Diamond BH Series

The Diamond BH “Dual Drive” system controls high-speed up and down movement with a ball screw and bending movement by the servo-hydraulic piston. The Dual Drive System allows high-speed down-movement at 200 mm per second with high repeat-stop accuracy. In addition, the Dual Drive System offers energy savings thanks to an assist device that stores the energy of down movement and returns it during ram up movement. The ram floats on a gas cushion, thereby greatly diminishing the weight to return the ram to the top of the stroke.

Accuracy is key to the BH Series. Ram cylinders powered by AC servo motor piston pumps deliver positioning accuracy unparalleled in the industry. Combined with the accuracy (4 micron) of the back gauge driven by MITSUBISHI motors everytime part after part! With Automatic Thickness Detection, angular irregularities are minimized due to material thickness and off-center bending, the BH Series proves to be an amazing machine tool.

The BH Series appeals to operations requiring lightning-fast speed and high precision parts or customers looking to improve their efficiencies while reducing operating costs. For the quickest and most accurate brakes available, you can count on the BH Series hybrids.
