The CNC plasma cutter consists of:

• power source

• plasma torch

• ground cable

• power line

• compressed air supply (option)
  

• cooling

• CNC machine

CNC plasma cutter or plasma torch is a tool that is able to cut metals through a generated arc between an electrode and the workpiece. The intensity and stability is increased by the supply of compressed air which is added through a cutting nozzle during the procedure. The result is a high-energy heated gas in the plasma cutter. So energetic that this is immediately converted into heat. Very hard materials such as steel, stainless steel, cast iron, copper and aluminum can be cut without any problems with a plasma cutter. Hardly any other device can cut so precise cuts and shapes metal. The cuts are clean and to accomplish much faster. In addition, also round shapes can be cut out

Only a few years ago a skilled engraver still manually engraved workpieces in hours of detailed work. Today this highly challenging job is often done with mechanical precision by CNC photo engraving machines.

Hobbyists and beginners increasingly use a CNC-controlled photo-engraving machine. Last but not least, to save time and a lot of hard work, but also to achieve professional results.

Photo Engraving are applicable in:

• Engraving of Medallions

• Engraving of pictures on grave stones and grave plaques

• Photo engravings or logos of any kind as on cups, machine parts, technical equipment, grave stonesNumbering of metal components (serial numbers)

• Personalizing gift items with photo engraving

• Manufacturing of individual and high quality jewelry

When purchasing a CNC engraving, it’s best to look for a technically competent manufacturer or seller. The most important rule when buying an Engraving machine or milling machines is:
The more accurate my machine is adapted to the needs of a workpiece, the more accurate the result is!
Some preliminary questions should be answered:

    Size
    What size should my engraving machine have? What are the maximum dimensions of the workpiece to be machined?
    For a gravestone engraving, I need a different size than for series identification plates. Principle of “Bigger is better” – If I buy a smaller engraving machine I am limited in terms of future projects, if I buy a bigger one, I have more flexibility in the implementation of major projects.

    Tools
    What should I consider when buying the CNC tools? The accessories are an important criterion. Here it is essential to use the right tool, suitable to the material of my workpiece and the performance of my machine. Rotating tools (Engraving) are used but also fixed Slicing machines (mostly diamond tips) for various purposes. Again, advice should come by a well-trained salesperson.

    Suction
    Do I necessarily need a suction when engraving? As it comes to increased dust production, by removed material when engraving, you should draw a suction into consideration. The dust can change the engraving depth and hence also the precision of the result. It may also (especially with abrasive materials) come to buildup on the mechanical components of the engraving machine, which may affect the function of the CNC engraving machine.

• The machine capacity

Consequently, before you send your inquiries to various manufacturers think about your project. For example, you should already have an idea of the approximate size of the materials which you will process. The traverse paths of the machine ultimately limit the size of the material that fits on the working area.

• The pump and its performance

It is also extremely important to know which materials to machine, as this also determines the choice of the required pressure performance of the pump. Softer and thinner materials such as rubber, plastic or wood require less power than harder materials such as metals, for example, cast steel or steel. A knowledgeable machine manufacturer is happy to assist you in deciding.

• Material to be machined

Furthermore, the torsional rigidity of the entire system is significant concerning the application. With water jet cutters, one can generally say that they should have high torsional stiffness. This is important since the recoil when the waterjet is switched on can sometimes cause a loss of accuracy on the material to be processed in an unstable system.

• Accuracy – Set cutting values exactly

You should configure the cutting values of the water jet cutter as ideally as possible for the material you want to process. Because the more precisely the cutting system is adapted to the requirements of the material, the more accurate and clean the cutting results will be.

With these tips, you are well prepared accordingly. You should also consider a possible prior inspection of the machine. In this case, you can also ask the manufacturer or dealer of your choice for a test cut in the material you are using. In this way, you can personally convince yourself of the construction of the machine and the working results.

You can make the water jet even more effective by adjusting the water pressure, increasing the abrasive content and adjusting the nozzle diameter. This accelerates the flow rate of the water and the abrasive particles, which results in an increased impact of the jet on the material and thus increasing the cutting force. Of course, you should note that the dosage of garnet sand should be adjusted according to the thickness of the material to be cut.
With the technique of water jet cutting, for example, various materials can be ideally and precisely processed:

    natural stone such as granite, marble, sandstone, slate, soapstone
    ceramic tiles, flagstones, porcelain stoneware, clay
    stainless steel, steel, brass, copper, tool steel
    plastics like PTFE, Plexiglass, polycarbonate
    woods like hardwood, beech, spruce, fir, multiplex
    glass and many more

You will find the versatile application possibilities with our water jet cutters in this article.

On the other hand, you can add an abrasive in the form of garnet sand or corundum to the water. This produces a corresponding water-abrasive mixture, which is therefore ideal for cutting harder and stronger materials. Most people know corundum as a material for grinding wheels. In the grinding wheel, the corundum particles are firmly bonded by means of a binder and form a solid structure as a unit of thousands of particles bonded together. In waterjet cutting, however, each particle does this job on its own.

First, one must clarify what the term “CNC” means. This abbreviation stands for the English expression “computerized numerical control“. In short, it means that an electronic procedure is used to control the respective CNC machine. This enables the machine operator to quickly and precisely implement even complex contours and shapes in a wide variety of materials.
