What Is A CNC Plasma Cutter
cnc plasma cutter is a kind of CNC metal cutting machine which controls the movement of precision machinery through computer and servo system. It takes Hypertherm plasma cutter which generates high-temperature plasma arc to melt (and evaporate) the metal at the workpiece incision, and uses the momentum of high-speed plasma to eliminate the molten metal to form the incision, so as to achieve fast and accurate cutting of any graphics.
Plasma cutter cnc machine integrates the advantages of high-speed plasma and high-speed plasma Numerical control technology, computer software, hardware technology, plasma cutting technology, precision machinery technology in one of the high-tech.
Because of its high speed, high precision and high automation, NC plasma cutting replaces the complicated and backward manual and mechanical operation. Because of its relatively small investment, simple maintenance and low operation cost. It is widely used in all kinds of metal processing industry.
How Does A Plasma Cutter Work?
There are four states of matter known to mankind, namely solid state, liquid state, gas state, and plasma state. When the gas reaches an extremely high temperature, it enters a plasma state, the energy begins to completely separate the molecules, and the atoms begin to split. The usual atoms are composed of nuclei, neutrons and neutrons, and electrons surrounding the nucleus. In the plasma state, electrons are split from atoms.
Once the thermal energy frees the electron from the atom, the electron begins to move at high speed. The electron is negatively charged, and the remaining nucleus is positively charged. These positively charged nuclei are called ions.
When the gas is ionized, the high-speed electrons collide with other electrons or ions, which will release a huge amount of energy. It is these energies that make the plasma state have special properties. When the clustered plasma is used for cutting, the metal is locally melted (partially vaporized) and the molten metal is blown away with a high-speed airflow at the same time, forming a narrow slit.
Not only the cutting speed is fast, but the slit is narrow, and the slit is narrow. It is flat, with little thermal influence, and little deformation of the workpiece. It solves the problem that many materials cannot be cut by flame.
Plasma cutter machine can be used for cutting works of a variety of metal materials, such as carbon steel, stainless steel, alloy steel, copper, aluminum, galvanized sheet and other non-ferrous metals
CNC plasma machine is widely applied for various industries, including: Automobile manufacturing, Ship-building, Machinery manufacturing, Pressure vessels manufacturing, Steel structure manufacturing, Metal processing, Ventilation and refrigeration manufacturing, Elevator manufacturing, Advertising, Arts and Crafts, etc.
Cnc plasma cutter machines can be divided into different types in terms of machine structure, including:
The machine has portable and compact structure, it has much advantages in small working space, easy operation and low cost. Also, both plasma cutting and oxy fuel cutting can be available on the same machine, which enable it a wide applicaiton at pretty low cost. But stress condition of portable plasma cutter is poor and thus the transverse deformation is prone to occur, besides, the rigidity of the whole structure is low during high-speed cutting, thus this portable cnc plasma cutter is mainly for small home use or metal fabricators.
The machine is another kind of cnc plasma cutter, it integrates machine bed and gantry beam on the same machine, and the plasma torch is installed onto the gantry beam, When working, the workpiece is placed onto the tabletop and torch moves under the control of controller to carry out cutting. The most common types of CNC plasma table include 4×4 plasma tables, 4×8 plasma tables, 5×10 plasma tables and 6×12 plasma tables in feet, some user may call the CNC plasma cutting table kits as 48″ x 48″ types, 48″ x 96″ types, 60″ x 120″ types in inches, some user may call the table kits as 1212 types, 1325 types, 1530 types, 2040 types in millimeter (mm).
3).Gantry CNC Plasma Kits
The gantry-type supporting method is bidirectionally supported, the equipment has good rigidity and can achieve a large lateral span, usually 3 to 10m. However, the installation requirements are high, and it takes up more plant area. The driving mode is divided into unilateral driving and bilateral driving, which have their own characteristics and applications. The unilateral drive avoids the high-precision synchronous control and complicated structure of the bilateral drive. However, due to the offset of the center of mass and the driving force does not pass through the center of mass, asymmetric inertial force will be generated during operation, which is prone to vibration, deformation and tilt.
Therefore, it can only be used in a small span. The double-sided drive structure is relatively complicated and requires high-precision synchronous control on both sides, which can be used for a larger span and more stable movement.
cnc plasma tube cutter is specially used for cutting works of different profiles, including round pipes, square/rectangular tubes, including channel steel, angle steel, U steel, beam profile, etc. This machine can carry out 2D and 3D bevel cutting on on main & brand pipes
The cnc plasma pipe cutter is equipped with advanced control system & nesting software which makes the machine an ideal solution for plasma cutting tube in industrial fabrication, especially steel structure, ship-building, machinery manufacture, etc.
Price & Cost
The cnc plasma cutting machine is composed by different modulars, such as structure, driving system, transmission system, cutting system, nesting software & control system, etc. So, the price differs much depending on actual requirements and configurations. Generally, the price of CNC plasma cutters range from $4,000 to $20,000. Besides, some extra charges & fees will have to be taken into consideration for overseas customer, including shipping costs, tax, customs clearance, etc. If you want to buy cheap cnc plasma cutter, please feel free to contact us for price detail.
