Of great importance is the fact that the quality of the cut always remains consistently high, and it does not depend on the thickness of the processed metal sheets.
Types of plasma cutting machines for metal
Plasma cutting machines are available in two versions: mobile (compact) and stationary. Each of them has its own advantages and is used in a wide variety of industries. You can get acquainted with the mobile type, which can be used when processing relatively small-sized workpieces, in the article “Plasma cutting machine “SVAROG CUT” 70 (R33)”.
When a large amount of work is to be done on cutting wide-format thick metal, it is economically feasible to use portal-type installations. This type of arrangement of movable structural elements can significantly improve the accuracy of processing. Equipping equipment with numerical control (hereinafter referred to as CNC) greatly facilitates the setup and operation of the machine and increases labor productivity.
If there is no need to constantly process large workpieces, then portal portable metal plasma cutting plants are used. The working tables of such machines, in case of the need to cut large workpieces, can be extended using modules to the required length.
The role of CNC in the operation of a portal plasma cutter
The role of the CNC in the operation of the gantry plasma cutting machine is as follows. There is a library of CNC programs to perform the most common metalworking operations. They are called "standard operations programs" (hereinafter referred to as SOPs). When preparing technological documentation for the manufacture of a specific part, they take the closest PSO in terms of configuration, modify it accordingly (to the desired shape and size) and record it on a standard media compatible with the CNC of the plasma cutting machine. Further, in the process of setting up the machine for processing a particular part, you only need to load this program.
Thanks to the CNC, all operations are carried out without delay, since plasma cutting is carried out according to a pre-set program. The operator of the machine can only control the progress of the technological process.
Advantages and features of portal CNC plasma cutters
If it is necessary to perform a large amount of work on cutting thick metal, it is economically feasible to use CNC gantry plasma cutting machines for the following reasons:
- the use of such equipment is economically feasible;
- processing thick metal on such equipment allows you to get a cut High Quality, which, in most cases, will not require further machining;
- the presence of CNC can significantly increase labor productivity and facilitate the work of the operator of the portal plasma cutter;
- Plasma method of cutting metal under CNC control and control allows to obtain very high precision in the manufacture of parts. In addition, the equipment allows you to cut any contour, up to an angle (bevel) of 45 degrees (this option is used for chamfering). In the future, after such cutting, only minor mechanical refinement (for example, chamfering) may be required;
- equipment is highly reliable. To increase the service life, a smooth start of the mechanism is provided on the CNC portal plasma cutting unit. This makes the operation of the machine durable, and the process safe;
- The high power of the torch and plasma source, combined with the right software, enables high productivity over a wide range of workpiece thicknesses and sizes.

What is a CNC plasma machine and its device
Plasma machine is a device for processing the surface of metal different ways. Machine tools differ from each other in their internal structure, the way the worksheet is placed, the main purpose, and also the way they are controlled.CNC plasma metal cutting equipment is controlled by computer program, which automatically controls all the necessary parameters: the angle of inclination of the cutter, the output voltage power, etc. The device of such machines includes:
- Plasma cutter.
- Apparatus for supplying voltage and compressed air.
- cutting system.
- A device for moving a cutter along a metal surface.
- Cutting process control system.
What are the machines for cutting metal with plasma
Plasma cutting machines are different technical specifications, performance and design features. The main difference is the following:
In general, CNC machines have a simple structure and principle of operation. The only prerequisite for operation is that the operator of the CNC machine for cutting metal with plasma has a special specialized education.
The principle of operation of CNC machines for cutting metal with plasma
CNC plasma cutting machines differ from manual stations in that all work processes in the devices are fully automated by program control. The presence of CNC has reduced the impact human factor and achieve a new cut quality.Thanks to the use of a computer that monitors the execution of operations, the functionality of the equipment has been increased and the scope of applications has expanded. The principle of operation, with the exception of process automation, remained unchanged:
- The cutter is supplied with air under pressure and the corresponding swirl.
- With the help of an electrode, the air is heated to a temperature of about 20000-30000°C.
- At the moment of heating, the air masses undergo an ionization process and as a result become a good electrical conductor.
- Heated air - plasma melts the surface of the metal and blows it out under pressure.
feature industrial equipment is that all processes are controlled by the program for the plasma cutting machine. The software allows you to take into account many factors that ensure the quality of the cut. Namely: 
Additional convenience during work is provided by the CNC coordinate table for plasma cutting. The coordinate table helps to perform the most accurate and high-tech types of material processing, which are subject to increased requirements.
Safety and operation requirements for CNC plasma machines
Plasma metal cutting machines are relatively safe equipment, to which, however, certain requirements are imposed, regulated in GOST 12.3.039-85 and others. normative documents. GOSTs and documentation stipulate certain conditions related to both service personnel as well as installation. Among the main provisions are the following:- It is mandatory to use funds personal protection for the operator. Gantry CNC plasma cutting machines generate low-frequency noise at the ultrasonic level, certain infrared and electromagnetic radiation, as well as nitric oxide products and other harmful fumes during operation. When working, the use of protective glasses, headphones or earplugs, etc. is required. A special ergonomic chair must be installed for the operator.
- Features associated with the process of operation of the equipment impose special requirements for ensuring safety in the workplace. The room used for the installation of the machine must be well ventilated and have sufficient daylight. The use of forced ventilation systems is mandatory.
- Quality Supplies– portal and portable mobile CNC machines for plasma cutting of metal must have a unit for preliminary preparation of the materials used. Using compressor unit an air dryer is additionally installed if it is not built into the structure.
- Automatic shutdown systems - CNC plasma cutting may be associated with certain emergency situations. Control systems provide automatic shutdown of the machine in case of violation of operating standards.
- There must be fire extinguishers in the room, and a fire alarm is installed. The operator is instructed on the necessary actions in case of fire.
The operator of the CNC machine for performing plasma cutting of metals must undergo mandatory training on the safe operation of the device, have permits to work with equipment of this type.
The room used for work must be checked by a fire inspector. From time to time, the device will be re-qualified for compliance with the requirements for the safe operation of the device.
