What Is A CNC Plasma Cutter?
CNC plasma cutters are computer numerical controlled metal cutting machines that use plasma torch to cut metals into different profiles and shapes with CNC controller, including mild steel, stainless steel, carbon steel, galvanized steel, hot rolled steel, cold rolled steel, iron, brass, copper, alloy, aluminum, bronze, and titanium. A CNC plasma kit is composed of machine frame, plasma CNC controller, plasma power supply, plasma torch, blade or sawtooth plasma table, driver, motor, plasma CNC cutting system, plasma CNC cutting software, guide rail, ball screw, optional parts and consumable parts. CNC plasma cutter is also known as plasma CNC cutter, CNC plasma table, CNC plasma cutting machine, CNC plasma cutting table, CNC plasma cutting system, CNC flame cutting machine, CNC oxy-fuel gas cutting machine, CNC flame plasma cutting machine, CNC oxy-fuel cutting machine, CNC plasma & oxy-fuel cutting machine.
How Does A CNC Plasma Cutter Work?
Plasma cutting is a machining method that uses the heat of a high-temperature plasma arc to melt at a metal workpiece, and to eliminate the molten metal by high-speed plasma momentum to create a slit. Plasma cutters send an electric arc by using gas like oxygen, nitrogen or compressed air. This turns the gas to plasma, as well as it promptly blasts through metal to cut it with broadband. A flame cutting torch works by adding a blast of oxygen to the flame which oxidizes the metal and turns it into slag. The plasma torch moves with a tool path directed by a computer. The term “CNC” means “Computer Numerical Control”, which implies that a computer is used to control the motion supported G-code in a program. Compared to handheld plasma cutters, plasma CNC cutters realize automatic machining with high efficiency, high speed, and high quality.
What Are Plasma CNC Cutters Used For?
What materials can a plasma cutter cut? Plasma CNC cutters are used for cutting sheet metals, square and round metal tubes, including iron, cold rolled steel, hot rolled steel, stainless steel, galvanized steel, carbon steel, copper, brass, alloy, bronze, aluminum, titanium. Plasma cutting machines are widely used in the industries of machine tool manufacturing, petro-chemical equipment, light-industrial machinery, pressure vessel, shipbuilding, mining machinery, electric power, bridge construction, aerospace, steel structure, etc. Plasma cutters can be applied to hobbyists, home shop, home business, small shop, small business, school education, industrial manufacturing.
How Many Types of Plasma Cutters?
The most common types of plasma cutters include handheld plasma cutter (portable plasma cutter) and CNC plasma cutter (hobby CNC and industrial CNC). The most common plasma power supplies include Huayuan plasma cutter and Hypertherm plasma cutter.
According to the working methods, plasma cutting kits can be divided into dry plasma kits, semi-dry plasma kits and underwater plasma kits.
According to the cutting quality, plasma cutting kits can be divided into ordinary plasma kits, fine plasma kits, laser-like plasma kits, and so on. According to the appearance types, plasma CNC cutters can be divided into:
Portable CNC Plasma Kits
The machine is portable, easy to setup, compact in structure, small in space and low in manufacturing cost. However, due to the limitation of the cantilever structure, the stress conditions are poor, the transverse deformation is prone to occur, the transverse cutting width is limited, and the rigidity is poor during high-speed cutting.
Gantry CNC Plasma Kits
The gantry-type supporting method is bidirectionally supported, the force is more uniform, the equipment has good rigidity, and can achieve a large lateral span, usually up to 3 to 10m. However, the equipment installation requirements are high, the structure is relatively large, and it takes up more plant area. The driving mode is divided into unilateral driving and bilateral driving. Unilateral drive and bilateral drive each 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 Table Kits
The cutting part and the machine are integrated, which is convenient to move in place, but the movement range of the cutting torch is relatively small, and the cutting width is subject to certain restrictions. How Many Types of CNC Plasma Tables? The most common types of CNC plasma table kits 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).
Advantages of Plasma Cutting?
Plasma cutting is an efficient metal cutting method for sheet metal and metal tubes, which has made it to be widely used in many different industries. You can get benefits from 10 best advantages with fast cuts, ease of use, lower cost, safe to use, multi-tasking, expanded versatility, wide range of material and thickness, eliminated plate warping, raised inside piercing speed, and diminished dross.
Compared with traditional manual & semi-automatic metal cutting method, automatic CNC metal cutting system is an integration of quality improvement and cost-efficiency. CNC metal cutting machines include computerized numerically controlled plasma, flame, water jet and laser cutting machine. It performs automatic, full-time, high-quality, high-utilization and efficient cutting according to the CNC nesting software.
In industrial production, metal thermal cutting generally includes gas cutting, plasma cutting, and laser cutting. Compared with gas cutting, plasma cutting has a wider cutting range and higher efficiency. The fine plasma cutting system is close to the quality of laser cutting in terms of the cutting surface quality of the material, but the cost is much lower than that of laser cutting. It has shown great advantages in saving materials and improving labor productivity. This has promoted the development of plasma cutting system from manual or semi-automatic to numerical control, and has become one of the main directions of the development of numerical control cutting technology.
1.It can cut thicker metals, such as stainless steel, aluminum and its alloys, copper and its alloys, cast iron and other metal materials. You can also use plasma gun to cut insulating materials and non-metallic materials with thickness of more than 150mm.
2.The cutting speed is fast, and the production efficiency is high, especially when cutting thin metals with high power, the production efficiency is improved more significantly.
3.The cutting quality is high, the slit is smooth and flat, the incision is narrow, and the heat-affected zone and deformation are smaller than other cutting methods.
4.Low cost, due to the high speed, the use of cheap gas such as nitrogen requires less raw materials and labor than other methods to cut the same material.
How Much Does A CNC Plasma Cutter Cost?
According to different requirements and configurations for plasma power supply, plasma torch, plasma CNC control system, sawtooth or blade plasma table, motor, driver, plasma CNC cutting software, plasma CNC cutting system, machine frame, guide rail, ball screw, optional parts and consumable parts, CNC plasma cutters have an affordable price range from $4,280.00 to $18,000.00 within your budget.
