数控行星架偏心孔超精机
CNC planet carrier bore superfinishing machine
主要用途Main Purposes
本系列超精机主要用于超精行星架的内孔一 3孔均布分配或者多孔不均布分配。
The series of superfinishing machine are mainly used for finishing the planet carrier bore—3 bores or more.
主要结构与特点 Main Structures and Features
1、SIM ENS (或FAN UC)全数宇交流伺服控制系统
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.
