数控偏心轴外径超精机
CNC eccentric shaft ribs superfinishing machine
主要用途Main Purposes
本系列主要用于超精偏心轴外径，也可超精同心轴的外径。
This series of superfinsing machine are used to finishing the eccentric shaft rib, single or double ribs.
主要结构与特点 Main Structures and Features
1、SIMENS (或FANUC)全数字交流伺服控制系统
2、大往复小振荡超精方式，大往复由伺服电机驱动，小振荡为变频调速，振幅可调。
3、伺服电机控制油石的大往复，可根据工件加工工艺要求设定油石的运动曲线，保持加工的形状或将工件超精出凸 度。
4、采用单工位两步法超精，粗、精超工步：工件转速、油石压力、振荡频率自动转换。
1、Adopting SIEMENS (or FANUC) all-digital AC servo control system.
2、Adopting a high-precision shaft with sleeve, the motor of workpiece adopts AC frequency variable motor, frequency variable speed.
3、The dramatic reciprocation of the stone is controlled by servo motor. The movement curve of stone can be determined as per the workpiece manufacturing requirements to keep the manufacturing shape and workpiece to be superfinished with crowning.Adopting single-point diamond pen for dressing automatically.
4、Single-stage and two-steps for superfinishing is used. Rough and fine superfinishing processing steps are used in the machine. The revolution of workpiece, stone pressure and oscillation frequency can be automatically transformed.
