WE67K-100T/2500 DA52 CNC Metal Sheet Press Brake Machine

Overall welded and processed structure.

Closed loop control mode composed of electric-hydraulic servo valve and measure ruler.

Ensure the highest control precision, bending accuracy and repositioning accuracy are also reach to the highest level.
Back gauge mechanism can be multi-axes controlled.

Integrated hydraulic system decreases the pipe connections, oil leakage, and increases the stability and overall beautifies.

Worktable equipped with hydraulic and mechanical compensation to avoid the deformed upper beam from affecting the quality of the work piece, it is automatically adjusted by the CNC controller with convenient and accuracy.

CNC controller normally uses Holland DELEM, Italy ESA, Swiss CYBELEC, all with multi-languages.

1.The whole structure: 

• Steel plate welded structure, hydraulic transmission, accumulator return, holistic processed, vibrating to eliminate stress, high strength and good rigidity. 

• Mechanical torque system makes sure the synchronization of cylinders.

• The stroke of slider and back gauge is adjusted automatically by double servo motors or transducer, and showed on CNC Mechanical torque or NC control panel.

 • Slanting wedges can be chosen to install on the top dies which can be adjusted by hands or automatically. Hydraulic compensation system is installed under the worktable.

2. Hydraulic system:

 • Hydraulic control system by BOSCH-REXROTH Germany or FIRST America.

 • Oil seals by Japanese, NOK.

 • Overload & overflow protection to ensure there is no leakage and protect hydraulic system, and the oil level can be read directly.

3. Servo motorized back gauge:

 • CNC Back gauge system with X axis by AC servo motor driven ball screw shafts and on linear bearings with an accuracy of 0.01mm.

 • Back gauge has well enough mechanical strength and rigidity with tank-type gauge structure. 

• High-precision ball screw and linear guide-way. Particular finger-stop design, enlarge the range of back gauge.

4.Electrical parts and protection device:

• Schneider or Siemens Low-voltage apparatus. In accordance with international standards, reliable safety, long life, good anti-interference ability, a radiation unit is fitted in electrical cabinet.

• Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch, easy to operate. 

• Light screen protection or Laser protection are optional.
