CNC metalworking - what is it and what are the advantages of this process?

CNC metalworking (Computer Numerical Control) is an advanced manufacturing process in which computers are used to control metalworking machines. CNC enables precise cutting, milling, drilling and turning of metals according to programmed instructions, which are entered into the machine in the form of a numerical code.

It includes a wide range of technologies that allow for the implementation of various operations depending on the needs. Here are some of the most commonly used technologies in CNC machining:

Technologies used in CNC metalworking:

01

CNC milling

  • It is used to remove material from the surface of the metal using a rotating cutting tool.
  • It allows for the creation of complex shapes, pockets and holes in the metal.
  • It uses various types of milling cutters, including face milling cutters, cylindrical milling cutters, conical milling cutters.
02

CNC turning

  • A process in which the material is rotated around an axis and the cutting tool moves along the surface of the material, removing it.
  • Ideal for creating cylindrical and conical parts such as shafts, bushings, and threads.
03

CNC Drilling

  • Drilling holes in a material using a rotating cutting tool.
  • Can include operations such as drilling, reaming, boring, and tapping.
04

CNC Grinding

  • Used to achieve very precise surface finishes and accurate dimensions.
  • Uses grinding wheels to remove material from the metal surface.
  • Uses a high-energy laser beam to precisely cut and shape metals.
  • Ideal for cutting thin sheets and precision parts.

Advantages and applications of these technologies:

01

Precision and repeatability

All of the above technologies enable high precision and repeatability, which is crucial for mass production.

02

Complex shapes

Allows the creation of very complex and precise shapes that would be difficult to achieve using other methods.

03

Material versatility

CNC technologies can be used to process a wide range of metals, including steel, aluminum, copper, titanium, and special alloys.

04

Waste reduction

Precision CNC machining minimizes waste, which is beneficial from both an economic and ecological point of view.

05

Increased efficiency

Automation of the machining process allows for reduced production time and increased efficiency, which is especially important in the mass industry.

Application examples:

  • Aircraft: Production of precision jet engine components, aircraft structural components.
  • Automotive: Creation of engine parts, exhaust systems, suspension components.
  • Medical: Production of surgical instruments, implants, precision medical equipment components.
  • Electronics: Production of housings, connectors, radiators, and other electronic components.
  • Machinery industry: Production of parts such as shafts, gears, housings, bearings, bushings, and other mechanical components.

Here are the most commonly processed materials in CNC metalworking processes:

  • Steel
  • Aluminum
  • Copper and its alloys
  • Titanium

CNC metalworking, thanks to the use of various technologies, is a key element of modern industrial production, enabling the achievement of high quality, precision and efficiency.
