What should be considered when using CNC press brake?
Close the rear protective door of the CNC press brake. Turn on the power. Turn on the switch on the control panel of CNC press brake. Then, start the oil pump. The CNC press brake does not operate at this time. Release all emergency stop switches.
Adjust stroke. Pay attention to adjusting the stroke when using it. You must test it before bending. There must be a gap of plate thickness when its upper die descends to the bottom. Otherwise, it will cause damage to the CNC press brake. The adjustment of the stroke also has electric quick adjustment.
For the selection of bending notches for CNC press brake, a notch with a width of 8 times the thickness of the plate should generally be selected.
Backgauge adjustment generally has electric quick adjustment and manual fine adjustment, which is the same as the shearing machine.
Press down the blue "reset" button on the pedal and the "reset rearguard" button on the electric box, ensuring that the two blue reset indicator lights are off.
Turn the function forwarding switch to the "auto" position and press the motor start button after the controller self-test is over.
The CNC press brake finds the reference point and loads the corresponding bending program. Ensure that the mold installed in the CNC press brake is consistent with the programmed mold. Ensure that the sheet material is consistent with the programming page.
Remove the lower blade of CNC press brake and clean it piece by piece. Select one side to install tightly. Check the straightness of the blade in the horizontal and vertical directions.
Remove the upper blade of CNC press brake and clean it piece by piece. Then, the operation is same with that of the lower blade.
The upper blade is fixed. We adjust the blade gap by adjusting the lower blade.
The left and right screws of the lower blade increase the clearance. Loosen the four bolts on the table of the lower blade.
Manually turn the upper blade down to the proper position. The operator adjusts at the blanking area of the CNC press brake.
Use a feeler gauge to roughly adjust to 0.5mm from the unoccupied part of the upper and lower blades.
Manually turn the blade to the middle position and adjust it to 0.5mm.
Manually turn the blade up to the right position where the upper and lower blades are not disengaged. The middle position is roughly adjusted to 0.5mm.
Manually turn the upper blade to the proper position and start fine adjustment.
Before working, you must check the surrounding area of CNC press brake for any objects that may cause harm to it. Make sure the surroundings are clean, especially backgauge. Check the position of the oil mark in the oil tank. Check the hydraulic part for leaks.
The CNC press brake should be operated by professors. The operators must wear the corresponding labor protection supplies.
After turning on the power switch of the CNC press brake, do not start the oil pump immediately. Start the oil pump only after the computer screen displays normal.
After starting the CNC press brake, run it for 2 to 3 minutes without anything. Run the slide block at full stroke for 2 to 3 times. Check the motor and CNC press brake for noise. If the temperature is low, the oil tank and oil circuit must be preheated.

Laser cutting machine adopts computer-aided design to cut for precision. The process has evolved since it was used to cut diamonds. As the laser cutting machine continues to be used for many industrial purposes, it is also growing in popularity in schools and small businesses.
What are the types of laser cutting machines?
How to choose laser cutting machine?
How to use laser cutting machine?
In terms of cutting material types, there are two types of laser cutting machines: metal and non-metal laser cutting machine. A metal laser cutting machine is used when metal materials are needed, while a non-metal one is to cut non-metal materials.
Classified by laser types, the laser cutting machines can be divided into three types: fiber, CO₂ gas and YAG. Now, the mainstream type of laser cutting machine in the domestic market is fiber laser cutting machine.
According to the laser output power, laser cutting machines involve high-power, medium-power and low-power laser cutting machine. In the industrial field, high-power ones are needed, while the medium-power ones are main in the laser engraving field.
As far as the cutting board size, the laser cutting machines contain standard-format and large-format ones. The cutting length of the large-format laser cutting machine in the X-axis direction is more than 8000mm, and the cutting width in the Y-axis direction is more than 2500mm. For the standard-format one, it is generally about 3000mm multiply1500mm and 4000mm multiply 2000mm.
The cutting plates have flat plates and three-dimensional plates. Flat plates are cut by a flat laser cutting machine, while three-dimensional plates can be cut by a three-dimensional five-axis laser cutting machine.
Make clear processing demands, such as processing material type, size, and accuracy tolerance. It helps determine which type of CNC laser cutting machine you need. For metals, you may look for a metal or fiber laser cutting machine.
Choose the right laser cutting machine manufacturer. It matters a lot concerning the quality. Good manufacturers provide high-quality machine with a complete quality assurance system and after-sales service system.
Choose the configuration. You can negotiate the configurations and specifications with the manufacturer. All the configurations shall be based on specific processing requirements. It may include lasers, laser heads, servo motors, guide rails, and water coolers. If you are not sure about the specifications, you can introduce your requirements that the manufacturers will recommend the suitable one.
Decide what material to cut or engrave. Laser cutting machine can cut and engrave wood, plastic, cardboard, foam, fabric, and thin sheets of metal. Any material containing chlorine cannot be used due to the toxic fumes.
Choose an image, such as a photo, a computer drawing, and computer text. Make sure the image has plenty of contrast without many shadows. Upload the image into software that is compatible with the laser cutting machine. Set the dimensions of the image to match the size of the material. Optimize the image.
Place the material in the center of the laser cutting machine. Press any key to let the laser test the dimensions across the mat. If your material has a bend, place a weighty metal rod to hold it down.
Clean the lens with rubbing alcohol. Set the lens height. Most laser cutting machine will have an automatic lens height sensor or button. If not, you will need to adjust the height manually.
Turn on the fume extractor to suck all the fumes and dust from the material out of the laser cutting machine
In the material settings, select what kind of material you are using. This will affect the settings of the laser. Select what type of cuts you are making. Press print.

Press brake is a mechanical or hydraulic machine for bending sheet metal and plate material, which is common in engineering workshops. Press brake requires different methods of approach to achieve the desired results. From forming wind tower poles to intricate electrical cabinet components, press brakes are a vital tool.
What are the common faults of press brake?
How to avoid electric leakage when the press brake is working?
Why there are errors when using press brake?
Press brake makes poor surface roughness of the workpiece. The tool tip of the press brake is damaged that is not sharp. The press brake resonates leading to the unstable placement. The press brake has a crawling phenomenon, resulting in poor processing technology.
The workpiece produces taper-size head. The level of the press brake is not adjusted properly that one side is high and the other is low, resulting in uneven placement. When turning the long shaft, the material fed is too hard to be cut deeper. The tailstock thimble and the spindles are not concentric.
The size of each workpiece is inconsistent. The carriage of the press brake runs at high speed for a long time, resulting in the wear of the screw and bearing. The repeated positioning accuracy of the tool holder produces deviations during long-term use. The carriage can accurately return to the starting point of processing every time, but the size of the processed workpiece is still changed. It is generally caused by the main shaft, caused by the high-speed rotation to wear.
For the press brake, it is inevitable that there will be leakage in the working process. If the leakage is not handled in time, it will damage to safety.
In order to avoid the occurrence of electric leakage when the press brake is working, the press brake must be equipped with a leakage protector, it is a current-driven leakage maintenance device, which has a good effect on the protection of the press brake.
When operating the press brake, if the insulation of the electrical installation equipment is damaged, the cover will be charged. The correct grounding and zeroing work must be done. The electrical installation of the press brake should be maintained with high-voltage grounding to reduce the risk of electric shock.
The wiring operation of the press brake is also very simple. It is enough to connect the metal shell and the common maintenance neutral line firmly. Lead out from the neutral line on the power side of the leakage maintainer. Under the protection of its maintainer, the press brake can maintain a good and stable situation.
The outer circle of the bend is a cone. The connection between the front and rear centers is not coaxial with the spindle axis, which is caused by the wrong position of the tailstock center of the press brake.
The workpiece vibrates when bending. It may be that the tailstock sleeve of the press brake extends too long or the support of the workpiece is too loose. The mold is not sharp enough or the arc is too large. The bearing clearance of the rotary center is large. The clearance of the medium and small sliding plates is too large.
The mold does not meet the requirements. The mold and the main shaft axis of press brake are not on the same axis. The circular runout caused by the wear of the bearing. The center hole of the workpiece is not cleaned or is fuzzed. The center hole does not work because the lever in the center of the mold touches the end face of the chuck.
