solution

 

The system uses 0.1u precision parameters, two channels each add a CS axis, set the polar coordinate interpolation related parameters;

The spindle drive and motor adopt GS3100Y-LP2-ZJY265-11BM-B3 (A1) to match the spindle feedback device ERA180 9000 line (Heidenhagen encoder), which improves the spindle resolution and increases the precision of the spindle participating in polar coordinate interpolation

Feed X-axis drive and motor adopt GS2075T-LA1-130SJT-MZ150D (A4I) matching method grating ruler GSX-240-5 (FAGOR), feed Z-axis drive and motor adopt GS2075T-LA1-130SJT-MZ150D (A4I) Matching the standard grating ruler GSX-740-5 (FAGOR) greatly improves the feedback accuracy of the feed axis;

According to the code of the Italian 12-position servo power turret, the ladder diagram increases the control logic of the turret.

 

 

 

Application effect

 

The flexible application of dual-channel dual-spindle docking enables the workpiece to complete the processing requirements of each process in one clamping, which greatly reduces the clamping error, and the application of high-resolution encoders and grating scales greatly improves the machine tool. Precision, thereby ensuring the processing quality of the workpiece;

The application of the system PLC axis control instruction AXCTL simplifies more peripheral auxiliary logic programming in the past and makes the control logic part of the turret more concise;

The increasing application market of non-standard special machines for machine tools will inevitably allow the system functions to develop in a diversified direction.
