By definition, steel is extremely strong and difficult to cut. Fortunately, there are several technologies and machines that have been specifically designed to cut and shape all grades and thicknesses of steel. High definition plasma machines (or high definition plasma) are one of those technologies that offer incredible precision and efficiency when cutting mild steel, stainless steel and aluminum.
Fundamentals of plasma cutting
Plasma cutting is a process that involves blowing a gas (oxygen, air, inert and others) at high speed out of a nozzle, while at the same time sending an electric arc through the gas into plasma. The plasma is hot enough to cut metal and moves fast enough to move molten metal away from the cut. A high precision plasma system concentrates more energy in a smaller area, and a higher plasma density creates a precision cut with a narrower cut, less rounding at the top edge and less bevel
High definition plasma (also known as HD plasma, CNC plasma and high-density plasma) is the latest in plasma cutting technologies, in which the plasma arc is forced through a smaller nozzle to achieve edges of Cut squarer and cleaner, while obtaining acceptable parts. Life in the torch.
A supplier of plasma cutting systems can help manufacturers determine the characteristics of the equipment that make sense for their applications. Use the following features to evaluate the cutting quality of the test pieces and remember to ask the plasma system vendor the cutting time and the estimated cutting cost per piece for those test pieces:
A quality cut produces a part that is ready for the next manufacturing step. Features include a smooth slag-free surface and nitride contamination.
Rounding of the upper edge is caused by the heat of the plasma arc on the upper surface of the cut. Proper control of the torch height minimizes rounding of the upper edge.
Cutting too fast or using a torch that is too high causes higher splashes, which is easy to remove.
Easy to remove slag indicates that the cut is too slow. Hard to remove slag indicates that the cut is too fast.
The cutting width (or cut) is related to the hole size of the tip, the current configuration and the torch height.
Cut the bevel angle of the surface. High precision processes produce a bevel angle of 0 to 3 degrees, while conventional plasma produces larger bevel angles. Proper control of the torch height produces the smallest bevel angle (as well as the cutting width and rounding of the upper edge).
When carbon steel is cut with air as plasma gas, some of the nitrogen is absorbed on the cutting surface, which requires grinding before welding to eliminate porosity and the risk of nitrides at the grain boundary.
This cost-effective and efficient method of High-Definition Plasma Cutting produces products of moderate quality and accuracy. Fast Flame Profiling has High-Definition Plasma Cutting Services with bed sizes of 13000×3000.
