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

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

(1) optical fiber: 2000W

50000 m ÷ 20 m / min ÷ 60 min = 41.7 hours ≈ 5 working days

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

(2) carbon dioxide: 3000W

50000 m ÷ 8 m / min ÷ 60 min = 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

For example: the cumulative production cost and approximate time period of 50000 meters of stainless steel cutting 2mm (because the sheet punching time and empty distance are extremely short and cannot be counted, and the production arrangement of each enterprise is different, it has little impact on the comparison of statistical results because it belongs to horizontal efficiency and cost comparison, and the loading and unloading time is not included)

(1) optical fiber: 2000W

50000 m ÷ 8.5 M / min ÷ 60 min = 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

3、 Operating efficiency (taking 1-4mm thickness as an example)

Operating cost of laser cutting machine

The cost of laser cutting machine mainly includes power consumption, auxiliary gas cost and vulnerable parts.

Take the 500W fiber laser cutting machine as an example:

1. Power consumption: the power consumption of 500W fiber laser cutting machine is 6 kwh per hour, and the cost of electricity is about 6 yuan / hour (calculated by 1 yuan / kWh).

2. Auxiliary gas consumption:

Oxygen: 15 yuan / bottle, about 1 hour, unit price per hour: 15 yuan

Nitrogen: 320 yuan / tank, about 12-16 hours, and the hourly unit price is 20 yuan.

Note: oxygen in the text refers to bottled; Nitrogen filling saves costs compared with bottled ones, and also saves the time for operators to change air and waste caused by excessive bottled gas. In addition, gas prices in different regions will be different.

3. Consumption of other vulnerable parts:

Protective lens: for normal use of more than 300 hours, the price is 150 yuan / piece, about 1-2 yuan / hour

(if the working environment is good, the use time will be longer)

Copper mouth: normal use for more than 300 hours, price 50 yuan / piece, about 0.18 yuan / hour

Ceramic ring: for normal use of more than 7200 hours, the price is 400 yuan / piece, about 0.11 yuan / hour
