For a long time, many people are struggling to buy second-hand laser cutting machines. Will there be hidden dangers? Next, let's take a look with Pentium laser.
1. First, learn about the core components of the laser cutting machine, fiber laser, cutting head: servo motor: chiller: air supply system: host: control system, regulated power supply: the core components of the machine assembly. All machines have a certain service life. When the service life is exceeded, these core components are aging and prone to failure.
For example, there is slag in the cut-out, the cut-out is not round and smooth, the cut-out is not transparent, the power is attenuated, the machine does not produce light, the water enters and so on. There is not only one place to repair. If the cutter is broken, you can only find the manufacturer to repair this large object.
2. After sales service
When you choose a second-hand model, the problem will come. What can you do without after-sales service when there is a problem with the machine? Do you need to go back to the manufacturer for maintenance? For a complete laser cutting machine, replace the laser, replace the cutting head and other core components, and the added money can also buy a new one. Moreover, the maintenance costs of different manufacturers are different, and field investigation is required. Therefore, when you want to choose a second-hand cutting machine, it is recommended to consider after-sales service.
3. Overall structure process level
Attention should be paid to the overall structure and process level of the laser cutting machine. Now the cutting range is more and more extensive, which is a test for the overall structure of the cutting machine. At the same time, the product process needs to be improved to be competent for more difficult work. Therefore, both the overall structure and process level need higher requirements. The second-hand cutting machine is completely different from the new one in terms of process and equipment, and the technology is constantly innovated every year, Maybe you think that saving money by buying second-hand goods is actually a waste of money.
4. Cost performance
When choosing products with high cost performance, you should look at the scope of application and the working intensity of the machine. Of course, the price of new equipment is also sinking. It is better than the old equipment in terms of service cycle, structure and function, and the accuracy and maintenance cost are much better than the old equipment. In general, when choosing laser cutting machines, you should know whether to buy new or second-hand ones.
