Whether you are a buyer for the first time or existing systems, plasma and / or oxy-fuel cutting systems form, continued advances in technology and a landscape increasingly low-cost manufacturers and integrators obfuscated form of automated Landscape plasma cutting machines.
Plasma cutting is the result of the introduction of an electric arc through a gas that is blown through a nozzle at high pressure, thereby producing the gas in a plasma flame, producing a concentrated,reaches temperatures of 50,000 degrees Celsius. Automated plasma cutting are either conventional or precision (high definition) classified according to the characteristics of flame cutting. Precision-plasma systems are able to share closer tolerances to achieve faster rates of lower interest and produce less cutting and bevel than conventional plasma. The cost of these devices can be significantly higher even than conventional plasma. E 'therefore veryimportant to correct the shape-cutting machine with the corresponding plasma cutting machine.
One of the most common and costly pitfalls buyers occurs when manufacturers and integrators mismatch machines or sources of energy. This is often the result of not producing the time to understand the needs of the buyer that a limited product line or machine, OEM limited access to sources of energy and / or lack of industry / application of knowledge. These producersthey sell it too often with a focus on lowest price rather than lower costs, highlighting the strength of the plasma system or machine, without regard to the limits of the other. The best source of precision plasma power is available to any user with the desired cut quality and accuracy, if not plugged into a machine suitable base.
There are many types of plasma cutting machines shape the market today. The most common machines or bridgeHome-style machines made of steel or aluminum. The construction of the machine is extremely important in relation to your application. Machine aluminum are generally built as hobbyists or artisans and machine especially when doing a limited number of cutting or cutting of lightweight materials so far. The plasma and oxyfuel cutting processes generate large amounts of heat that is retained in the cut and materials can causeBending or distortion of the moving mechanical parts in aluminum during the hot-sectional areas, causing too much precision and cut quality. Prefabricated steel machines are highly recommended for any type of continuous cutting, the cutting of sheet steel and can help where oxyfuel burners are used. Auxiliary heat shields may also be available to further protect the machine components from extreme heat.
Cutters are available with a variety of drive systemsthe drive including a one-sided, single-engine double-sided driving, double sided with two motors drive systems. A well-developed system of traction on one side or single-engine, dual-side-drive system is very good at conventional plasma applications. The advantage of the additional accuracy provided by two double-sided motor drive systems will not be realized in conventional plasma applications because of limitations in the accuracy of conventional plasma cutting themselves. Two dual-side enginesDrive systems offer the performance and accuracy required for optimal results of a plasma process precision.
Sizing of engines and transmissions based on the weight of the machine is very important. For small engines and transmissions in the degree of effectiveness of mass in the machine direction and cross cutting speed, the angles in which non-uniform, quality of cut and washed. This not only affects the quality of the cut, but also causepremature mechanical failure.
The control is unity, that connected all the functions and characteristics of the source drive and plasma. Basically there are two classes of checks at most of these machines in use today. Most industrial applications, industrial PCs, control systems, as they are produced by Burny and Hypertherm. These units are user-friendly touch screen control panels are in enclosures that can withstand the harsh environments in which they operate housedin the smaller machines of hobbyists or artisans types often use standard PC boards with I / O control units and plasma systems. Industrial controls are highly recommended for all applications, are designed for industry specific requirements that are less vulnerable to problems typical PC, but can be expensive in small applications.
Another important and often overlooked, is to contribute to the selection of a machine is the construction of the railway system. Plasma cuttingProducing machines and are in a difficult environment. It 'important that the components used in the construction of robust rail system enough to survive in this environment. All surfaces must be constructed of materials by rail hardened and cleaned frequently so that it will not stoned and stabbed by splashes of molten steel, which will inevitably fall on them. Self-cleaning wheels are also a feature recommended to clean the wheels of regular preventiveMaintenance (PM) cycles. Sizing guides should be robust enough to avoid displacement, the machine moves over them.
Combining all the above factors results in the precision and accuracy of the system. Unlike other methods of machining, it is difficult to assign a default tolerance of the process of plasma cutting. Many manufacturers will be strengthened by the fact that their aircraft position accuracy of + / -0.007 inches and repeatability of + / -0.002 inches have.The fact is that almost every machine on the market tolerances can withstand a lot about tolerance and the ability of the plasma process itself. There are many factors that influence the quality of the cut made by the parties including: the properties of the component, power management settings, supplies, gas, material type, thickness / strength of the material, the layout on the plate, and so on. Ask the seller to cut you with samples of your parts or parts that provide tightBring the parties want to cut that has a machine / plasma combination, which is comparable to what you're looking for. This gives you the realistic representation of what to expect from my computer / plasma combination, and the plasma-cutting per se.
Prior to identify each manufacturer of cutting machines clearly your needs:
Identify the types of materials you will use your system (ferrous / non ferrous metals, steel, stainless steel can be cutSteel, aluminum, etc..) Identify the range of thickness of the material you are cutting. If you are cutting a wide range of materials and thicknesses to estimate the contribution of each species and to identify the primary types and thicknesses. Determine the size (length, width and thickness) of the plate you are buying is to correct the size of your board, effective cutting area and load the new system. You might also want to look to the future on holdall types and sizes of future materials need to process. To anticipate the costs in advance, these requirements can be much lower than retrofitting or upgrading your system in the future. Identify the tolerances must be maintained. This will help if you have a plasma system, the conventional, precision, and the nature and structure of the base machine. Determine how many hours per day and days per week operated machine. This isdetermine the type of basic engineering require the estimate of operating costs and allow the cost / benefits of life consumables will compare different manufacturers of power supplies. Determine how to exhaust your devices. Aquifers do not require exhaust systems, but not barrel tables. If there is an existing drainage system in place to identify the system's capacity in cubic feet per minute (CFM). Determine whether you need the flexibility toexpand the system or additional plasma / oxy-fuel stations or in the future. Some machines can contain only one or two torches, while the other slave stations can accommodate up to a combination of plasma and oxyfuel burners 10. In addition, some machines have set the cut surface, while others can be expanded in length, increase the mean field or place several cutting tables. Define the area of your structure, where the machine is located. Write down allObstacles, hazards or access points should be considered the interpretation of the new system. Also find out how your material will be treated on and off the field (forklift or crane, power sites, etc..) Identify the power you have available, both voltage and current.
A reputable manufacturer, you should ask for most of this information before you have any suggestions for a system. If a producer does not have this information, they can not adequatelyAssess needs and propose a system that is best for you and your specific application functions. The expenditure of time, identify the requirements in advance will not only save many hours of frustration, you save the life with the wrong car, but money is not over-or under-purchase of a system to suit your specific applications to meet the .
