Why is it not recommended to purchase a second-hand laser cutting machine?

1. The lifespan of the fiber laser is lost, the laser power decreases, and the cutting efficiency decreases. Laser, as one of the core components of laser cutting machines, is very expensive. The laser power of a laser cutting machine that has been used for a long time will gradually decay. If this laser cutting machine is used for a long time, the laser power may weaken significantly. If the laser power decreases, the cutting thickness decreases, and the cutting speed will also decrease accordingly. The cost of replacing the laser is significant.
2. CNC machine tools have fast functional updates and outdated second-hand equipment, which is not conducive to fine machining in the later stage.
3. After sales service is virtually non-existent, and if there is a malfunction, the original factory cannot be contacted. The warranty period for most second-hand laser cutting machines has expired. If there are problems outside the warranty period, buyers generally cannot directly contact the original factory. The laser cutting machine manufacturer is not aware that the equipment they sell has been transferred, and there is no way to provide accurate after-sales service judgment and repair. If parts need to be replaced, the maintenance cost is very high, which is very detrimental to the buyer.
4. Incomplete accessories affect cutting progress. When general customers purchase new equipment, the seller will deliver a large number of vulnerable parts, accessories, etc., such as nozzles with different diameters, ceramic rings, protective lenses, etc. But if you directly purchase second-hand laser cutting machines, these accessories are generally not available, which invisibly increases the cost for customers to use second-hand laser cutting machines.
