About metal processing

Metal working is a technological process of changing the shape, size and properties of metal workpieces, by processing them using various methods. The main methods of metal processing include the following:
This is the most extensive group of metal processing, which consists in the removal of excess material using special tools, such as cutters, drills, cutters and others, and, as a consequence, giving the part the desired shape and dimensions. Both CNC (automated) and general-purpose (manually operated) machines are used for manufacturing products using this method. The main processes of mechanical metalworking include the following:

  • Milling or CNC milling, in which the cutting tool rotates around its axis, cutting off excess material from the workpiece fed to it
  • Turning. A type of machining of cylindrical, conical, and shaped elements in which the workpiece rotates about its axis and the cutting tool performs a translational motion, thereby removing the excess layer of material.
  • Drilling. Used for obtaining the holes of desired diameter and depth.
  • Boring. A process by which one can get high-precision holes, unattainable by simple drilling, through the use of precision equipment – boring heads.
  • Broaching and planning. Similar processes in principle, mainly used to produce splines, gears and profile grooves.
This process is also called grinding. Includes the following types:

  • Circular (cylindrical) grinding of both external and internal surfaces
  • Flat grinding – grinding planes and ends of workpieces
  • Profile grinding – grinding of curved surfaces, both CNC and manual
It is one of the most precision types of metalworking on CNC machines and consists in removing metal with a series of rapidly repeated electrical discharges that occur between the workpiece and the tool (electrode or wire). Depending on the tool, this process can be divided into the following types:

  • Wire EDM, in which electrical discharges pass through a high-precision wire made of special alloys
  • Sink EDM – a process in which a series of electrical discharges are passed through a pre-made electrode, completely repeating the shape of the element to be obtained
A process used to improve the properties of a material by means of temperature. The main types include the following:

  • Hardening
  • Hardening
  • Hardening
  • Aging
  • Normalization
In this case, acids and various chemical reactions are used. It is mainly used for engraving or polishing finished products.
This is a the process of shaping and forming desired elements by using direct force of the tool on the material to be worked.
