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
