Running Cost of Laser Cutting Machines

1. Take 1mm stainless steel as an example to calculate the cost of capital and time

For example, the total production cost and approximate time cycle of 50000 meters of 1 mm stainless steel cutting (because the sheet punching time, extremely short and empty distance cannot be counted, and the production arrangement of each enterprise is different. Since it belongs to the horizontal efficiency and cost comparison, it has little impact on the comparison of statistical results, and the loading and unloading time is not included).

1. Optical fiber 2000W

50000 meters ÷ 20 meters/minute ÷ 60 minutes=41.7 hours ≈ 5 working days

41.7 hours × (27.8 yuan+70 yuan) ≈ 4078 yuan

2. Carbon dioxide 3000W

50000 meters ÷ 8 meters/minute ÷ 60 minutes=104.2 hours ≈ 13 working days

104.2 hours × (63.5 yuan+70 yuan) ≈ 13911 yuan

3. Carbon dioxide 2000W

50000 meters ÷ 6.5 meters/minute ÷ 60 minutes=128.2 hours ≈ 16 working days

128.2 hours × (50.5 yuan+70 yuan) ≈ 15488 yuan

2. Take 2mm stainless steel as an example to calculate the cost of capital and time

Example:

Production cost and approximate time cycle of 50000m of 2mm stainless steel cutting (due to the short punching time and empty distance of the thin plate, which cannot be counted, and the production arrangement of each enterprise is different. Since it belongs to the horizontal efficiency and cost comparison, it has little impact on the comparison of statistical results, and the loading and unloading time is not included)

1. Optical fiber 2000W

50000 meters ÷ 8.5 meters/minute ÷ 60 minutes=98 hours ≈ 12 working days

98 hours × (27.8 yuan+70 yuan) ≈ 9588 yuan

2. Carbon dioxide 3000W

50000 meters ÷ 4.5 meters/minute ÷ 60 minutes=185.2 hours ≈ 23 working days

185.2 hours × (63.5 yuan+70 yuan) ≈ 24724 yuan.

3. Carbon dioxide 2000W

50000 meters ÷ 3 meters/minute ÷ 60 minutes=277.8 hours ≈ 34.7 working days

277.8 hours × (50.5 yuan+70 yuan) ≈ 33475 yuan
