WC67K- Hydraulic Bending Machine (Press Brake)

Standard Facilities: 

Sinomec makes an extensive range of high quality, precision mechanical or hydraulic, NC or CNC Press Brakes – ISO 9001 and CE Certified, The whole structure of the hydraulic press brake:

1. Welded structure: The press brake adopts whole steel welded structure. And it has enough intensity and rigidity. 
2. Frame: Ram synchronization during the stroke is controlled by a mechanical torque synchro system, which is steady and reliable. And the stroke of the ram is adjusted in the inter cylinders. The ram stroke (Y-axis) and the back gauge (X-axis) adopt ball-bearing screw and rolling guideway, quick speed, and high report positioning precision. The upper clamp is fitted with a compensation device.  
3. Hydraulic valves are from Germany Rexroth 
4. The hydraulic pump is from the SUNNY brand (USA venture in China)
5. Ball screw & Line guide rail Taiwan HIWIN
6. The main electric components are from Siemens or Schneider.
7. Hydraulic seals are from NOK, Japan

Control System

1. ESTUN E21 NC control + Frequency inverter
2. Optional Control system: China ESTUN E200, Delem DA-41S, DA41T
3. Worktable mechanical compensation or hydraulic compensation device is optional.

After-Sale Services

1. Free installation, trial start, and adjustment, training. Our technician is available at your factory and offers training on how to use our machines. As well, you may send your technician to our company to learn how to operate machines. 
2. The warranty period is 2 years. During the warranty period, we shall reply to the call or Fax from the user for the machine faults (except for faults caused by not abiding by the relevant operation regulations, or by force injury) within 24 hours.
3. We arrange final test before shipment. We run the machine for a few days, and then use the customer’s materials for testing. After making sure the machine is the best performance, then make shipments. 

STABLE MECHANISM:

• The torsion bar synchronization system will make left-right-side cylinders.
• An eccentric bearing sleeve makes ram pluralism adjust easy.
• Ram moves in low friction pertinax slideways.

LOWER NOISE:

• Double side Ball Screw drive (Taiwan HIWIN)
• High rigidity g guide bar or liner guide
• High efficient worm reducer
• Belt synchro two side
• The back gauge structure mounted on two sidewalls will make backstop movement more stable.

EASY OPERATE:

E21 NC control system control Y, X 2 axis

• 40 programs stored, 25 steps per program.
• Back gauge Concession function.
• Holding pressure unloading time setting mm/inch , Chinese/English.
• Workpiece counting.
• One-key backup/restore.

POWERFUL HYDRAULIC SYSTEM:

• Bosch Rexroth hydraulic system.
• Compact, low-maintenance hydraulic block.
• Bite-type pipe fittings will reduce oil leaking.
• Hydraulic overload protection.
• Oil tank level/temperature indicator.

EFFICIENT POWER:

Sunny Gear Pump

• Highly efficient low noise Internal gear pump
• With an Oil tank filter.
• G/B highly efficient AC Inverter motor
• Germany Siemens motor improves the life of the machine and makes the machine work with low noise.

EASY CONTROL:

• Schneider Limit Switch with high accuracy
• Pre-set, two-speed bending cycle giving fast approach, bending, and fast return
• Ram stroke control by precision mechanical stops built into each cylinder.
