The selection of the right CNC milling machine has a direct influence on your production rate as well as part quality. As there are different types and options it’s crucial to understand the difference between 3-axis and 12-axis equipment. Così, modern manufacturing processes require highly accurate skills matching the type of projects. CNC milling machines are classified according to the number of axes, 3 assi, 4 assi, 5 assi, fino a 12 assi. A 3-axis machine provides only basic functions on three different planes; suitable for simple operations. Whereas, the 12-axis machine offers multidimensional working capacity for more elaborate parts and cutting with less setup time.
This article will help you to understand the differences between 3-axis to 12-axis CNC milling machines. Inoltre, we will elaborate on their features, vantaggi, and considerations for choosing the right manufacturing machine.
3-Lavorazione CNC ad asse
3-axis machining refers to a milling process where the cutting tool moves along three perpendicular axes: X, Y, e Z. This configuration makes it possible to have accurate control in material forming and cutting.
Axes Movement:
- X-Axis: Vertical movement up and down: Horizontal movement from left to right.
- Y-Axis: The lateral movement of the body from side to side in an anterior-posterior direction.
- Z-Axis: Lateral movement sideways.
Applicazioni:
Most suitable for flat surfaces, contorni, and simple shapes are easy to machine.
Appearing in applications like aerospace, settore automobilistico, and general manufacturing of components like brackets, bases, e alloggi.
Utensileria:
Features different cutting tools such as end mills and drills that can be replaced on some CNC systems by a tool changer.
Software:
Controlled through CAD/CAM software that enables programming and process simulation.
Limitazioni:
Can only make relatively simple shapes; need to switch cutter heads for different faces; difficult to reach some areas; often cannot achieve a high surface finish on fine contours; not good for highly machinable materials.
4-Lavorazione CNC ad asse
4-axis machining is similar to 3-axis machining with the added rotation around the fourth or A-axis. This permits further motion and machining procedures, thereby improving the capacity to manufacture parts with detailed measurements.
Axes Movement:
- X-Axis: Left to right movement of the figure(progetto)
- Y-Axis: Backward and forward movement in the lateral plane.
- Z-Axis: The sort of movement to which an object moves up and down in a perpendicular direction is called vertical movement.
- A-Axis: To achieve A-axis motion, a rotational movement around the x-axis has been incorporated to allow angular cuts.
Applicazioni:
- Optimal for turning operations, complex shapes and details need to be turned during the turning operation.
- Applied extensively in manufacturing sectors such as medical, aerospaziale, automobile, and the manufacture of devices such as shafts, ingranaggi, and brackets.
Utensileria:
Uses a wide range of cutting tools as used in 3-axis machines but with the advantage of being able to employ angled tools due to the rotary axis.
Software:
Enables the use of sophisticated CAD CAM software for use in programming that in turn makes it possible to create farther and more intricate tool paths to be simulated.
Limitazioni:
Additional movements, which means more programming and setup than 3-axis, require specialized tools, longer cycle time, costlier machinery, and multi-axis machines.
5-Lavorazione degli assi
4-axis machining resembles 3-axis machining with the added rotation around the fourth or A-axis. This permits further motion in the machining procedures, thereby improving the capacity to fabricate detailed feature components.
Axes Movement:
- X-Axis: Left to right tool movement
- Y-Axis: Backward and forward movement in the lateral plane.
- Z-Axis: The sort of movement in which an object moves up and down in a perpendicular direction is called vertical movement.
- A-Axis: To achieve this motion, a rotational movement around the x-axis has been incorporated to allow angular cuts.
Applicazioni:
Applied extensively in manufacturing sectors such as aerospace, automobile, and the manufacture of medical devices for parts such as shafts, ingranaggi, and brackets.
Utensileria:
Uses a wide range of cutting tools as used in 3-axis machines but with the advantage of being able to use the tools at an angle due to the rotary axis.
Software:
5-axis CNC machining uses sophisticated CADCAM software for use in programming that in turn makes it possible to create farther and more intricate tool paths that can be simulated.
Limitazioni:
Additional movements, which means more programming and setup than 3-axis, require specialized tools, longer cycle time, costlier machinery and maintenance, and still cannot produce some highly complex shapes compared to multi-axis machines.
7-Lavorazione degli assi
7-axis machining takes the concept of CNC milling a step further by adding an extra axis of rotation and more axes of linear motion.
Axes Movement:
- X, Y, Z Axes: Ordinary lateral and vertical motions.
- UN, B, C Axes: Around the X, Y, and Z axis rotation movements.
- D-Axis: Has an adjustment for tilt or angle, which makes it even more versatile than the previous model.
Applicazioni:
- Special for complex parts with complex cutting-edge surfaces and shapes, including aircraft and molds.
- Suited for multicomponent structures that require high precision and reinforcing features.
Utensileria:
The ability to use a variety of specialized cutting tools for operations including increasing the possibility of machining.
Software:

Limitazioni: High cost of machinery; high programming skills needed; more time for setup; higher maintenance due to complexity.
9-Lavorazione degli assi
9-axis machining is the step up from 5 and 6-axis machining, as it adds even more movement capabilities to the mix, and allows it to perform very complex machining operations that cannot be done with fewer axes.
Axes Movement:
- X, Y, Z Axes: Standard linear movements.
- UN, B, C Axes: Vibrational movements along each of the three linear axes of translation.
- D and E Axes: Other rotary motion axes and tilt axes that afford higher angular adjustment.
- F-Axis: This may include additional specific motions based on machine construction that allow specific machining operations.
Applicazioni:
Ideally used for aerospace, medical implant molds, and other parts that need high accuracy and tight tolerance shapes.
Utensileria:
Able to use several complex instruments, such as multi-purpose instruments which can change functions without the need for adjustment.
Software:
Sophisticated programming is required along with a specific CAD/CAM system for high-accuracy 9-axis motion control.
Limitazioni:
Overall higher costs and is more complicated; operators must be well trained; have slower production time; and may be constrained in terms of material removal rates due to complicated design.
12-Lavorazione degli assi
12-axis machining is the highest level of CNC innovation. Generalmente, it is used where a high degree of flexibility in parts production is required. This configuration is mostly preferred in applications that are sensitive to high demands, especially in terms of geometry.
