Best 5 Plasma Cutters for CNC

The CNC plasma cutters help in automatic cutting of metals. With this you are able to do precise, accurate cuts with neatness. In this article you will know about the best budget plasma cutters for CNC in detail and the best 5 among them are also discussed. Some of the plasma cutters are hand operated while the others are operated by CNC.

The CNC refers to the computer numerical control. The CNC table helps you to direct the torch. This will make sharp and clean cuts. The CNC helps in cutting diverse shapes. With this a level of accuracy is obtained. This cannot be managed with a handheld cutting.

The Best CNC Plasma Cutter We Recommend

This indicates that the plasma cutter in this case will be managed by the computer. And it is important for you to know that the cuts that are hand operated and computer operated are very different. The hand operated cuts will vary in the quality whereas he computer ones will be accurate.

All the plasma cutters that you know will not work with CNC. So the ones that work with CNC are listed and described below.

Herocut cut55 CNC plasma cutter

The herocut plasma cutter has a non touch pilot arc along with the non-HF arc. The pilot arc is new and this will help to reduce the interference with the electronics while you are cutting. This gives a arc that is more stable. This further adds to the life of metal. This is because it won’t touch the metal surface directly, when you begin with the arc. This protects the metal surface and enhances the life. The cutters that feature the pilot arc are cost effective.

The plasma cut has an advanced IGBT inverter technology. The other plasma cutters that feature the IGBT technology have more frequencies in the starting process, and they even use more high voltage whereas some of those use the pilot arc starting.

Also it is able to work with the CNC technology. The CNC helps t give you better precision in cuts than those which you would achieve manually.

Pros

  • It works with CNC.
  • The arc will be generated without touching the metal surface.
  • The cutting arc is stable.
  • It is easily portable.

Cons

  • Lack of instructions and provision of manual.

Some of the reviews are:

  • Cut quality is great.
  • There is ease in connections.
  • The quality is good.

Dalishi ICUT60P plasma cutter

This plasma cutter has a number of features which are required to make it suitable for industrial and commercial applications. The power used is 60 amps. The plasma cutter works with the CNC that will help to give better, accurate and more precise cuts. Also the IGBT machines are better and more stable. The MOSFET technology is not so suitable for coping with the cutting applications. This technology on the other hand will handle different types of work. These plasma cutters are used both by professionals and the industries. These are used in electrical construction, family DIY, processing etc.

  • Safety is not provided.
  • More care is too be taken

Saviron LGK-80S plasma cutter

This plasma cutter uses a current of 100 amps, and it gives more efficiency in the cutting operation. The arc does not touch the metal directly. The slag produced will be less.

The pilot starting arc will help to produce a constant arc without touching the metal surface. This will help you to reduce costs and the interference, will help to produce a stable arc and also extend the life of the plasma cutter.

This will cut a thick metal plate easily and that too in less time. The maximum cutting thickness that you get is 30mm. this will cut stainless steel, carbon steel and aluminium too.

The problems that you face while using this are related to power. This will help you to give protection against voltage, current and will make it safe for you to use.

Pros

  • The plasma cutter works with CNC.
  • Slag produced is minimal.
  • The life is extended.
  • The cutting arc is stable.
  • The arc does not touch the metal surface in the beginning.

Cons

  • Plugs are not included.

Some of the reviews are:

  • The cutting arc is stable.
  • It does not touch the metal surface directly.
  • Quality is good.

Razorweld PJRWPC45LT plasma cutter

The razorweld gives great performance and the cutting capacity is also good. The grip torch is also great and the plasma cutter will help in god seamless operations.

The plasma cutter is highly efficient and you can easily fit it in your workshop. The small size of the plasma cutter helps you to move it around easily. This plasma cutter has a euro connection feature that enhances the portability and it also helps you to interchange it when it is required.

Now let us see the CNC plasma cutters in detail.

CNC plasma cutters

The plasma cutters are of two types that is they are handheld and CNC operated.

The handheld torches can easily cut the metal pieces and the sheets. The plasma cutter is a great gouging tool. If you want to cut small shapes then you can use the hand torch. It is not possible that you achieve the accuracy or the edge for most of the fabrications therefore we require the plasma cutters.

The CNC plasma cutter is the one that operates the torch in the way computer leads it to. The computer makes use of numerical codes to direct the machine.

Handheld and the mechanized plasma cutters

The CNC cutters have different types of plasma system as compared to the handheld ones. This type of system is being designed for mechanised cutting. The mechanised plasma system provides you with the feature of straight barrelled torch. This feature is being controlled by the CNC. The CNC machines are able to support the torch for the handheld cutting. The machines which are being designed for the severe manufacturing also have a mechanised torch.

Parts

The CNC plasma cutter that we are discussing has two main things. This can be a complete controller for the machine tools, that has an interface panel and it also has control consol. However, it could be like the windows software that runs a laptop and communicates with a machine.

Some of the machines like the HVAC machines or the precision machines can also work with a computer. The motion and the working of the torch are controlled by CNC. The M-codes and the G-codes are present in a text file that mainly represents the instructions to control the torch. The programs are written by the processor and there is a CAD file. The programs will be translated into the G-codes and the M-codes that can be easily read by the CNC.

There is a drive system for the plasma cutter. The drive system involves the amplifiers, encoders, cables etc. There should be two motors that is one for the X axis and one for the Y axis. Each motor showcases its own drive amplifier; with this you can convert the low power signals to high power signals. The motor then gets the power from the amplifier and then it is transported to the CNC. After getting the programs, the CNC gives output to the drive system. As a result the drive system makes the torch move and that too in the desired speed.

The feedback is then read by the CNC and then the required corrections are made to the drive. By this the torch will remain on the required path. These can measure the information and change it after every few seconds. Due to this the machine has good motion and the cuts are produced accurately.

The CNC plasma systems have the input and output systems. There is an electrical system that controls the input and output systems. This system helps to turn the plasma on and off at the appropriate time. The CNC makes use of input sources to know about the plasma arc and whether it has started or not. These are some of the necessary inputs and outputs that are necessary. There are many more important things to know about it. There are a number of features and the subsystems of the plasma cutters. This involves the arc voltage control systems, plasma level and integrated plasma systems. Also all these features are the basic features of the CNC plasma cutters ad these are common to all the plasma cutters based on CNC.

Conclusion

Choosing a plasma cutter for your work is not an easy task for you, especially if you want the one that is being operated by the computer. With the information that is provided to you about the plasma cutters, it is sufficient to know about the CNCC and pick one for yourself.

It is really difficult to choose the best one out from the best five listed in the above article. But the Saviron LGK-80S is one of the best pick. This machine operates at 100 amps and the cutting is operated smoothly. The pilot arc does not touch the surface of the metal I the starting and it cuts the painted surface nicely.

The second best is the Herocut cut55. This is a 50 amp plasma cutter which also has the non touch pilot arc along with dual voltage.
