A variety of press brake are now available in the market. However, they are mainly categorized as mechanical or hydraulic press brake, depending on the means of applying force. With the advancement in technology, the CNC press brakes come into being. CNC press brake has the capability to deliver force in a limited vertical space in order to punch or bend the metal sheet.
Why we use CNC press brake?
How does CNC press brake work?
How to calibrate CNC press brake?
CNC press brake is the most accurate and precise type of press brake. CNC press brake is a modernized and more accurate version of the hydraulic press brake that is controlled by computers.
The processing speed of CNC press brake is fast. The corner processing surface is beautiful with high strength.
CNC press brake transforms manual welding into fully automatic machine operation, improving quality and efficiency, CNC press brake reduces labor costs and shortens the production cycle of products.
CNC press brake is a new large-scale machine. The high precision is favored by many people. It can adopt flexible operation mode, which can be linked with two machines to solve the problem of processing long plates.
CNC press brake be operated and processed by a single machine to effectively improve the use. It reduces energy consumption. The compensation is automatically adjusted by the numerical control system, which is convenient and accurate.
A CNC press brake works quite similarly to a hydraulic press brake. However, the difference is that CNC press brake is controlled by slider stroke and backgauge. All you have to do is input the number of pieces that require bending along with the bending angle, getting the job done with accuracy.
CNC press brake has a ram fitted with a punch that forces the material being worked into a die. The material is formed into an angle corresponding to the angle of the die or the depth the punch forces it into the die.
CNC press brakes can be pre-programmed to bend the sheet metal through many various bends completing one part at a time. It uses a V blade to push on the sheet metal with pressure against a die.
The CNC press brake adopts electromagnetic force clamping so that the pressing plate can be made into a variety of workpiece with side walls. The operation is simple.
Metrology personnel required to calibrate CNC press brake need to open the cover of the saw that the optical components can be adjusted on the worktable, the spindle and the independent tripod. The time that spatial calibration process needs depends on the size of the CNC press brake. If the part is within the tolerance range by the three-coordinate surveying and mapping machine, the spatial calibration is not so necessary.
The trajectory of the calibrated CNC press brake is not a straight line but lateral movement. Traditional correlators cannot do this, except for the single-aperture laser correlation instrument.
When testing a CNC press brake, use a moderate probe to measure the proportion of the drawing part. The specified spatial error can be listed as an error table or offset table. The software can correct the coordinates of the probe.

The backgauge adopts imported ball screw and linear guide to ensure the positioning accuracy.
The CNC press brake uses a servo motor as an actuator. When the bending operation is not performed, the motor does not move and consume power. Therefore, CNC press brake is a product that meets the energy saving requirements. The servo motor has a higher degree of controllability so that it can be well adapted to the production needs of the modern industry.
The efficiency and the profitability of a CNC press brake are measured by the number of completed and correct parts produced in a given period of time.
Operators need to know CNC press brake completely. They also should know material type, thickness, flange dimensions and tolerances, angles and angle tolerances, and inside radius of angles.
The choice of tool is based on the drawing. Air bending, bottom bending, and coining are available. Select the tool that is at least as accurate as the specified type.
Tonnage charts are available for air bending. For bottom bending, a good tonnage may be four times than that of the air bending. Coining requires eight times the air bend tonnage.
If you have two or more CNC press brakes, make sure to choose the best-suited one. Remember that air bending cannot overload a CNC press brake.
Determine tooling position on the bench. If the tonnage requirement exceeds the concentrated load limit in the center of the CNC press brake, it can be off-center.
Install the tooling and align the upper and lower.
CNC press brake should be programmed properly, which is very quick.
Bend materials only after completing a good test bend. If something wrong, correct the program until a good part has been formed.

How to check press brake?
How to lubricate press brake?
How to maintain press brake?
Check whether the liquid valve of the press brake mold is fully opened. If it is oil contaminated, the filling valve spool is not flexible, resulting in insufficient filling. The filling valve of the press brake needs to be cleaned and reinstalled.
Check whether the solenoid coil of the overflow valve of the press brake is energized. Whether the voltage of the solenoid coil meets the standard.
Check whether the cartridge valve or the main valve core of press brake is stuck. Whether the orifice is blocked. Disassemble the overflow valve of the press brake mold. Clean and reinstall it.
Check the oil level of the mold oil tank of the press brake to see if the oil level is too low. If the filling port is not filled with water, the upper cavity of the cylinder is filled with liquid during fast forwarding, causing insufficient filling. Add the oil in the fuel tank to more than 5mm above the filler port to make sure to submerge the filler port completely.
All the rollers and corresponding parts in the press brake must be refueled, which is three times a week.
Put butter on the upper and lower blades of press brake. Add oil three times a week. Lubricate the clutch area of the knife.
The seal coil in the cylinder of the press brake must be cleaned and lubricated at the place where the sheet metal is bent.
The oiling work of the sliding bearing and the feeding frame of the press brake needs to be carried out every three days.
When refueling the place of the feeding shaft presser plate of press brake, we need to use a grease gun to inject the oil. Clean the place where the oil is added before refueling.
If it is to refuel the connection of the brake of press brake, move it back and forth after refueling. Lubricate it three times a week and pay attention to cleaning.
An inspection of press brake will allow to notice and address small issues before they become significant problems.
Verify that the press brake is in clean condition. The table and die area should be free of mill scale.
If the press brake is tooled up or a different toolset needs to be set up, verify the punch and die alignment and inspect the condition. The punches and dies should be free of dents. Indentations and cracks show that the tool has been overstressed needed to be reconditioned or replaced.
The proper operation of press brake, including up button, e-stops, foot pedal control, and indication lights should be in good condition within few seconds.
If additional guarding is present, make sure it is set up according to specifications.
Hydraulic oil is the lifeblood of press brake. It is vital to keep the oil clean and filling the oil reservoir. Check the oil level in the tank periodically. An insufficient oil level will cause erratic operation of the ram and damage the hydraulic pump.

The rapidly growing science of laser cutting machines is dominated by two main methods: CO₂ laser cutting and fiber laser cutting. Elias Snitzer invented the fiber laser cutting machine in 1961 and demonstrated its use in 1963. Serious commercial applications only emerged in the 1990s.
What are the features of fiber laser cutting machine?
How does fiber laser cutting machine work?
What is the future trend of fiber laser cutting machine?
The fiber laser cutting machine is much quicker when cutting thin metals. However, CO₂ laser cutting machine has better edge quality when cutting thicker materials.
The most valuable feature of fiber laser cutting machine is the price. The cost represents massive savings, both in initial purchase and during the lifetime. It doesn't require expensive optical mirrors.
The maintenance costs are a big selling point. There are fewer moving parts and fewer adjustments to make, resulting in lower downtimes due to maintenance. Parts lead to more maintenance and increasing costs. As light pulses are sent by the fiber cabling, fiber laser cutting machine does not require moving mirrors to generate the laser.
Using fiber laser cutting machine can increase cutting speed. When cutting a straight line of 1mm, the cutting speed of it is three times faster than that of others.
There is the chance a laser may bounce off the reflective material to damage the equipment. Traditional laser cutting machines are not often used when cutting brass, aluminum and copper. With fiber laser cutting machine, the reflective material problem is no longer an issue, which in turn allows for the cutting of these materials.
The first fiber laser cutting machine was introduced in 2008 at EuroBlech. The conveying methods of different laser beams allow to cut highly reflective metals, like aluminum, brass, copper and galvanized steel.
Fiber laser cutting machine is simpler and more durable. The fiber laser light is created by banks of diodes. Then, it goes through optic cables to get amplified. Because the cables are mixed with rare elements, such as erbium and thulium, which are adopted to amplify the light. The lens focuses the light to form a laser beam ready for cutting. It does not need any gases, no mirror realignments, and no warming up.
Fiber laser cutting machine uses an optical fiber cable made of silica glass to guide light. The laser beam is more precise than other types due to its straighter line and smaller space.
Fiber laser cutting machine has a bright future. Fiber has set eyes on replacing CO₂ to be the leader in the industry. Although the majority of the market is still in the grasp of CO₂ laser cutting machine, fiber laser cutting machine is catching up.
The demand for laser cutting machine is often accompanied by the development of China's sheet metal processing industry. China has become the largest consumer of sheet metal processing.
At present, most are plasma cutting machines, which have problems in processing speed. Therefore, efficiency and accuracy have become the main obstacles. The introduction of fiber laser cutting machine can greatly improve the efficiency of sheet metal processing and the cutting accuracy, together with reducing the waste of processing raw materials. The operating system and interface are in line with ergonomic requirements to effectively reduce the error rate and accidents
It is now the third generation, which will still occupy a leading position in sheet metal processing in the next 20 years.
