In the production process of a press brake, several factors can affect the precision of the product. These include:

1. Mechanical Precision of the Press Brake:

   • Machine Rigidity: The rigidity of the press brake directly affects its processing accuracy. If the machine body isn’t rigid enough, it may deform during the bending process, impacting the final product’s precision.

   • Guide System: The precision of the press brake’s guide system also plays a significant role. If the guides are misaligned or worn out, it can lead to positioning errors, affecting accuracy.

   • Hydraulic System Stability: Variations in pressure or oil temperature in the hydraulic system can affect the bending force’s stability, influencing the bending precision.

2. Die Precision:

   • Die Manufacturing Precision: The accuracy of the die manufacturing directly affects the forming process. If the die surface has defects, wear, or manufacturing errors, the product’s bending precision will be compromised.

   • Die Installation Accuracy: Proper die installation is also essential. If the die isn’t aligned correctly, the bending effect will be inaccurate.

3. Material Properties:

   • Material Thickness and Hardness: Materials with different thicknesses and hardness levels require varying bending forces and precision. Harder materials can cause uneven deformation during bending, leading to precision deviations.

   • Material Yield Strength: The yield strength of the material impacts the required bending force, which can affect bending precision.

4. Operator Skills:

   • Operator Experience and Skill Level: The operator’s familiarity with the press brake, equipment adjustments, and technical proficiency affects the final product’s precision. Inexperienced operators may make mistakes that lead to imprecise bends.

5. Press Brake Parameter Settings:

   • Bending Angle and Die Gap Settings: Incorrect settings of the bending angle or die gap can result in inaccurate product dimensions. For example, if the bending angle is too large or too small, it will affect the product’s appearance and size.

   • Bending Speed and Pressure: Improper bending speed or pressure can lead to uneven bending, resulting in precision issues.

6. Temperature and Environmental Conditions:

   • Temperature Fluctuations: Changes in temperature affect the properties of metals. During heating and cooling, temperature changes can cause deformation in the bending process.

   • Environmental Humidity and Weather Conditions: High humidity or excessively dry conditions can impact machine precision and material properties, affecting the bending accuracy.

7. Maintenance and Care of the Press Brake:

   • Equipment Wear: Over time, parts like bearings, guides, and the hydraulic system may wear out. This wear can degrade machine precision. As wear progresses, accuracy will decrease.

   • Regular Maintenance: Regular maintenance and lubrication of the press brake are essential. Neglecting to clean and maintain the equipment can lead to aging and a decline in precision.

8. Calibration and Inspection:

   • Machine Calibration: The press brake needs to be calibrated regularly to ensure all parameters are within specification. Improper calibration can directly affect bending precision.

In conclusion, several factors affect the precision of press brake products. It’s important to consider mechanical precision, operator skill, die accuracy, material properties, environmental conditions, and more to ensure product accuracy and quality.
