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
