The precision of a plasma-cut edge is getting close to perfect. Plasma used to deliver rough and unclear cuts, but nowadays a shiny and reflective edge can be created. To achieve this precision, HGG has done a lot of research. We have listed the most important factors for you.
To achieve more precision, HGG specifies the following ingredients:
In however which way these are combined influences the cut in quality, speed, mileage per gas, and finally the economic value for every cut.
As an example: plasma tapers acquire up to 1 degree in tapers, but HGG manipulates the torch to achieve perfectly square edges.
1. Choosing the correct gas for the job
Mild Steel: O2 / O2 and O2 / Air
Stainless steel: F5/N2 and H35/N2
2. Choosing the correct nozzle
When cutting profiles always choose a nozzle were the thickness of the profile is in the middle or lower part of the cutting table.
When applying an angle during cutting the length will increase if the length goes outside of the table (range of the nozzle) cutting quality will decrease or the nozzle might not be able to penetrate the material completely.
3. The cutting direction
HGG machines optimizes cutting direction making sure the cut part is always on the good side of the plasma beam.
4. The cutting speed
HGG machine automatically adjust speed based upon the current cutting length this ensures plasma beam is always moving at the correct speed to get the best cut quality.
Consumables wear as they are used and will eventually start to affect kerf width and edge quality. Making sure that consumables are changed in time will make sure you always deliver the best part quality to your customers.
