What is a CNC milling machine?
The basis of the cnc milling machine is that the piece is fixed inside and the chipping operation is performed by rotating the tool. This rotation of the tool is done by computer software, and for this reason, this device is very accurate. This machine is also considered as one of the most accurate tools for shaping different parts.
CNC mill applications
Many industries require high precision to make their parts; such as aerospace, petrochemical, medical and similar industries. Therefore, this device has been used in a wide range of industries and is not limited to a specific industry. For example, in the medical industry, devices and parts such as artificial bones and various implants are shaped with such a device. Also, the automobile industry needs to produce complex and sensitive parts, and this machine can handle the production of such parts well. In aerospace, this machine is also used in milling.
CNC Milling Types
Types of milling machines based on the number of axes
This machine is divided into 3-axis, 4-axis and 5-axis categories based on the number of axes, the type of movement and the freedom of movement, as follows We will give a detailed introduction of each one.
3-axis CNC milling machine: In such machines, the cutting tools move along 3 axes around the part fixed in the machine. With such a device, you can perform all kinds of milling operations and forming grooves and holes.
4-axis CNC milling machine: This machine has an additional axis compared to the previous machine. In fact, this model of CNC milling machine can rotate around the X axis. 5-axis CNC milling machine: This type of CNC machine is for sensitive and complex parts of important industries. With two additional X and Y axes in this device, the cutting tool has more freedom of movement for chipping.
Types of CNC milling machines based on the type of milling
As mentioned, the CNC milling machine is divided into two vertical and horizontal models based on the type of milling machine, which we will examine each one in detail below.
Vertical: This machine with Paying attention to its name, it places the tool in a vertical position on the workpiece and the work table. For this reason and despite the fact that the cutting tool is positioned vertically in relation to the piece, it is possible to make vertical cuts, form holes, grooves and holes with this machine. One of the advantages of this device is to have a better view of the piece.
Horizontal: In this CNC milling machine, the cutting tool is placed completely parallel to the table. So, vertical type capabilities cannot be expected in this type. The main use of this type of milling machine is to make cuts on the surface of the part or to form different grooves. The grooves and surface cuts in this machine are accurate and of good quality.
The benefits of the CNC milling machine
Despite the higher cost of this machine compared to other similar machines, the benefits that this machine provides to different industries and companies can be good reasons to use it. The speed of this machine for preparing parts is not comparable to other similar tools. Also, its high accuracy makes the possibility of damage to the part to its lowest level. By using this device, many materials can be shaped and produced with any different materials.
