Troubleshooting Solutions
In precision sheet metal fabrication, the Y1/Y2 axis control system of CNC press brakes serves as the core element ensuring bending accuracy. This dual-axis synchronous system intelligently coordinates the movement of both hydraulic cylinders, effectively resolving deflection issues common in traditional single-axis systems.
I. Technological Innovation Principles
Modern high-end press brakes utilize a dual-axis control system featuring:
High-precision grating scale feedback (resolution: 0.001mm)
Dual servo motor closed-loop control
Real-time pressure compensation algorithms
Automatic deflection correction function
II. Standard Operating Procedures
Startup Calibration
After prolonged shutdown, execute:
Dual-axis auto-zeroing program
Hydraulic system pre-pressure test
Laser alignment detection (error ≤0.02mm)
Runtime Monitoring
Dual-axis position comparison at 10ms intervals
Dynamic pressure balance adjustment
Abnormal vibration monitoring and alarm
Maintenance Essentials
Weekly hydraulic oil cleanliness inspection
Monthly grating scale calibration
Quarterly servo motor filter replacement
III. Common Issue Resolution
| Symptom | Possible Cause | Solution |
| Uneven bending angles | Grating scale contamination | Clean with anhydrous ethanol |
| Cylinder sync alarm | Servo valve blockage | Execute forced flushing procedure |
| Positioning drift | Encoder interference | Verify grounding resistance <4Ω |
