Control Options

Bertsch offers a range of control units—from hand-held pendant to the pedestal-mounted CNC.

CNC Control

Manual machines, equipped with digital readouts, are the most popular type of bending roll. These machines are capable of rolling simple rounds and radii by adjusting roll position and monitoring the digital read-outs.

Bertsch’s Roll and Repeat™ Basic CNC Control provides more versatility by having the ability to store bending steps in memory, for retrieval at any time – simply add the step-by-step sequence into memory, and the machine repeats the sequence for each part. The Roll and Repeat™ system provides flexibility, not complexity, and minor adjustments can be made to adjust for material variations when necessary.

When rolling complex geometry, it is beneficial to visualize the bending process graphically. Bertsch’s high level CNC Control is a powerful, user-friendly control that improves the versatility and repeatability of your Bertsch Plate Roll. Using a SIEMENS Industrial PLC and dedicated software, it can be operated in either Computer Assisted or Manual modes.

Computer Assisted Mode allows the operator to work with icons on a graphic screen to choose the basic shape and then input simple data such as: Plate Thickness, Plate Width, Yield Strength and Desired Diameter.

The powerful software calculates the necessary theoretical positioning for all rolls and rotation requirements, including sequencing of steps.

For highly complex shapes, or experienced operators, the machine can be programmed quickly in Manual Mode. This single screen allows many steps to be programmed quickly and easily. Standard with 4 Axis (3 lower roll positioning and rotation control), it can be upgraded to as many as 13 axis for more complex or involved shapes and can include support systems, ejectors, feed tables, and much more.

As with any CNC program, the quality of your finished parts depend heavily on the consistency of raw material and availability of accurate test data. Minor adjustments will be necessary from one material lot to the next in order to achieve the most consistent results.
