的经济型数控系统,它由控制部分、驱动部分和步进电机组成。其步进伺服系统采用高低压电源供电,定电流控制电路,使步进电机高频运行时的输出转矩增大,改善了系统的快速性能,降低了加工零件的表面粗糙度值,具有加工直线、锥度、螺纹和圆弧等功能,其加工精度在±
C620 horizontal lathe of our factory can not meet the requirements due to the precision of machining for many years. To this end, we use JWK-5GB veneer CNC system C620 lathe transformation and success. 1. Control system functions and main parameters JWK-5GB is an open-loop economical CNC system, which consists of the control section, the drive section and the stepper motor. The stepper servo system uses high and low voltage power supply, constant current control circuit, so that the output torque of the stepper motor operating at high frequency increases, improving the system’s fast performance, reducing the surface roughness of the machined parts, with processing Straight line, taper, thread and arc and other functions, the machining accuracy of ±
