Which press brake is best?

Question: We recently acquired a new press brake, and to be honest, I’m not thrilled with the outcome. My employees are less than pleased with the transition. They appear to be struggling to adapt to the new technology and methods associated with the press brake. It seems they are spending significantly more time on machine setup than they ever did with our previous system.

I invested heavily in new tooling, which unfortunately does not align with our existing stock tooling. To maintain production levels, it will be necessary for us to purchase additional adapters to accommodate all of our legacy tooling.

What should I have known prior to this expenditure on a press brake and tooling? While it's too late for me now, I hope to help other shop owners avoid making similar mistakes.

Answer: This is a frequent question, and despite my experience, I find that it is inherently subjective. There isn’t an ‘absolute best’ press brake. However, there is a best press brake for your specific needs, which is the essence of your inquiry.

Evaluate Your Operations Instead of Just Numbers

You may feel that you need a new press brake and have budgeted for the purchase, but what's the anticipated return on investment?

There is a plethora of drive systems and types you can choose from. Which one suits you best? What level of technology do you actually require? To make an informed decision, you should have a clear understanding of the distinct types of machines and their specific roles within the industry.

Mechanical Press Brakes

The design of mechanical press brakes harks back to earlier times, relying on a flywheel that can deliver up to 150% of its rated tonnage. Due to their construction, mechanical presses are not typically suitable for air bending in a production context; they are mostly utilized for operations like coining that require precise control of internal radius.

These machines can handle occasional tasks such as manufacturing truck bumpers or fence posts. However, accurate work will demand considerable skill and significant production time, with each bend requiring unique tooling, resulting in multiple handling of parts.

Hydraulic Press Brakes

The hydraulic press brake operates using hydraulic oil pressure, which drives a motor that moves the ram. This design allows full power throughout the ram stroke and is significantly quicker to reset than mechanical brakes. However, they are optimized for American-style tooling.

CNC Hydraulic and Hybrid

These machines leverage hydraulic systems that can provide high precision and rapid setups, ideal for air forming applications. They integrate multi-axis CNC controls that can be tailored for American, European, and new standard tooling, ensuring high repeatability.

Electric Press Brakes

Characterized by speed and efficiency, electric press brakes use electric motors to propel the ram, enhancing precision and accuracy with the right tooling. However, the technology requires further refinement to meet the needs of larger machines.

Choosing the Right Controller

Your choice of controller greatly depends on your specific production requirements. If high precision and complexity are needed, opting for a more advanced controller is critical. Nonetheless, consider your team's ability to adapt to new technologies and workflows.

Next Steps: Tooling Considerations

Before choosing a new press brake, it's important to understand the tooling involved. The type, style, and application of the tooling play a crucial role in your decision-making process. I’d argue that tooling is the most vital factor in your selection, a topic which will be explored further next month.
