FAQs

What parts of the CB II press brake are monitored for positioning and control input?

Linear transducers (potentiometers) constantly monitor the bed-to-ram position and interface with the CB II control for programmable operation.

How do the standard LED control and optional multi-axis LCD control differ?

The standard LED control programs vertical ram motion only, while the optional multi-axis LCD control can sequence multiple depths and also coordinate optional backgage vertical and horizontal movement.

Which factors most affect part quality when operating the CB II?

Part quality depends on press brake condition and repeatability, operator ability, tooling type and condition, and the quality of material.
