The power consumption of laser cutting machines mainly includes several aspects (I refer to high-power metal laser cutting machines)
1. Laser generator (depending on the power of the generator, generally a 2000W generator should be around 30KVA. A 4000W generator should be around 50KVA, and the higher the power, the greater the power consumption)
2. The mechanical part (including servo system, NC, and electrical components, which depends on the power consumption of the cutting manufacturer's designed motor size, etc.) generally needs to be above 10KVA
3. Water cooling machine (used to cool the optical path and generator, the water cooling capacity should also match according to the power of the generator. Generally, it also needs to be above 20KVA)
4. Air compressor (the power size of the air compressor varies among cutting machine manufacturers, and it should be at least 5KVA or above)
5. Some manufacturers also have additional dust removal devices. Overall, for example, the one hour high power consumption of a 2000W cutting laser is 65KVA, approximately 50 degrees Celsius. Of course, laser cutting machines cannot always be running at full power. Generally, they require 30 to 40 degrees of electricity at a 70% discount. Calculated at 1 yuan/degree of electricity, the power consumption of a 2000W metal laser cutting machine is 30 to 40 yuan per hour.
