Pluses and minuses of CNC metalworking
Pluses and minuses of CNC metalworking

Metalworking on CNC machines is one of the most modern methods of processing alloys. CNC machines allow specialists to produce a larger number of parts than manually at the same time. In addition, the accuracy of this method of processing metals and alloys is 1:1000, which practically eliminates the human factor.

What are the advantages of metalworking on CNC machines?

The advantages of metal processing on CNC machines include:

  • High processing accuracy is guaranteed. We manufacture any number of parts in a short period of time, the accuracy of which is 1 to 1000.
  • Exclusion of the influence of the human factor. The operator of CNC machines does not affect the quality of the production of parts, but only ensures the loading and unloading of parts from the machine, and manages its operation.
  • Performing several operations on one machine. To save time and speed up the execution of the order, it is possible to perform several operations on the same machine. The operator does not need to load and unload the workpieces each time for a new processing step.

Processing on milling machines: a multifunctional method of metal processing - this is exactly what we will talk about next. Our specialists have more than 10 years of experience in milling work, so they are happy to share their insights with the readers of our blog. Let's start with the basics!

Types of milling works

Milling works on metal are classified by:

  • by the fixing method of the processed workpiece;
  • direction of rotation of the cutting element.

Milling according to the method of fixing the processed workpiece on the machine is divided into vertical, horizontal, and corner. According to the rotation of the milling cutter (cutting element), the milling of metal is opposite and parallel.

Counter milling involves the movement of the cutting edge towards the workpiece (on the tooth of the cutter). This is the fastest processing method. The accompanying milling process consists of the movement of the cutter from top to bottom (under the teeth of the cutter). This type of metalworking guarantees a clean cut.

Both of these methods can be combined, which will ensure a much smaller number of defective blanks. For example, large workpieces should be processed first by the opposite method, and later apply the parallel method.

The type of metal surface being processed also affects the method of metal milling. Different types of milling cutters are used for surfaces that differ in the type of fastening, construction, tooth shape, and other characteristics:

  • terminal, used in the processing of large parts;
  • end ones, which are used when necessary to drill a "well" or a window in the part, to make a groove on it;
  • shaped - suitable for milling metal profiles;
  • peripheral, the feature of which is a metal chip in the form of a comma sign that remains after milling.
