With the continuous improvement of plasma technology, plasma only suitable for cutting thin material is also outdated. Now, with the improvement of torch, consumable parts and power supply design, plasma system engineers can design a system with higher cutting power and thicker thickness, with a maximum thickness of over 80mm, and the system is smaller and the duty cycle higher.
Twenty years ago, some of the early hand-held plasma systems were unable to meet the requirements of the operator for cutting thicker materials. The plasma cutting machine can only cut the thin sheet. nobody to have doubt with this answer. But now you have to update the information about the CNC plasma cutting machine.
Many plasma users purchase the cutting system for first time, are used to cut stainless steel, aluminum or other non-ferrous metals. Some people still believe that the plasma system can only be used to cut these kind materials. In fact, the plasma system is very effective in cutting any conductive metal, and is the world’s most common method of cutting low-carbon steel.
From the plasma cutting method,we can see that the center temperature of the plasma arc may reach approximately 1000°C. The metal in the central area is oxidized and discolored by heat. It will affect the effect of metal processing. After cutting the stainless steel with plasma,material section may produce a certain rust residue be due to long-term placement.For this problem, many users will worry about how to deal with these rust.In fact, do not have to worry about it.Here give you two methods to remove rust.
1, after pickling must be fully washed with water and wipe, to avoid secondary pollution。You can use a manual polishing machine.Only a thin layer, it is easy to polish out.
2, for high temperature oxidation of stainless steel can be washed with stainless steel wash water, use wash water can recover the original white stainless steel.
Here’s a simple experiment:
After the high temperature baking the surface of stainless steel will become gray, black, brown, yellow, blue and iron red and other colors will gather the burning color.This color does not look good, nor has use value.Use wash water can recover the original white stainless steel.
Of course, compare with the less efficient flame cutting thin sheets,the ability of the plasma system to cut stainless steel and aluminum is one of its main advantages.In addition, the plasma system is more effective in cutting spray, dirty or even rusty steel material.These advantages make it more efficient to repair heavy equipment, cars and farm equipment.
