For a long time, many people have been struggling to buy second-hand laser cutting machines. Jiatai tells you with many years of production experience that there are four hidden dangers in buying second-hand laser cutting machines
- First of all, let’s 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 they exceed the service life, these core components are aging and prone to failure
For example, there is slag in the cutting, the cutting is not round and smooth, the cutting is not thorough, the power is attenuated, the machine does not emit light, the water enters, and so on. The maintenance is not just one place. If the cutter is broken, you can only find the manufacturer to repair this large object. - After sales service
When you choose a second-hand model, then the problem will come. When there is a problem with the machine and there is no after-sales service, what should we do? Is it necessary to find a manufacturer again to repair a complete laser cutting machine? If you replace the laser, the cutting head and other core components, you can buy a new one with the added money. Moreover, the maintenance costs of different manufacturers are different, and field visits are required. Therefore, when you want to choose a second-hand cutting machine, it is recommended to consider after-sales service. - Overall construction process level
We should pay attention to the overall structure and process level of the laser cutting machine. Now the scope of cutting is becoming wider and wider, which is a test for the overall structure of the cutting machine. At the same time, the process of the product needs to be improved to be competent for more difficult work. Therefore, both the overall structure and the process level need higher requirements. The second-hand cutting machine and the new one are completely different in terms of process and equipment. Every year, the technology is constantly innovated, Maybe you think it’s expensive to save money by buying second-hand ones. - 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 the 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 the laser cutting machine, you should have a clear idea whether to buy a new one or a second-hand one.
