When using the laser cutting machine, it is necessary to pay attention to many small details and some precautions. Mastering the use skills of the laser cutting machine can make the equipment more efficient and easier to use. Next, Yida Laser will give you a detailed introduction.
In order to achieve better efficiency and cutting quality, the following laser cutting machine skills are worth learning when cutting:
1、 Corner melting; When cutting the corner of the sheet steel at a reduced speed, the laser will melt the corner due to overheating. A small radius is generated at the corner to maintain high speed laser cutting and avoid overheating and melting of steel plates when cutting corners, so as to achieve good cutting quality, reduce cutting time and improve manufacturing power.
2、 Part spacing; Normally, when cutting thick plates and hot plates, the space between parts should be large. Because the heat of thick plate hot plates has a great impact, it is easy to burn edges when cutting sharp corners and small figures, which affects the cutting quality.
3、 Leader settings; When cutting thick plates, in order to ensure good connection of the cutting seams and prevent burns at the beginning and end of the cutting process, a section of transition line, called lead line and tail line, is often introduced at the beginning and end of the cutting process The lead wire and tail wire are useless to the workpiece itself, so they should be placed outside the scope of the workpiece. At the same time, it should be noted that the lead wire should not be set at sharp corners and other places that are not easy to dissipate heat. The connection between the lead wire and the kerf shall adopt arc transition as far as possible to make the mechanical movement stable and avoid burns caused by corner standstill.
4、 Common edge cutting; Two or more types of parts share the same edge to form a combination. Large batches of regular graphics should share the same edge as much as possible. Cutting with the same edge can greatly shorten the cutting time and save raw materials.
5、 Part collision; In order to achieve high manufacturing efficiency, many laser cutting machines operate continuously for 24 hours, and use unmanned automatic loading/unloading devices to bump into the tipping parts after cutting, causing damage to the cutting head and manufacturing interruption, resulting in great losses. Note:
A. Select a suitable cutting path, bypass the cut parts, and reduce collisions.
B. Select a good cutting route to reduce cutting time.
C. Automatically or manually combine multiple small parts with tiny connections. After cutting, the removed parts can easily disconnect the tiny connections.
In order to achieve a better operating state of the laser cutting machine, regular maintenance is also essential. The following points should be paid attention to in the maintenance of the laser cutting machine:
1) Check the straightness of the track and the perpendicularity of the machine every six months, and timely maintain and debug in case of any abnormality. Otherwise, the cutting effect may be affected, the error will increase, and the cutting quality will decline.
2) Check the steel strip frequently to ensure that it is tight. Otherwise, if there is a problem in the operation, people may be injured. The steel belt looks inconspicuous, but when it goes wrong, it should not be underestimated.
3) Use a vacuum cleaner once a week to remove the dust and dirt in the machine, and all electrical cabinets should be tightly closed to prevent dust.
4) All guide rails shall be cleaned regularly to remove dust and other sundries to ensure normal operation of equipment. The rack shall be wiped frequently and lubricated to ensure lubrication without sundries. The guide rail and motor shall be cleaned and lubricated frequently, so that the machine can move better and cut more accurately when moving, and the quality of the cut products will be improved.
5) The double focus laser cutting head is a vulnerable item on the laser cutting machine. Long term use may cause damage to the laser cutting head.
