Special Bending tools

Offset Bending, Edge Bending, Twist Bending

The EHRT bending machines of the Professional Line are made for high loads in industrial operations. Long wear and unrivalled accuracy characterize these machines. The Professional Line machines are exceedingly powerful CNC bending machines with spring back compensation. They are able to bend single pieces as well as small batches with the same precision and efficiency as series-produced parts. A bending accuracy of +/- 0.2° starting from the first work piece is achieved due to calculated spring back compensation and the use of electronic tools. The latest SV version supports an operation speed of up to 50 mm/s. Tools are changed quickly by using the simple plug-in system.

 

WORK PIECES

With a bending force of 300 kN, the Professional Line is able to bend materials of up to 160x20 mm (copper). The hydraulic cylinders are located under the working face to allow for a maximum amount of work space. Special bending tools render even complex bends possible.

CNC STOP

The Professional Line features a CNC stop with a traverse path of approximately 1500 mm, or 2000 mm available. Additional extensions are available on request. The bending software PowerBend accurately calculates the flat length as well as the stop position and transfers the results directly to the CNC control unit. High production accuracy is assured.
 

ANGULAR MEASUREMENT

Our measuring accuracy is 0.1°. This is attained by using bending prisms with electronic angular measurement technology. The computer then calculates the required final stroke. The spring back of every bend is compensated regardless of material type. Our high angle accuracy of +/- 0.2° is achieved instantly with the first work piece. No adjustments are required. Material waste amounts will drop considerably. Even inconsistencies within a single piece of material are automatically adjusted.

STROKE MEASUREMENT

If the bending prisms with integrated angular measurement cannot be used due to their size, bending prisms without angular measurements can be used. Perhaps the distance between two bends is too short. In such cases the control unit can be switched from angular to stroke measurement. This method allows the selection of the bending ram distance. Setting accuracy is +/- 0.1 mm. A final stroke is usually not required.
 

ON-GOING DEVELOPMENT

We incorporated many customer requests into the development of this line, as well as our own more than 50 years of experience in the bending machine industry. This machine is our most ergonomic machine to date.

BENDING SOFTWARE POWERBEND

EASY HANDLING

The Microsoft Windows® based software, PowerBend, is easy to learn since there are no CNC programming skills required. raining is accomplished smoothly. All necessary inputs are prompted and displayed on the screen. Inputs can be corrected at any time and minimum distances are checked instantly to guard against improper inputs. The operator is allowed to use outside, inside, center line, and radius dimensions. Software can be switched between mm and inches.

CALCULATED VALUES

The BasicBend software automatically calculates the flat length of each part being bent and determines the exact position of the side stop. Up to three bends can be calculated for one work piece.

PROGRAM STORAGE

The program for each work piece can be stored as alphanumeric names up to 24 digits. The database allows storage of up to 200,000 different parts which can be located easily using the search and sort options. Networking with other EHRT machines and external workstation is easy. Parts can be programmed externally and quickly transferred which increases the overall productivity of the machine.
