In the 1940s, when motors were employed to manage the positioning of pre-existing tools for the first time, the earliest CNC machine was introduced. Over years, with the advancement of technology, we witnessed the enhancement of mechanisms with the help of analog computers. Finally, when digital computers were designed, we hit the jackpot, as it led to the introduction of CNC machining. Today, you will see the CNC machine for sale (จำหน่าย เครื่อง cnc, which is the term in Thai) in nearly all the machinery markets. In this article, let us look into the different types of them.

CNC Mills

These have the potential to run on programs that include prompts that are based on letters and numbers. They are used to navigate pieces across manifold distances. The programming that one employs for mill machines is either based on some singular language that is developed by a team of manufacturers, or by a G-code. A basic mill has three axes:

  • The X-axis
  • The Y-axis
  • The Z-axis


In lathe machines, indexable tools are used to cut pieces in a circular motion. CNC technology ensures that the employed cuts by lathes are always done with high velocity and precision. Manufacturers use CNC lathes to produce designs that are so complex that one cannot manually run them in different forms of the machine. You can notice the similarities in the control functions of lathes and mills run by CNC. Just like the previous one, one can use a singular code of proprietary or G-code to direct lathes. But usually, the CNC lathes have only the X and the Z axes.

Plasma Cutters

The material of a plasma cutter is cut with the assistance of a plasma torch. They apply the procedure to materials of metal. However, one can also employ the method on many other surfaces. To make sure that the required heat and speed is being produced, to cut the metal, we generate plasma through a collection of electrical arcs and air gas that is compressed.

Another available CNC machine for sale is the EDM or Electric Discharge Machine. These are also called spark machining or die sinking. It is a method of molding pieces of work with the aid of electric sparks, into specific shapes. Since the discharge of current with EDMs take between two electrodes, it removes specific areas of the piece of work. There are two subtypes of EDMs that consist of sinker EDMs and wire EDMs.
