The PLC axis control realizes that the main shaft and the tool post control share a group, and the two sets of gear ratio transmission;
PLC realizes the normal tool change of OMG turret in Italy, and needs to solve the problem of inconsistent tool tips when the boring tool is retracted in the parity sleeve when Siemens used the turret.
The PLC realizes the safety judgment of the truss loading and unloading conditions, and connects the external truss control system in real time to realize the truss loading and unloading;
To ensure the accuracy of the machine tool, to realize the machining of crankshaft flange holes, to replace Siemens machine tools with the same process.



solution

The two-channel X, Z, Y, and C axes use a 17-bit absolute encoder servo motor, and the two-channel spindles use a spindle motor with an incremental 5000-line encoder;
Both channels X and Y axes use HEIDENHAIN LC185 encoders as feedback devices to effectively improve the accuracy of the machine tool;
Write the ladder diagram to realize the control logic of the Italian OMG turret, set the boring tool number, and perform parity detection on its tool number. When the target tool number is a boring tool, it is conditional to determine whether the spindle is reversing when the turret is released, which solves the problem of inconsistent tool tip directions when the boring tool is retracted;
Compile ladder diagram to realize automatic loading and unloading of external trusses safely and efficiently.





Application effect

Axial / radial turning, drilling, boring, milling, tapping, etc .;
The system's PLC axis control implements its tool change logic, which effectively solves the problem of inconsistent tool tip orientation when the boring tool is withdrawn;
The flexible application of truss automatic loading and unloading, synchronization / overlap / mixing control between paths, M waiting and other functions make the processing cooperation of the two channels more integrated, effectively improve the processing efficiency, and can completely replace the Siemens system for the same process.
