Diamond BH Series

This dual-drive hybrid makes short work of any project with long-term, high-speed, energy-efficient operation.

When you need lightning-fast, highly precise processing, hybrid press brakes are up to the task. But what sets our BH series hybrid press brakes apart from the pack?

When it comes to repeat/stop accuracy, easy operation, or keeping your shop operating more cost-efficiently than you might have previously thought possible—without sacrificing quality, capability, or speed—the BH series bends the rules just as easily as it bends thick material with the ease of thin gauged material all while maintaining the tightest of tolerances.

World-class productivity achieved through our proprietary technology results in greater reliability, machine uptime, and reduced operational costs and ease of operation – part after part, year after year – experience the difference with the BH series.

Diamond BH Series Right

  • The electric AC servo motor hybrid and ball screw drive mechanism isn’t just fun to say. It achieves performance that outclasses other electric and hybrid press brakes, all while ensuring long-term accuracy and minimum internal wear. The result? A machine you can trust to keep doing everything you need it to, day after day.


  • Form complex parts easily and cost-efficiently. The BH series is built from the ground up to deliver the best results with the fewest required resources. It’s soft on electricity consumption but still tough on any project your shop can throw at it.


  • An easy, intuitive 22” color multi-touchscreen running Windows makes everything from day-to-day operation and programming to 3D simulation simple and quick. That means that this machine has the potential to achieve peak performance in nearly any scenario under any operator. Finally—simple, stress-free functionality.

  • The Diamond BH dual-drive system controls high-speed up/down movement with a ball screw and bending movement by the servo-hybrid piston system for unbeatable functionality.
  • The dual drive system allows high-speed down movement at 200 mm per second with high repeat-stop accuracy while still offering energy savings thanks to an assist device that stores the energy of down movement for the industry’s fastest cycle time 2.3s.
  • The ram floats on a gas cushion, thereby greatly diminishing the weight to return the ram to the top of the stroke, resulting in lower operational costs for greater cost-efficiency.
  • Ram cylinders powered by AC servo motors with 1 micron repeat accuracy and combined with a back gauge, accurate down to 4 microns, the BH Series delivers positioning accuracy unparalleled in the industry, part after part.
  • With automatic thickness detection & compensation, angular irregularities are minimized due to material thickness with no added options or external measurement device needed; the BH series holds tolerances some machines can only hope to do with angle measurement systems.

  • "The accuracy and repeatability are outstanding. I had one job running for five days straight—there was no difference from the first part bent on day one to the last part bent on day five. All of this plus the reduced setup time translates into higher profitability."

    Milan Popik Jr, Owner at Metal Tronics view case study
  • "“Press brake operators of all skill levels can easily set up complex jobs. This saves tremendous time and resources. Press brakes have not changed that much mechanically over the years, but technology like automation and diagnostics can really set you apart from the competition."
