CNC milling – precision machining of metals and other materials

There are several popular and widespread methods for machining various materials, including metals, wood and plastics. One of the more commonly used is certainly CNC milling, and GOMET also has such services for its customers.

This method of machining uses modern CNC (Computerized Numerical Control) machines, digitally controlled, with a precision of operation incomparably greater compared to traditional manual machining.

What is CNC milling and where is it used?

Before you decide to use our services, you should first learn what CNC milling actually is, as experts define the term. It is a complex, precise machining process using a computer-controlled device, a CNC milling machine.

It removes successive layers of machined material with the help of various milling tools, called cutters, until a part with the exact shape and dimensions specified in the design is obtained.

Digital control of milling movement ensures not only high accuracy, but also repeatability, making it possible to produce large quantities of the same parts in a short period of time. As a result, CNC milling is widely used in many economically important industries, including such as:

construction;

energy;

medical;

automotive;

machinery industry;

arms sector.

How does the CNC milling process of various materials work?

In order to better understand what CNC milling is all about, it is useful to know exactly how the entire process works, from placing a raw piece of, for example, metal in the machine to obtaining the finished part. The entire process consists of several consecutive steps:

Stage 1 – component design (CAD)

The design of the expected component is developed using CAD software, a 3D model. If it is necessary to replicate an already existing object, its design is created using laser scanning.

The design includes such important data as the shape of the object, its dimensions and the allowable tolerance of the part.

Stage 2 – device programming (CAM)

The next step is to import the finished model into the CAM software that controls the milling machine. The software converts the entered data into instructions responsible for precise machine movements.

The most important operating parameters can be determined in this way, including the depth and speed of cut and the path of movement of the cutting tool.

Step 3 – preparing the milling machine for operation

What do our skilled operators with extensive knowledge and professional experience do?

They do a full setup of the machine, covering such issues as proper, secure attachment of the semi-finished product.

They also need to choose the right cutting tools, different sized cutters, and mount them in the spindle. It is also necessary to precisely align all axes (X, Y, Z) to ensure the accuracy and stability of the milling machine.

Stage 4 – CNC machining

Once the semi-finished product is fixed and all parameters are carefully checked, machining can begin. Rotating cutters gradually remove successive layers of excess material, according to the program entered into the memory of the CNC machine.

Precise and digital control over the movements of the cutting tools makes it possible to obtain even the most intricately shaped parts. The entire process is supervised by the operator for safety, but the milling itself is automatic.

Which types of CNC milling machines are most commonly used?

Several types of milling machines suitable for processing metal and other materials are used, and the most common models are:

3-axis;

4-axis;

5-axis;

Horizontal (most versatile and suitable for large parts);

Vertical (used for milling small parts).
