Importance and operation guide of adjusting the level of CNC Press Brake

As the core equipment of sheet metal processing, the stability of the bending machine directly determines the quality of product molding. The horizontal adjustment during equipment installation and use is the basic link to ensure its performance. ZYCO will analyze the importance of horizontal adjustment from a technical perspective and provide operation guidelines.

Ⅰ. The impact of horizontality on CNC bending machines

1. Processing accuracy guarantee

Problem phenomenon: If the equipment is not leveled, the deviation of the parallelism between the slider and the workbench will lead to:

- Uneven bending angle of the plate (such as inconsistent angles at both ends)

- Distortion and deformation of long-sized workpieces

Technical principle: When the horizontal error exceeds 0.02mm/m, the compensation ability of the hydraulic system fails, and the error is gradually amplified.

2. Equipment life protection

Mechanical wear: In the non-level state, the guide rail and the slider are unevenly stressed, resulting in:

- Abnormal wear of the single-side guide rail (wear rate increased by 3-5 times)

- Hydraulic cylinder piston rod is overloaded, and the seal is accelerated aging

Economic cost: The maintenance frequency of unleveled equipment increases by more than 30%, and the average annual maintenance cost increases by about 15%-20%.

3. Safety risk control

- Gravity center deviation may cause abnormal vibration of equipment

- High-pressure hydraulic system may cause pipeline leakage due to uneven force

Ⅱ. Horizontal adjustment operation specifications

1. Preparation of detection tools

- High-precision level (recommended 0.02mm/m accuracy)

- Adjustable anchor bolts/washers

- Laser calibrator (for large equipment)

2. Adjustment steps

- Basic detection: clean the equipment base and remove oil and impurities

- Multi-point measurement: measure the horizontality in a "米" shape (at least 8 detection points)

- Dynamic calibration: run the equipment without load to the operating temperature and then retest

- Locking and fixing: adjust the anchor bolts to a horizontal error of ≤0.05mm/m

Ⅲ. Common misunderstandings and solutions

| Misunderstandings | Correct approach |

| "No leveling is required for a flat ground" | Concrete foundation settlement needs to be retested every year |

| "Small workpiece processing can be ignored" | Accumulated errors will cause system parameter distortion |

| "One-time leveling is effective for life" | It is recommended to check every 500 hours or after 10 mold changes |

Ⅳ. Conclusion

The horizontal adjustment of the bending machine is not a simple installation process, but a precision management throughout the entire life cycle of the equipment. ZYCO engineers recommend that users can reduce the scrap rate by 15%-30% and extend the equipment overhaul cycle by 2-3 years by establishing a standardized leveling operation process, thus achieving true lean production.
