4+1-Axis vs 6+1-Axis Press Brakes, which one is better?

Press Brakes

Press brakes are essential machines in the sheet metal fabrication industry. They come in various configurations, with the number of axes indicating the degree of control over the bending process. Two popular types are the 4+1-axis and 6+1-axis press brakes. This article will explore their differences, advantages, and help determine which one might be better suited for various applications.

4+1-Axis Press Brake

 

A 4+1-axis press brake controls the Y-axis (vertical movement of the ram) and two X-axis (back gauge movement). This configuration is suitable for straightforward bending tasks where high precision and repeatability are essential.

Advantages of 4+1-Axis Press Brake:

  • Cost-Effective: Generally more affordable than 6+1-axis models.
  • Ease of Use: Simpler to set up and operate, making it ideal for smaller shops or beginners.
  • Reliable for Simple Bends: Perfect for jobs that require consistent, straightforward bends.

6+1-Axis Press Brake

 

A 6+1-axis press brake includes the Y-axis, X-axis, and adds control over the Z-axis (lateral movement of the back gauge) and two R-axes (up and down movement of the back gauge fingers). This advanced configuration offers enhanced flexibility and precision.

Advantages of 6+1-Axis Press Brakes:

  • Complex Bending: Capable of handling intricate bending tasks with high precision.
  • Increased Flexibility: Allows for more versatile bending operations, accommodating various part geometries.
  • Efficiency: Reduces the need for manual adjustments, increasing productivity.

Which One is Better?

 

The choice between a 4+1-axis and 6+1-axis press brake depends on several factors, including the types of parts being produced, production volume, budget, and available operator skill level, but most important is your specific needs and budget. 

Choose a 4+1-Axis Press Brake if:

  • Your bending tasks are simple and do not require intricate angles or complex shapes.
  • You are looking for a cost-effective solution that is easy to operate.
  • Your production volume is moderate, and you prioritize ease of use.

Choose a 6+1-Axis Press Brake if:

  • Your projects involve complex and precise bends.
  • You need high flexibility to handle a variety of part geometries.
  • You aim to enhance productivity with advanced automation features.
Conclusion

Both 4+1-axis and 6+1-axis press brakes have their unique advantages and are suited for different applications. Assess your bending requirements, budget, and production goals to determine which type of press brake aligns best with your needs. Investing in the right press brake can significantly improve your metal fabrication efficiency and output quality.
