Are laser cutting machines dangerous?

Laser cutting machine allows for precise measurements and for users to get the exact dimensions. But the process can do harm to our health because of the harmful fumes emitted. It is more dangerous if workspaces do not have the air filtration systems.

Laser cutting machines are classified by the American National Standards Institute, as a Class 1 laser. They are not overly hazardous that they do not emit high levels of energy. Laser beams are hazardous during the cutting or engraving process because air contaminants are released. Harmful emissions are usually associated with Class 3B or 4 lasers. Chemical vapors, aerosols or smoke can be emitted when a laser beam is interacting with various materials.

During the cutting process, high temperature causes the surrounding air to expand. Once materials are cut by the laser cutting machine, they will emit gases that rapidly expand and release dangerous particles.

Is a laser cutting machine strong enough to cut a hand?

While laser cutting machine is relatively safer compared to conventional methods, the operators still practice with caution as the laser is powerful enough to burn skin and cut a hand.

However, the possibility that an accident would occur by a laser cutting machine is very low because it has a safety lid that can be closed or opened at any given time. The cutting process is done in a safe and controlled environment.

The disadvantage of laser cutting machine is that it cannot work on thicker metals. Its cutting capability depends on the material thickness and laser power. But even with this limitation, it doesn’t mean that the cutting power should be underestimated because it is still strong enough to cut a hand in a matter of seconds.

What are the factors affecting laser cutting machine price?

We all know that brand is an added value of laser cutting machine. The brand effect is reflected in the machine quality, kits, parts, performance, and after-sales service. The laser cutting machine of big brands will have higher prices than those of small factories.

The price of large-sized laser cutting machines is higher than that of small-sized ones. The price of the customized laser cutting machine is higher than that of the regular-sized ones.

The laser is the core optical component of the laser cutting machine. Different laser generators have different laser beam qualities. Imported lasers are superior to domestic lasers in terms of stability and beam quality. For the same brand laser generator, the greater the laser power, the higher the price.

Other key components mainly include guide rails, rack and pinion, motor, and water chiller. They also affect the price.

How to grasp the size of bending for press brake?

The main purpose of using a press brake is to grasp the size of the bending.

Avoid using a press brake to bend the edge or large-angle alignment.

Preliminary inspection is carried out before formal processing. Cyclic inspection is carried out during the use of press brake.

In order to avoid accumulative errors, the unfolded size must be measured every time when material is added.

Choose a good processing method and a good technical preparation method to simplify the processing of press brake.

The press brake selects the appropriate machine according to the accuracy requirements of the processed products.

Do not choose tools that have decentraction. Make sure that the tip of the upper die of press brake is on the same straight line before processing.

For products whose edges must be bent by a press brake, the front bending angle must be less than 90 degrees.

Determine the accuracy of the measuring instrument before processing.

How should you use press brake?

Strictly abide by the safe operation regulations of press brake. The user must wear labor protection. Before starting, carefully check the motor, switch, circuit, grounding, and the control parts and buttons of the press brake.

Run press brake idling for 1 to 2 minutes and move on the slide 2 to 3 times at full stroke. If there is anything abnormal, stop immediately to troubleshoot the malfunction.

The sheet material must be compacted when bending to prevent hurting people during bending. The power supply must be cut off when adjusting the sheet metal die. When changing the opening of the lower mold, no material is allowed to come into contact with the lower mold. When press brake works, no one is allowed to stand behind the press brake.

It is forbidden to use press brake molds to fold over-thick iron plates or hardened steel plates.

To close the press brake, place a wooden block on the lower die under the cylinders on both sides and lower the upper slide plate onto the wooden block.

How to adjust the bending angle of press brake?

Before using the press brake to bend the material, you need to adjust its various angles, including the bending force, the distance of the back gauge, the upper limit of the slider, the speed of the slider, and the adjustment of the upper and lower mold gaps.

The adjustment of the angle of the press brake is mainly to calculate the value of the bending force and indicated pressure according to the calculation formula. Then, adjust the handwheel of the overflow valve to generate the force which is slightly larger than the force of the folded plate.

The adjustment of the backgauge distance of the press brake needs to position in the length direction when bending the sheet. The button on the front button box controls the motor adjustment, whose value can be from the revolution table on the button box. There is a handwheel for fine adjustment.

The adjustment of the upper limit of the slider of the press brake needs to be realized by adjusting the position of the striker. The rising slider can stay at the required center position, which can shorten the stroke distance of the slider. It reduces the working cycle time and increases productivity.

The adjustment of the gap between the upper and lower molds in the press brake is completed by the button on the button box. Operate in the direction indicated by the press brake label. The initial adjustment gap should be greater than the thickness of the plate.

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.

How to maintain shearing machine?

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.
