韩国采购需求：激光切割机、激光雕刻机、激光焊接机、激光清洗机、激光打标机、光纤激光机

We are looking for a laser cutting machine with specifications similar to our previous model. Key requirements include a 2000W fiber laser source, a working bed size of 600x600mm, and compatibility with both nitrogen and oxygen gases. It's important that the laser head has automatic focusing capabilities, similar to known brands in the market. Additionally, we require a robust control system, preferably with advanced servo motors and drivers, coupled with a reliable cooling solution. The system should operate efficiently under a temperature range of 0-45°C and humidity levels from 5-95%. We're also keen on high-quality guide rails and precise transmission systems. Please share any suitable options that meet these criteria.
