When operating a laser cutting machine, it is inevitable that the cutting quality will be very poor. Today, Quanrui Technology introduces a common laser cutting problem: cutting discontinuity.
Reasons for cutting discontinuities
Improper programming may cause discontinuities in template cutting. The cutting head is very close to the surface of the workpiece during the cutting process. When cutting multiple parts of the steel plate, the laser program defaults to scribe first and then cut to avoid the cutting head colliding with the cut off metal piece, which makes the cutting head and the machine unnecessary. Damage. If the closed area is not closed when the laser program is compiled, the local steel plate is connected to the whole after cutting, and manual cutting can easily damage the model and cause scrap.
The ventilation of the auxiliary gas during the laser cutting process will also cause the discontinuity of cutting. During the processing, the auxiliary gas mainly blows the molten metal out of the slit. When the auxiliary gas is used, the equipment automatically stops moving and waits for the gas replacement to continue. Cutting, so the trajectory of the cutting is slightly different from the trajectory when parking, resulting in discontinuity in the cutting trajectory.
How to avoid cutting discontinuities
1. To solve the problem of laser cutting discontinuity, we must solve the cause of cutting discontinuity. The cutting discontinuity caused by programming errors requires designers to have high professional quality. In the process of preparing the cutting program, we must carefully check to avoid error.
2. For the cutting discontinuity caused by replacing the auxiliary gas, after accumulating actual operating experience, when changing the gas bottle to re-cut, we need to reduce the cutting speed to 5% of the normal cutting speed, and press the start key and Speed increase key to continue cutting.
3. When the laser cutting machine is stopped suddenly and restarted during the work, the cutting point interface will also be discontinuous. Therefore, it is necessary to strictly follow the instructions in actual work to prevent the cutting machine from stopping due to incorrect operation.
Regardless of whether it is carbon steel, stainless steel, or titanium alloy materials, the continuous cutting trajectory can be achieved through these methods, so that the workpieces are completely connected, with high accuracy and quality.
Fiber laser cutting machine has high flexibility, fast cutting speed, high production efficiency, and short product production cycle. Whether it is simple or complex parts, you can use laser to achieve a rapid prototyping and cutting at the same time, its operation is convenient, low cost, and cutting effect. It is also very good. It is precisely the fiber laser cutting machine that has such a unique advantage that allows laser processing equipment to enter the road of rapid development. It is also because of the addition of laser cutting technology that China's sheet metal processing industry can be more and more it is good.
