GSK988TD on dual-channel turning and milling composite horizontal CNC machining center

Ensure the accuracy of the machine tool, realize the machining of the crankshaft flange hole, and replace the Siemens same-process machine tool.

The PLC axis control realizes that the main shaft and the tool post control share one group, and the two sets of gear ratios are driven;

PLC realizes the normal tool change of the OMG turret in Italy, and needs to solve the problem that the retracting tool tip of the boring tool is inconsistent when the knives are matched with the turret in the past;

The PLC realizes the safety judgment of the loading and unloading conditions of the truss, and the external truss control system is connected in real time to realize the loading and unloading of the truss.

solution

The two-channel X, Z, Y, and C axes are all servo motors with 17-bit absolute encoders, and the two-channel spindles are all spindle motors with incremental 5000-line encoders.

The HEIDENHAIN LC185 scale is used as a feedback device for both the X and Y axes, which effectively improves the accuracy of the machine.

Write the ladder diagram to realize the control logic of the Italian OMG turret, set the boring tool number, and perform the parity detection on the tool number. When the target tool number is the file, when the turret is loosened, the spindle is reversing for condition judgment, which solves the problem that the tool tip direction is inconsistent when the boring tool retracts;

The ladder diagram is written to realize the safe and efficient automatic loading and unloading of the external truss.

Application effect

Achieve shaft/radial turning, drilling, boring, milling, tapping and other composite machining;

The system PLC axis control realizes its tool change logic, which effectively solves the problem that the tool tip direction is inconsistent when the tool is retracted.

The truss automatic loading and unloading, the inter-path synchronization/overlap/hybrid control, and the flexible application of M waiting function make the two-channel machining cooperation more integrated, effectively improve the processing efficiency, and can completely replace the Siemens system for the same process.
