All operation of press brake must be carried out by qualified and experienced operators with signs posted. Do not put hands or other parts of the body between the press brake. Use the right press brake for working at heights without risk.
What should be prepared before using press brake?
How to operate press brake?
What are the warnings when using press brake?
When operating the press brake, in order to prevent the occurrence of problems, the preparations must be carried out.
Clean the oil stains on the appearance of press brake. The engraved line on the stop valve should be in the open position.
Turn on the press brake for a few cycles, ensuring that there are no abnormal conditions. Try cutting different thickness sheets. During trial cutting, the gap between the different blades must be adjusted because the thickness of the plate is different. Otherwise, the durability of the blade will be affected.
During the cutting process, turn on the pressure gauge and check the oil pressure value. If any abnormality, the relief valve can be dispatched to meet the specified requirements.
When operating the press brake, if abnormal noise or overheating of the oil tank is found, the press brake should be stopped and checked. The high temperature of the fuel tank does not exceed 60 degrees.
Turn on the press brake power and the key switch on the control panel. Then, press the oil pump to start.
The press brake must pay attention to the adjustment stroke. Be sure to test before operating. When the upper die of the press brake descends to the bottom, there must be a gap of plate thickness. Otherwise, it will cause damage to the mold and the press brake. The stroke adjustment also has electric quick adjustment and manual fine adjustment.
For the selection of bending notches, 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.
Step on the foot switch to start bending. You can release it at any time.
Before operating the press brake, check whether the motor, switch, circuit and grounding are normal and firm. Check that the control parts and buttons of the press brake are stuck in the correct position.
Check the firmness of the upper and lower molds that whether each positioning device meets the processing demands.
If the upper slide plate and each positioning axis are not at the origin, run the return-to-origin program.
After the press brake is started, run idling for 1 to 2 minutes, and move on the skateboard 2 to 3 times at full stroke. Troubleshoot the malfunction until press brake is normal.
The operator should be in uniform command, cooperating closely with the feeding and suppressing operator.

The hole of shearing machine is congested. Clean, grind, debug, inspect, repair or replace the overflow valve.
Shearing machine operator should master the operation of the shear hydraulic system. Whether the hydraulic system is working normally. Whether the hydraulic pump is abnormal. Check the cleanliness of the hydraulic oil used in shearing machine. Check the cleaning and replacement of the filter element. Whether the hydraulic components of shearing machine have been adjusted before failing. Whether the sealing component of shearing machine has been replaced. They also master the abnormal phenomena occurred in the hydraulic system of the shearing machine before and after the failure. They should be equipped with some knowledge about how to eliminate the failures causing shearing machine fail.
Check the actual working conditions of the shearing machine, together with system pressure, speed, oil, leakage, vibration and other parts.
Pay attention to the sound of shearing machine, such as attack noise, pump noise, and other abnormal noises. Judge whether the shearing machine is working normally.
Check the temperature of shearing machine to determine whether the working condition of the moving parts is normal.
Operate shearing machine strictly in accordance with the operating procedures. It is strictly forbidden to operate the shearing machine by non-designated personnel.
Add lubricating oil according to the requirements of the lubrication chart every time before starting the shearing machine. The oil should be clean and free of precipitation.
The shearing machine must be kept clean frequently. The unpainted part should be painted by anti-rust grease.
The lubricating oil in the motor bearing should be replaced and refilled regularly. The electrical part should be regularly checked for normal, safe and reliable operation.
Regularly check V-belts, handles, knobs, and buttons to avoid severely wearing. The spare parts should be reported for replenishment.
Regularly check and repair switches, insurances, and handles to ensure reliability.
Lubricate and scrub the shearing machine 10 minutes before leaving get off work every day.

The CO₂ laser cutting machine is one of the earliest gas lasers, developed by Kumar Patel in 1964. With high power and levels of control, CO₂ laser cutting machine can be available for places, where requires precision, mass processing, and personalization. It is achieved using a gas laser.
How does CO₂ laser cutting machine work?
What are the advantages of CO₂ laser cutting machine?
What are the applications of CO₂ laser cutting machine?
In aCO₂ laser cutting machine, light is produced when electricity runs through a gas-filled tube with mirrors at both ends. The discharge tube of the CO₂ laser cutting machine is filled with mixed gases such as CO₂, N₂, and He.
There are three different forms of motion for any molecule. One is the movement of electrons in the molecule, which determines the electronic energy state. The second is the atoms vibrate periodically around their equilibrium position, which determines the vibrational energy of the molecule. The third is the rotation of the molecule, which determines the rotational energy state of the molecule.
The CO₂ laser cutting machine uses the transition between the vibration and the rotation energy level of the CO₂ molecule to generate laser light.
l The CO₂ laser cutting machine doesn’t physically touch the material it is working with. Instead, it causes the material to melt through intense heat, causing minimal damage to the material and the machine.
l CO₂ laser cutting machines have low maintenance costs, which only need inexpensive replacement parts.
l CO₂ laser cutting machine is much safer than others since it does not use a blade. The beam is sealed in a tight lightbox.
