NC (TORSHION BAR) Press brake E21 Series
NC Press Brakes are synchronous with torshion bar which connected 2 sides of the cylinder, it is conventional standard due to its high cost performance. However as industry products, the nature of all press brake is to create value for its consumers, it is another and more important side to maintain quality simoutaneously with cost reducing.

Torsion bar adjustament parts, optional
As a physical synchronization to be connected by torshion bar, small deform will happans in years of hard work,tollerance emerge and increased.
The unsynchronization performed in the angle difference of 2 sides, which is a headache problem for all users and vendors.
To solve this problem, our team invent this adjustment design on torshion bar, to adjust and eliminate the tollerance, and get back your machine to full precise angle on 2 sides.
DSP LASER SAFETY SYSTEM WITH OPTIONAL:
ETERNITY Press Brake Standard with DSP visible laser protection compliant to EN12622 regulation. The beam protects the press brake operator from the danger of being crushed between upper & lower tool.
Advantage:

- Box-shaped part bending feature
- Innovative tooling grid guarding pattern
- Completely foot peddle controlled operation
- Auto-blanking for automatic box and side wall detection
- UL approved
- Type 4 patented process control
- Safe Release” supports are unhooked without damages in case of collision
Optional:
- Lazersafe-Defender Plus
- Lazersafe-Defender Plus
ETERNITY machines Optional for comply with the strictest EU regulations with reference to safety. The devices installed guarantee thorough safety of the operator without reducing the pace of work.
BACK GAUGE SYSTEM IN CNC STANDARD
ETERNITY E NC press bake are equipped with CNC standard back gauge for a advancement in speed and precision, to assure best repetitiveness and higher precision in angle positioning.
Feature:
- Stroke X= 600-800mm
- Max. speed X= 350mm/s
- Stroke R= 200mm (manually adjust)
Advantage:
- X axis with Hiwin linear guide and ball screw.
- Manual Z1,Z2axis with linear guide
- Less noise, greater durability and great precision
- Unprecedented positioning repeat-ability within 0.05mm.
- High-speed movement on all axis to ensure that the gauge fingers are positioned as quickly as the operator positions the part.
Tooling
Our offer includes standard V punch die, with various channel at lower die, for bending of different depth, and equipped with quick clamp system.
Material: 42CrMo, with heat treatment( Quenching), HRC48-52
Arc, sinking, angle dies available, and customer design acceptable.
Free section, for the convenience of combine or small piece.
Crowning systems, V axis （Optional）
Precision: 0.01mm, scope: 0-3mm
Eternity offeres both machanical and hydaulic crowning system both of which ensures a constant bend angle across the full length of the machine. This is achieved by pre loading the machine, to offset any possible deflection under load or compensate for any tool wear, so that under load contacting surfaces are parallel to each other.
With CNC crowning systems the press brake control is preprogrammed with machine characteristics and deflection data.
