Plasma cutting machine with CNC. Machines and equipment

The companies used different methods of cutting metal. Be this operation by mechanical means, using gas, laser, etc. But the most effective technology for cutting is plasma. With the use of this technique it is possible to cut metals and alloys of virtually all types. At the enterprises of the cutting of such materials is made on special machines. Because the plasma cutting of metal began to be used in industry not so long ago, all machines of this type have a modern design and in most cases equipped with CNC.

Scope

Most machines of this variety are installed at the enterprises engaged in mass production of parts. Ease of use for the production in continuous mode the huge number of the same workpieces such equipment is due to presence in its design of the CNC. After all, once is enough to develop the project products to enter its parameters in a special software, and the unit will operate in a given mode as long as necessary.

Main advantages

The benefits of equipment such as plasma cutting machine CNC, among other things, include:

• High accuracy of cutting. Errors maintained equipment, controlled by computer, to make simply not could.
• Perfect repeatability of the position of all faces and sizes can be produced. This is especially useful in case if the parameters of finished products are regulated by GOST.
• High-speed cutting. Machine plasma CNC cutting machine can be equipped with several working tools. At the same time during the operation of the machine, all necessary for manufacturing the specific details of the cutters act simultaneously.
• Clean cut. Since the edges of the cut sheets remain smooth, eliminating the need for additional processing.

Have such equipment and one significant advantage compared to conventional. To work on it much easier. Because all that happens is that the operator of such a machine — is to follow the continuity of the process and the quality of manufactured products.

Features of the design units

CNC plasma cutting Machine can have different performance, dimensions and packaging. But the major subassemblies of any of such units are:

• Torch-a plasma torch;
• Power supply
• A device designed to move the cutter or part;
• Table;
• NC.

Consumables for plasma cutting on these machines, if necessary, can be purchased separately or in kits. Change the units of such units is usually in the case that deteriorates the quality of the cutting, the burn box on the end of the electrode or deform the wall of the nozzle.

Kinds of machines

To be Classified CNC plasma cutting machine can according to the following criteria:

• Design. In this respect, distinguish units, portable and stationary.
• The Number of processed sheets. Are used in the production of one-, two - and multi-units of this type.
• The method of placing the sheet. Plasma cutting machine with the CNC system can be cantilever-gantry, articulated or gantry type.
• The type of the processed products. Such equipment can be used for cutting sheet metal, pipes and so on.

Types of plasma cutting

Burner on the machines of this type can be used different. So, for example, cutting often produces jet direct action. Such plasma torches are called axial and they have a very high efficiency. Also sometimes used burners, the use of which the arc occurs between the nozzle and cathode. This type is usually used for cutting very thin metals or non-conductive materials has a low index of thermal energy.

Depends on the design of the plasma torch of the machine and the applied cutting technologies. Very often, cutting is performed using air. This technique is used for cutting all types of industrial steels, aluminum, copper and their alloys. Air-plasma cutting is the most economical kind, and therefore the most popular. Also cutting can be done using:

• Oxygen. This technology is used for cutting steel sheets for manufacture of parts of high quality.
• Nitrogen-oxygen mixture. This technique is also used for cutting only steel in the case, if you want to increase the speed of work.
• Argon-hydrogen mixture. This method is great for cutting edges of workpieces of copper and aluminum.
• Nitrogen. This inert gas is also mainly used for cutting aluminum and copper products. Plasma cutting of metal with its use is considered economical. Sometimes nitrogen is used when cutting sheets of corrosion resistant steel.

Table of Assembly

This subassembly of equipment such as plasma cutting machine, CNC may be a single system with the main unit or installed separately. The first optionused when working with small workpieces. The main advantage of that type of equipment are compact in size. For heavy items use freestanding tables. The fact that the weight of the blanks in their elements over time SAG. To replace the individual table is much simpler element is rigidly connected with the main unit.

Air-plasma cutting, oxygen and with the use of inert gases — a procedure which produces a lot of abrasive. Therefore, the tables of machines of this type are equipped with special dust-proof Pneumatics. In the lower part is a system of smoke and metal particles. The table itself consists of several plates arranged at regular intervals.

CNC router machine

The structure of the unit may differ in:

• Diagonal screen;
• Degree of sophistication of the interface;
• View of the used SOFTWARE.

The Most convenient are CNC, among other things, equipped with a modem. When using such electronics the operator has the possibility to contact the supplier directly if necessary change the settings of the machine or correction of any errors.

CNC can control the cutting process, but also the stability of equipment operation. In case of detection of any incompatibility with the parameters laid down, the computer blocks the Assembly that prevents the production of defective products, and often damage different kinds of units and mechanisms.

The Price of machines

How much can cost modern plasma cutting device? The price for equipment of this type depends on the brand (build quality), performance, functionality and complexity of the CNC system. Large gantry machines today are an average of 700-1000 rubles. The price of more compact machines of less power and size ranges of 300-600 thousand.

Thus, the modern machine designed for plasma cutting, we can assume the equipment is very convenient and productive. In particular, the purchase and installation of the plant such equipment is advisable, if the product is expected to produce large quantities.
