Hydraulic CNC Press Brake WC67Y-40T×1250
The Whole Structure of Press Brake:

Totally European design, streamlined looking,Monoblock,Welded steel frame rigid to deflection moment and high tensile
with ST44 A1 material.

ACCURL Press Brake,designed according to the most modern design techniques, are the best product from the
price/performances point of view.

From the structural point of view,the traditional high level standards of ACCURL are not changed and they are now
improved thanks to the numerical analysis techniques (FEM) and statistical research methods (DOE).
1. Hydraulic System:

Adopt integrated hydraulic control system, more reliable and easy for maintenance.Hydraulic system is from Bosch Rexroth,Germany.

All pipes, flange and joint with vibrations proof and leakage proof design and setting .

All seals in cylinder is PARKER from USA,the most famous brand,good quality and high performance

Overload overflow protection is outfitted to hydraulic system,which can assure no leakage,and the oil level can be read or
seen directly.

The hydraulic system is made in compliance with current regulations (Directive 98/37 EC).
2. Electrical System:

Electrical Cabinet under the standard of IP65, Electrical under international CE Standard, safe and reliable, strong anti
interference capability.

Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to
operate.

Front Side Covers with safety switches, Back light safety guards (Category-4),Foot pedal conforming to CE regulation.
3. Synchro control system:

Patented hydro-mechanical system for exact parallelism and a high repeat accuracy

The worktable adopts the particular design,reducing the crowning distortion amount of lower tool effectively.

Adopt steel torsion bar synchro system,simple in structure and high in accuracy,ensures the parallelism between beams is
used for the synchronism.
4. Ram and Dies:




Up punching dies will be cut into section as the requirement as below
Fractional set:25mm 30mm 40mm 45mm 50mm 125mm 100mm right 100mm left.
The equipped standard Dies, special non-standard mold is available under client's requirement according to real workpiece
situation.
The Machine By E21 NC Control With the point of programming, can automatically adjustable the backgauge size and
bending depth;
5. Backgauge

Standard X-axis travel is 500mm with third gauge step capable of gauging parts up to 600mm with standard back gauge
(most machines)

Back gauge fingers with two gauging steps used one for short and the other for long bending depths.

Back Gauge positioning fingers move along linear bearings with ±0.01 mm. positioning tolerance.

Optional:Estun E210 or Delem DA41 cnc controller auto controls the Backgauge,Bending Angle,together the numbers of
workpieces accurately.
6. ESTUN E21 NC Control System
 The ESTUN E21 control provides a complete solution for conventional press brake applications for 2 axes.
 In view of characteristics of press brakes, photoelectric encoder is equipped to display position of backgauge and dead
block.
 Special functions like one side positioning display and spindle allowance offset
are available to ensure unity for displayed position and actual position of
backgauge.
 Integrated with time replay, soft limit switch and power down position
memorization function, E21 provides a high cost performance.
