CNC rolling mill type

According to the direction of the spindle, CNC milling machines can be divided into two types: vertical and horizontal. Before choosing between these two types of milling for a milling project, the operator must consider the requirements of the project, such as the shape and size of the parts and the number of surfaces to be milled. For example, although vertical grinding provides more universal machining options, horizontal grinding is more suitable for heavy and long workpieces.
Another main classification of CNC milling machines is based on the number and configuration of axes. In CNC milling, the axis refers to the direction of motion of the workpiece or tool. In our network, we perform multi axis milling operations, including 3-axis, 4-axis, and 5-axis milling. We can quickly and accurately produce parts from simple shapes to complex geometric shapes based on your design. 3-axis and 5-axis CNC mills are the most popular types of CNC milling machines.

3-axis CNC rolling mill
The tool or workpiece of a 3-axis CNC milling machine has three degrees of freedom. This means they can move in three linear directions; X-axis (left and right), Y-axis (front and back), and Z-axis (up and down). In order for the cutting tool to reach certain areas of the workpiece, it is necessary to manually reposition the workpiece.
Advantages of 3-axis CNC milling
This process is easy to program and can produce parts with simple geometric shapes and high accuracy
Its production capacity is very high
The processing cost of each part is relatively low
A 3-axis CNC rolling mill is cheaper than its 5-axis counterparts
Limitations of 3-axis CNC milling
For certain processes that require more tools, constantly repositioning the workpiece can reduce accuracy
Tools cannot enter certain areas of the workpiece
It is more difficult to complete complex geometric shapes and designs using a 3-axis CNC milling machine than using a 5-axis CNC milling machine
5-axis CNC rolling mill
In addition to the three linear axes that can be achieved in its 3-axis counterpart, the 5-axis CNC mill also has two rotational axes. In most milling machine configurations, the tool can only move along three straight axes. The workpiece performs the remaining two rotational movements, allowing the cutting tool to enter another area.
5-axis CNC rolling mills can be further classified as exponential and continuous. In a five axis rotating mill, the tool must temporarily stop moving while the workpiece is rotating. However, in a continuous 5-axis rolling mill, there is no need for the tool to stop. When the tool moves, the workpiece rotates simultaneously.
Advantages of 5-axis CNC milling
It eliminates the need for manual repositioning of workpieces
It produces parts with certain very complex geometric shapes and designs them with very high precision
The surface of 5-axis CNC milling parts is very smooth. Almost no processing marks
Disadvantages of 5-axis CNC milling
The processing cost of each part in 5-axis CNC milling and continuous 5-axis CNC milling is 60% and 100% higher than that in 3-axis milling, respectively
5-axis CNC rolling mills are larger and more expensive than their 3-axis counterparts
