Plasma cutting machine processing error analysis
In the current domestic market, there are many plasma cutting machine manufacturers are advocating their own CNC cutting machine configuration is how high, misleading customers need to add CNC cutting machine into a high configuration of equipment, such as the replacement of imported CNC system, imported height, etc. , but the import configuration can only be said to make the machine more stable and durable, do not fail, for the machine's cutting accuracy is not much impact. Because no matter the CNC flame cutting machine or CNC plasma cutting machine, due to the cutting width by the cutting mouth and other factors, no matter how high the accuracy of the equipment itself, with the accuracy of the parts cut out, the error is generally about ±0.5mm, the error is several orders of magnitude higher than the equipment itself. That is, or with millions of large imports of CNC cutting machines, can only be so. This is the CNC flame cutting machine or CNC plasma cutting machine cutting process decided, in any case, can not get the same high processing accuracy as other CNC equipment such as CNC crib. That is to say, the accuracy of the device itself is level 6 or 8, it is not very important.
Generally speaking, CNC plasma cutting machine in the realization of non-linear cutting processing, need to be through the control system and plasma power supply to achieve a better cutting quality effect, due to different from the conventional straight-line cutting processing, in the use of techniques and plasma cutting machine power supply selection has a lot of details worthy of our consideration and attention, this article by the cnc cutter limited / meisar technical department through the actual inspection, the use of the United States Hypertherm 45A air plasma power supply processing relevant technical points.
In the comparison of various cutting methods of CNC cutting machine, many users will simply understand that plasma cutting has advantages over flame cutting, especially in the quality and precision of cutting processing performance. Of course, after the real contact with the two types of cutting processing, we can obviously find that, in fact, whether plasma cutting or flame cutting, there is no difference in processing errors, and the causes of the above-mentioned cognitive misunderstanding is also a variety of reasons, such as users will be based on the acquisition cost of CNC plasma cutting machine and judge the cutting quality is better; So many more reflect the domestic user enterprises for CNC plasma cutting machine understanding bias.
The elliptical plasma arc of the CNC cutting machine will form a certain angle tilt because of the elliptical arc surface, in practice, according to different processing needs we need to understand how much this tilt angle, in order to determine whether the cut out of the material can meet the secondary processing requirements. In the past research and practice, the technical department of Garpide found that the tilt angle and cutting material of the CNC plasma cutting machine and the quality of the plasma power supply used are related. For example, when using CNC plasma cutting machine to cut aluminum, titanium alloy and other soft metal, its roughness is poor, cutting surface is not complete, and when cutting carbon plate roughness is basically equivalent to flame cutting the same as 25um, but the tilt angle is larger. The cut surface roughness of different types of plasma power supplies is slightly different, and the use of different cutting gases can also affect the cutting roughness. Plasma cutting on the speed adjustment, cutting height and other requirements are higher, easy to leave cutting slag, hanging slag in the unmosted metal content than flame cutting more, relatively difficult to remove a little.
From the point of view of production efficiency, the speed of cutting, to CNC flame cutting machine cutting as an example, completely depends on the thickness of the plate, cut mouth model, oxygen purity, gas quality and other factors, the speed of movement of equipment should meet and adapt to the requirements of the cutting process. In other words, there is no direct relationship between cutting efficiency and the equipment itself. Of course, CNC cutters still embody considerable precision and efficiency, but this is relative to manual cutting, with the commonly referred to machine tool processing accuracy and efficiency improvements, not a concept.
So what is the plasma cutting machine processing error of the import cutting system? What is the difference between the cutting performance and the traditional cutting method? <br />
Hypertherm Powermax45 series power supply for the United States Hypertherm air plasma cutting machine system the least powerful one of the products, its lightweight and simple design has been praised by many thin cutting enterprises, Powermax45 (only 17kg) is mainly used for handheld and machine cutting, in low operating costs, providing unparalleled portability, high productivity and reliability.
The Powermax45 single gas system (air or nitrogen) cuts materials up to 19mm thick and has a cut-off capacity of 25mm. It is suitable for cutting and plowing metals in a variety of industries, such as HVAC pipe cutting, truck and trailer manufacturing, and maintenance of various types of equipment, including manufacturing and agriculture.
The Powermax45 cuts three times faster than conventional cutting systems such as flame cutting and delivers superior cutting quality and higher yields at low operating costs. Unlike flame cutting, plasma systems do not require flammable gases to be adjusted, making them safer and easier to use. It also does not require warm-up, which increases effective cutting time. The Powermax45 is not only low cost but also productive. With a high power/low weight ratio, technology provides up to.
50% load rate, fast cutting and high-quality slag-free cutting performance. This minimizes rework rates or eliminates the need for secondary processing. Heat treatment systems feature more efficient cooling of internal components for greater reliability.
