Four hidden dangers of buying second-hand goods
1. First, learn about the core components of the laser cutting machine, fiber laser, cutting head: servo motor: chiller: gas supply system: host: control system, regulated power supply: the core components of the machine assembly. All machines have a certain service life. When beyond the service life, 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 emit light, water and other problems, and the maintenance is not just one place. 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 one, then the problem will come. When there is a problem with the machine, what can you do without after-sales service? Is it necessary to find a manufacturer again for maintenance? For a complete laser cutting machine, replace the laser, replace the cutting head and other core components, and the sum of money can also buy a new one. Moreover, the maintenance costs of different manufacturers are different, so you need to make field visits. Therefore, when you want to choose a second-hand cutting machine, it is recommended to consider after-sales service.
3. Overall construction 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, whether from the overall structure or process level, higher requirements are required, while 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 it's a waste of money to save money by buying second-hand ones.
4. Cost performance
Choose products with high cost performance. When choosing products, 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 and structure and function. The accuracy and maintenance cost are much better than the old equipment. In general, when choosing laser cutting machines, you should be clear about whether to buy new or second-hand ones.
