Compare the cost of various types of laser cutting machine
1 to1mmStainless steel as an example to calculate the use of capital and time costs
For example:The cumulative production cost and approximate time period of 50000 meters for cutting 1mm stainless steel (because the punching time and short and empty range of thin plates cannot be counted, and the production arrangement of each enterprise is different, due to the comparison of horizontal efficiency and cost, the comparison of statistical results has little influence, and the loading and unloading time is not counted)
1Fiber 2000W
50000Meters÷ 20 m/min ÷ 60 minutes = 41.7 hours ≈5working day
41.7 hours ×(27.8 yuan, 70 yuan) ≈4078Yuan
2Carbon dioxide 3000W
50000Meters÷ 8 m/min ÷ 60 minutes = 104.2 hours ≈13working day
104.2 hours ×(63.5 yuan, 70 yuan) ≈13911Yuan
3CO2 2000W
50000Meters÷ 6.5 m/min ÷ 60 minutes = 128.2 hours ≈16working day
128.2 hours ×(50.5 yuan, 70 yuan) ≈15488Yuan
2 to2mmStainless steel as an example to calculate the use of capital and time costs
For example:The cumulative production cost and approximate time period of 50000 meters for cutting 2mm stainless steel (due to the short punching time and empty range of thin plates and the inability to be counted, and the different production arrangements of each enterprise, due to the comparison of horizontal efficiency and cost, the comparison of statistical results is not significant, and the loading and unloading time is not counted)
1Fiber 2000W
50000Meters÷ 8.5 m/min ÷ 60 minutes = 98 hours ≈12working day
98 hours ×(27.8 yuan, 70 yuan) ≈9588Yuan
2Carbon dioxide 3000W
50000Meters÷ 4.5 m/min ÷ 60 minutes = 185.2 hours ≈23working day
185.2 hours ×(63.5 yuan, 70 yuan) ≈24724Yuan
3CO2 2000W
50000Meters÷ 3 m/min ÷ 60 minutes = 277.8 hours ≈34.7working day
277.8 hours ×(50.5 yuan, 70 yuan) ≈33475Yuan

Operating costs of laser cutting machines
Cost of laser cutting machineMainly includes power consumption, auxiliary gas costs and wearing parts.
Take 500W fiber laser cutting machine as an example:
1. Power consumption: The power consumption of 500W fiber laser cutting machine is 6 degrees per hour, and the cost of electricity is about 6 yuan/hour (calculated by 1 yuan/degree).
2. Auxiliary gas consumption:
Oxygen: 15 yuan/bottle, about 1 hour, unit price 15 yuan per hour
Nitrogen: 320 yuan/can, about 12~16 hours, unit price per hour 20 yuan.
Note: In this article, oxygen refers to bottled. Nitrogen is cheaper to fill than bottled, and it also saves the time for operators to ventilate and the waste caused by excessive bottled residual gas. In addition, gas prices will vary in different regions.
3. Consumption of other vulnerable parts:
Protective lens: normal use for more than 300 hours, the price of 150 yuan/piece, about 1-2 yuan per hour
(If the working environment is good, the use time will be longer)
Copper mouth: normal use for more than 300 hours, the price of 50 yuan/piece, about 0.18 yuan per hour
Ceramic ring: normal use for more than 7200 hours, the price of 400 yuan/piece, about 0.11 yuan per hour
