Brief Introduction of sheet folding machine
CN BEST press brakes have the advantages of high quality, durability and highprecision.
The main frames of machine are constructed from rolled, stress
relieved solid steel to prevent distortion during the bending
process and under extreme continuous loads.
Adjustable synchronized torsion bar with positive stop system which
is controlled by
the Digital Control unit, the bending beam parallelism tolerance
will be consistent and
accurate to 0.01mm.
Function of sheet folding machine
A press brake, also known as a brake press, is a machine tool for bending sheet and plate material, most
commonly sheet metal. It forms predetermined bends by clamping the
workpiece between a matching punch and die.
Typically, two C-frames form the sides of the press brake,
connected to a table at the bottom and on a moveable beam
at the top. The bottom tool is mounted on the table with the top
tool mounted on the upper beam.
Main Features of sheet folding machine
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
• 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
• Oil seals by Japanese, NOK.
• Overload & overflow protection to ensure there is no leakage
and protect hydraulic system, and the oil level can be
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
• 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.

brake press Installation Services are available with all our brake
press. We dispatch technician tocustomer's factory for installation and preoperation of machines. ( Customers only need to pay the airfare and hotel )
Our technician is available to your factory and offer training of
how to use our steel bending machine.
As well, you may send your technician to our company to learn how
to operate bending machines.
We guarantee the quality of our brake press (e.g. processing speed and working performance is the same as the data of samples making). We sign the agreement
with detailed technical data.
We arrange final test before shipment. We run the machine for a few
days, and then use customer's materials for test. After making sure
machine is the best performance,then make shipments.
CN BEST is good,I have cooperated with them for almost 8 years,My
clients trust their quality,I like their good service.
