A “CNC plasma” system is a machine that carries a plasma torch, and can move that torch in a path directed by a computer. The term “CNC” refers to “Computer Numerical Control”, which means that a computer is used to direct the machines motion based on numerical codes in a program.
What is the difference between CNC and plasma cutter?
The CNC plasma cutter can cut various materials of metal, and the cutting speed is relatively fast; the CNC laser cutting machine can cut metal, leather, and plastic materials; the flame cutting machine can only cut carbon-containing metals. … However, the CNC cutting machine has a cutting range.
How does CNC Plasma work?
CNC plasma cutting machines are computer-run systems that have the ability to move a high-definition plasma torch in various directions by using the numerical coding that has been programmed into the computer. … An electric arc is then introduced to the gas, creating plasma which is able to cut through metal.
What is plasma cutting CNC?
What is CNC Plasma Cutting? Plasma cutting is a process that uses an accelerated jet of hot plasma to cut through electrically conductive materials. Common materials that might be cut with a plasma torch include steel, stainless steel, aluminum, brass, and copper.
Can you make money with a CNC plasma table?
Plasma tables are able to cut materials much differently than a CNC mill. … “Everyone loves something ‘cut in metal’. It is substantial and permanent,” he says. Sign making is a pretty basic business, and you can provide products to your customers at fairly reasonable prices while still making a profit.
Is a plasma cutter better than a torch?
Cutting precision: Plasma typically cuts quickly and with minimal slag, providing smooth cuts with a narrower kerf than what’s produced by oxy-fuel torches. … Better cutting on shaped metals: When the workpiece has angles, channels or tubes, plasma cutting can provide faster and more precise cutting performance.
Can a plasma cutter cut wood?
Plastics and wood are not electrically conductive and cannot be plasma cut. However, you can use a rotary saw, router, or other tool if you want to cut these materials in the PlasmaCAM machine. The accuracy of the machine is better than that of the plasma cutter.
How much does a CNC plasma cutter cost?
Depending on type, size, and features, a CNC plasma cutting machine could range anywhere from $15,000 to $300,000. That’s a big range, but the vast majority of CNC plasma machines sold today are well below the $100,000 mark.
What can a CNC plasma cutter cut?
A CNC plasma cutter is usually designed for cutting sheet metals, metal signs, metal arts, metal tubes & pipes, and other metal fabrication projects in small business or industrial manufacturing.
Which plasma cutter is best?

How much does a CNC plasma table cost?
Depending on its size and features, a plasma CNC cutting table can cost between 12,000 and $300,000.
How thick can a 50 amp plasma cutter cut?
Excellent Air Plasma Cutter: The Cut-50 Plasma Cutter can easily cut up to 0.55”(14 mm) metal under maximum output with ultimate portability weighing only 21.56 lbs.
Can you cut cast iron with plasma cutter?
The more energy added via the plasma cutter, the hotter the plasma arc becomes, providing more cutting capacity and efficiency. … One of plasma’s greatest advantages is its ability to cut non-ferrous metals such as aluminum, stainless steel and cast iron, materials that are becoming more common in many applications.
How hard is it to use a plasma cutter?
The idea behind a plasma cutter is to cut tough-to-manipulate metal using very high temperatures that turn gas into plasma. … Even though there are a lot of intense reactions and very high temperatures forming inside a plasma cutter, the user’s part is relatively easy.
What is needed to operate a plasma cutter?
Plasma cutting requires two basic elements — air and electricity — so the next question to ask is what type of input power is available. Several 30-amp plasma cutters, such as the Spectrum® 375 X-TREME™, operate using 120- or 240-volt power.
What is a disadvantage of plasma cutting?
Unfortunately, plasma cutting does have a few drawbacks. Most plasma cutters aren’t useful for thicker or denser metals. The fleeting nature of plasma limits their range to a depth of about one inch.
Is plasma cutting the same as welding?
Tig welding basically melts the two metals together while mig welders use a filler material, (a consumable electrode). … Plasma cutting has allowed metal workers to create professional, precise, clean cuts.
Can I weld with a plasma cutter?
With the right torch design, a nitrogen-water injection, less expensive than other gases, can work well when plasma cutting aluminum and stainless material for subsequent welding. The process involves an electrode surrounded by nitrogen, which is heated by an electric arc to form the plasma.
Is a plasma table a CNC machine?
4×8 industrial CNC plasma table kit with flame cutting torch is a commercial CNC plasma cutting table used for sheet metals and metal tubes with a rotary attachment, which is also known as CNC oxy-fuel cutting table or CNC flame cutting table with plasma torch.
How accurate is a CNC plasma cutter?
High quality CNC cutting machines deliver accuracy far tighter than the plasma arc and oxy-fuel processes. Generally, the expected accuracy for the high definition plasma cutting process is approximately +/- . 040” (material thickness dependent) and +/- . 125” for oxy-fuel cutting of heavy plate.
Is a plasma cutter a laser?
While the answer is not cut and dry, there are some general rules that separate the two processes. Laser cutting is a precise thermal cutting process, utilizing a focused beam of light. … Plasma cutting, on the other hand, uses a mixture of gases in order to form a cut.
What do you use a plasma cutting table for?
Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations.
What is a plasma table used for?
They are successfully used in the metal cutting processes in the manufacturing, agricultural, engineering and construction industries. A CNC plasma table can change the way you cut metal, serving as the perfect addition for a small shop, a metal artist or a hobbyist and it can help save time, material and money.
