Precautions for purchasing laser pipe cutting machine 1: Laser power

Q: How to choose the appropriate power section equipment? Is the more power the better?

A: Generally, the appropriate power is selected according to the wall thickness of the pipe fittings

Wall thickness < 10mm, 3000W laser can meet

If the wall thickness is about 20 mm, it is recommended to choose 6000 watts

Wall thickness > 20 mm, it is recommended to choose 12000 watts

If bevel cutting is required, it is recommended to increase the power.

Precautions for purchasing laser pipe cutting machine 2: fiber laser source and cutting head

Q: In order to ensure the optical quality, how to choose the laser and cutting head of the tube cutting machine?

A: You don’t need to consider the optical quality of the lasers on the market. If you want to be on the safe side, you can choose a big brand laser.

The cutting head used for 6 kW and below is already very stable, and there is no need to choose a certain brand or model of cutting head. It is recommended to follow the advice of the equipment manufacturer for the special cutting head of the pipe cutting machine.

The shape and installation position of the cutting head have a certain influence on the use effect of the equipment. The manufacturer has selected the model of the cutting head when designing the equipment, and designed the relevant position and size of the equipment according to the size of the cutting head.

Precautions for purchasing laser pipe cutting machine 3: chuck selection

Q: What are the differences between special chucks and ordinary chucks? how to choose?

A: It is generally believed that ordinary chucks are cheap, with average accuracy and quality, while special chucks are more expensive, have higher precision, and better quality. Pipe cutting machines using ordinary chucks are generally cheaper, and the other configurations of the machine are poor, especially in places that are not seen or paid attention to.

Generally, the pipe cutting machine with special chuck is more expensive, the whole machine configuration is higher, and the equipment stability and reliability are better. If there are high requirements for processing accuracy and processing efficiency, and certain requirements for equipment quality, it is recommended to choose a pipe cutting machine with a special chuck.

Precautions for purchasing laser pipe cutting machine 4: bed selection

Q: What are the effects of the bed on the pipe cutting machine? how to choose?

A: In addition to considering the load, the bed of the pipe cutting machine needs to consider whether the structural design can meet the task requirements, because it directly affects the load capacity and cutting accuracy. The twisted and deformed bed seriously affects the accuracy and service life of the equipment. Therefore, the quality of the bed has a lot to do with the structural design, and an excellent structural design can ensure that the bed can achieve the ideal cutting effect even under a large load.

Precautions for purchasing laser pipe cutting machine 5: tail material control

Q: How to achieve the ideal effect of pipe cutting for tailing control?

A: Zero tailing and extremely short tailing are the ideal effects pursued by the processing industry. At present, only three-chuck or four-chuck pipe cutting machines can realize zero tailing cutting. The tailings below 80 mm are called extremely short tailings, which is the function of two chucks.

There are also restrictions on the realization of this function, such as: Workpieces of suitable length fill the pipe; cutting the last piece with very short tails requires less precision.

Precautions for purchasing laser pipe cutting machine 6: processing capacity

Q: How to judge the processing capacity of the equipment?

A: The processing capacity of the equipment can be reviewed from the aspects of processing pipe diameter, processing wall thickness and processing length. The size of the chuck determines the diameter of the pipe cutting machine. You can first check whether the size of the chuck meets the production needs. Fiber lasers can cut various metals and profiles without special restrictions. To judge the effective processing length and processing thickness of the pipe, it is necessary to refer to the technical plan or consult technical personnel. In fact, the most direct and effective way to judge the processing ability is the proofing test.

Precautions for purchasing laser pipe cutting machine 7: accessories configuration

Q: How important is the configuration of laser pipe cutting machine accessories? Which accessory systems can you focus on?

A: The configuration of accessories has a very important impact on the performance of the machine. The support of high-quality accessories system can add a lot to the processing capacity of the pipe cutting machine. In general, you can focus on chucks, guide rails, racks, screw rods, motors, cables, air circuits, etc. In particular, it is recommended to understand the quality control process of the equipment manufacturer. A good quality control process can make ordinary accessories perform better.

Precautions for purchasing laser pipe cutting machine 8: sample quality

Q: If the sample is not cut, does it mean that the equipment is not good?

A: You can't make such a judgment. Within the scope of laser cutting capabilities, the quality of the section does not need to be considered. If the section quality is poor, the cutting process can be adjusted. If it cannot be adjusted to a satisfactory state, please contact the manufacturer for after-sales maintenance.
