using instruction of laser cutting machine
If you are user of fiber laser cutting machine, or you are going to buy fiber laser cutting machine,
maybe following infomation is helpful to you.
Water Chiller of Fiber laser cutting machine:
Question 1:What kind of water pour into chiller?
Answer 1:Water cooler inside need to add purified water or distilled water
Question 2: How long need to change water?
Answer 2:If the quality of pure water is not particularly good,
it is recommended to change the water once every 2 weeks. Good quality water, once a month for water.
Water inside do not need to add special substances.
However, if for customers, local weather is very cold,
you may need add antifreeze or industrial alcohol into the water-cooler,in order to avoid freezing.
When the weather is cold, if you do not use water chiller often , please pour out all the water timely.
Questions 3:What is the oxygen consumption of the 10 and 20 mm carbon steel laser 3000w?
In China, one bottle of Liquid Oxygen is 50$/bottle,
Standard oxygen bottle is 40L/bottle , when 3000w cut 10mm and 20mm carbon steel,
air pressure is lower, about 1-2kg, so one 40L bottle of Oxygen can be used for about 1-1.5 hours.
NOTE: For example. In China, one bottle of Liquid Oxygen is 50$/bottle,
Standard oxygen or nitrogen gas bottle is 40L/bottle
1mm Carbon steel 40L/40minutes
2mm Carbon steel 40L/50minutes
3mm Carbon steel 40L/60minutes
4mm Carbon steel 40L/70minutes
5mm Carbon steel 40L/80minutes
6mm Carbon steel 40L/90minutes
8mm Carbon steel 40L/110minutes
10mm Carbon steel 40L/130minutes
For carbon steel, The thicker metal you cut, the less Oxygen pressure you need,
because if use higher Oxygen pressure for thicker metal sheet, it will be burned.
1mm stainless steel 40L/30minutes 20
2mm stainless steel 40L/30minutes
3mm stainless steel 40L/30minutes
4mm stainless steel 40L/30minutes
Generally speaking, the thicker metal sheet, the higher Nitrogen pressure it needs.
For example, if cut 1mm ss, use 10kg Nitrogen. If cut 4mm ss, need 20kg Nitrogen.
But in order to keep high cutting speed for thin metal sheet , such as 1mm.
So we suggest client to adjust same pressure, all of them are 20kg, in this way,
it can not only make sure of high speed of cutting thin metal sheet, also it can make sure of cutting thick metal sheet.
