TECHNA-FAB PE Tandem Synchronised Press Brake

TECHNA-FAB PE Synchronised Press Brake uses the modern synchronized hydraulic system, which continuously monitors and adjusts the [Y1+Y2] cylinder axis positions using optical linear scales, ensuring precise and parallel bending along the full length of the machine.

This synchronized technology is far more accurate than the older torsion bar “dead stop” design, and allows consistent bending across a wide range of material thicknesses and V-die openings.

The PE Press Brake offers a strong price-to-performance proposition in the synchronized press brake category.

Controller options include:

• Cybtouch (8 PS or 12 PS)

• Delem DA-Series (DA52S, DA56, DA66T, DA69T)

These provide powerful CNC features, including 2D graphical touchscreen programming and 3D visualization for both simulation and production. The controllers offer multitasking, Windows-based application support, Delem Modusys compatibility, USB and peripheral interfacing, and sensor bending/correction functions.

A well-dimensioned welded frame and stable hydraulic system provide reliable performance for metal bending operations.

Operator safety can be configured with infrared light curtains, dual safety circuits, and relay protection.

Electrical and hydraulic components are globally sourced, and can be supported here in the UK with our JPS Machinery Ltd in-house service and technical team.

Accuracy Considerations
The synchronized hydraulic system offers a [Y1+Y2] axis positioning accuracy of (+/– 0.01 mm).

This is 10× more precise than a torsion bar “dead stop” press brake, which is typically only accurate to (+/– 0.10 mm).

For sheet metal bending, this higher accuracy translates directly to more consistent bend angles. For example, when bending 2 mm material in a 16 mm V-opening, the angle variation is reduced to within a fraction of a degree, compared to the 2° variation common with dead stop systems.

Angle accuracy also improves when using wider V-openings, making the PE series suitable for both thin sheet and heavier plate bending.

Options and Expandability

• CNC controller options up to 8 automatic axes, with ancillary equipment and offline software.

• Backgauge configuration starts with 2 automatic axes [X+R], with optional [Z1+Z2] axes.

• Lower deflection table option available.

Note: Anti-deflection (crowning) systems should be considered a fine-tuning tool, not a primary method of compensating for machine or tooling limitations. Overuse can create unwanted curvature (“banana effect”) along the bend length.

System Explanation – Synchronized Hydraulic Press Brake

Unlike the torsion bar system, the PE synchronized press brake achieves accuracy through:

• Hydraulic cylinders on each side of the machine, independently controlled.

• Optical linear scales mounted on the side frames, which continuously measure Y1 and Y2 movement.

• CNC system control, which ensures both cylinders remain synchronized within a tolerance of (+/– 0.01 mm).

This ensures that the top beam remains parallel to the bottom beam throughout the bending cycle, eliminating angular deviation and improving repeatability.
