After the COVID-19 broke，competition in the laser processing industry is more intense. Most users are very concerned about how to improve efficiency and reduce costs.This article takes processing time and processing object as control variables, and takes 3000w, 6000w, 8000w, and 12000w fiber laser cutting machines as examples to comprehensively analyze the cost of different power machines under different conditions.
As it is known to all, it is general to cut medium and thin metal plates with low and medium power (1500w 3000w 6000w) fiber laser cutting machine， and it is more advantageous to use high power(above 8000w) fiber laser cutting machine to cut thick plates. But if you use ultra-high power（above 12000w） instead of medium power(above 8000w) laser cutting machine to cut thin plates, the cost will be higher.
In fact, the cost analysis of laser cutting on the Internet above is only based on theory, and there is no actual data support. On the contrary，the following conclusions are drawn by the GLORYSTAR team after a lot of actual testing and data analysis.
The first thing to talk about is time cost, arguably the most important of all costs. Time cost as the core competitiveness of the metal processing is directly related to the customer's delivery date.
The picture above shows the speed performance of using different power laser cutting machines to cut different thicknesses of stainless steel.It is obvious that the cutting speed of 8000w laser cutting machine and 12000w laser cutting machine is leading.
The following are representative data of different power fiber laser cutting machines
For cutting 8mm stainless steel ,it takes 10 days to cut with a 12000w laser cutting machine and takes 15 days to cut with a 6000w fiber laser cutting machine. Under the same conditions,the lead time for cutting with 8000w laser cutting machine is 10 days, and the lead time for cutting with 3000w laser cutting machine is 1 month!

In addition, it cannot be ignored that the effect for cutting with 8000w & 12000w fiber laser cutting machine is much better than that with 3000w & 6000w fiber laser cutting machine.
The time cost has already been mentioned above，the following will start from the processing cost，including electricity,auxiliary gas, consumables and so on.Because there is too much data, the results will be discussed directly below instead of listing specific data.
Note: The electricity fee here is calculated at $0.16/kw·h
Still taking the example of cutting 8mm stainless steel mentioned above to calculate how long it takes for cutting the workload of an 8000w fiber laser cutting machine for 10 days (20H per day) with different powers fiber laser cutting machine.
Taking the example of cutting 4mm stainless steel below, which is currently in demand in the metal processing market.（Same restrictions as above）
After testing, we concluded that 8000w and 12000w laser cutting machines have the lowest overall cost wider processing range and better cutting quality. Time cost and electricity cost are both saved by more than 70%. For customers who already have low- and medium-power fiber laser cutting machines, the most direct way to improve efficiency and reduce costs is to purchase high-power fiber laser cutting machines.For customers who already have low- and medium-power fiber laser cutting machines, the most direct way to improve efficiency and reduce costs is to purchase high-power fiber laser cutting machines.If you plan to enter the metal processing industry but have not purchased a laser cutting machine，we recommend choosing a medium power fiber laser cutting machine，which not only can guarantee the processing range, but also control the processing cost.
Last month, we visited Leonard who purchased a 12000w laser cutting machine in the first half of this year. Before that, he had already bought two 3000w and a 6000w fiber laser cutting machines. He welcomed us and told us about the usage of the newly purchased machine. He also told us that the purpose of buying a new high-power machine at the beginning was only to cut thicker materials to expand the processing business, but he did not expect it to bring him a lot of surprises.
Before, a company occasionally sent a batch of 8mm stainless steel plates to Leonard for processing. It was coincidental that this 12000w new device has just been assembled, so Leonard immediately put it into use.On the first day , he discovered that the processing speed of the 12000w laser cutting machine was much faster than that he expected，the final delivery time has been exactly advanced by half.
When receiving the message that the processing was completed in advance, the supplier thought that this batch of materials had not been processed in accordance with his requirements, because it would not be possible to complete it so quickly at the usual speed. But when he saw the finished product with better processing effect, he immediately decided to cooperate. Since then, many companies have established long-term cooperative relations with them. Leonard plans to buy another 12000w fiber laser cutting machine this Christmas. The most direct reason is that since the 12000w laser cutting machine was put into use, orders have been increasing. He also told us that a 12000w fiber laser cutting machine processing efficiency is equivalent to two sets of 6000w processing efficiency with better cutting quality and lower labor costs.
