Most Crowning Systems are available with CNC drive motors. With CNC the press brake operator needs only to enter the pertinent programming data into the machine's control, and the combination of the independent control axis and the CNC motor will automatically set the crown to the proper position prior to each bend. We also provides crowning systems with manual hand cranks that have digital readouts. These units are less expensive than the CNC controlled units and are therefore very popular with new press brake buyers and as retrofits to existing machines.
