The Complete 5 Axis CNC Milling Machine Guide

Posted on Sep 22, 2020

5 Axis CNC Milling Machine

Synchronous 5-axis technology makes it possible to create highly complex shapes, suitable for aerospace components and prismatic parts of almost every material. The rigid built-in table of a 5-axis CNC machine tool can generally tilt up to 150° on the A-axis and rotate up to 360° on the C axis. The key source of several factories and workshops are 5-axis CNC machine tools.

These devices have been once reserved for complex technical projects. The importance of using the five-axis machinery in any project is now understood by large and small producers. Many could reduce delivery time, increase productivity, and thereby increase profitability. A 5-axis CNC frying machine has one of the most obvious advantages of reducing the time needed to complete the job.

There can be several different settings and longer than five hours for a typical 3-axis machine tool to complete, and its 5-axis machining tool may complete parts in multiple operations in less than two hours from start to finish. Let us tell you everything that you need to know about 5 axis CNC milling machines.

What Is a 5 axis CNC Milling Machine?

The configuration of some jobs is very complicated. To process such operations, a 5-axis machine tool is required. A 5-axis machine tool has 3 conventional VMC machine axes and 2 rotating axes, which can be used for most complex workpiece processing, so people also call it a 5-axis machining center. 5-axis machining includes all axes of 4-axis machining, as well as an additional rotation axis. The best currently available CNC milling machine, which can manufacture precise and complex artificial-bone components, aerospace products, titanium sheets, oil and gas components, automotive molds, medical products, building equipment, and military products, is a 5-axis milling machine.

The fifth axis in a 5-axis milling machine revolves around the B axis, and the B axis rotates around the Y-axis in the X-Y-Z plane. This multi-dimensional rotation and tool movement enable the B axis to have unparalleled precision, smoothness, and speed in the production of workpieces. Five-axis machining produces very complex parts, which is why it is so important in advanced applications such as aerospace applications.

How to Choose the Right 5 Axis CNC Machine​

First, consider your part. How old are they? How much do they weigh? How accurately do they have to be? For instance, a tiltable benchtop mill would be the best option if the parts are small and medium-sized with today's technology. If the component is larger and heavier, it may probably be the only choice – perhaps a joint on a portal or a horizontal machining center. Alone with this, you can limit the choices and compare the characteristics of different machine models in the necessary range.


3+2 and 5 Axis Milling Machine Applications

5-axis machining may provide a more complex final product as a whole, but the 3 + 2 axis has some nice applications. 3 + 2 axis machining is very suitable for parts that do not require extreme contour control, such as fixtures, fixtures, housings, and other such parts. If you need to make a design with great functionality, then true 5-axis machining may be the best for you. Five-axis mechanisms are particularly useful for vehicles, aerospace, or medical components due to improved efficiency and finishing. In short, tighter tolerances and complicated geometry are more fittings for 5-axis machining. This is not the end of the debate, however. As already stated, 3 + 2 axis machining has obvious advantages that make it ideal.

It is cheaper on the one side than machining with a five-axis. Raw machining and other violent high-speed machining techniques are typical applications for 3 + 2 operations. The shorter tool length can also be used for undercutting on cavities and steep walls. This feature is ideal for mold making and other workpiece applications involving curved or angled tubular shapes. Compared with traditional 3-axis machining, 3+2 machining uses a shorter rigid cutting tool that can be angled to the work surface to achieve faster feed and speed. Although 5-axis machine tools have come a long way in terms of price in the past few years, it also reflects many of the advantages of 5-axis machine tools, but the price is not higher.


Trunnion Models

The rotation axis of the trunnion type 5-axis CNC milling machine is represented by the movement of the worktable, while the rotary-rotary machine tool is represented by the rotating spindle. Both have their own benefits. For example, trunnion machines can provide a greater workload because there is no need to compensate for the space occupied by the rotating spindle. On the other hand, turntable machines can support heavier parts because the workbench is always level.


Swivel Head Models

The rotary head type 5-axis CNC milling machine has the following advantages: Since the worktable is fixed, the rotary head/rotary table machine tool can be used for heavier parts. They are also very versatile because you can add a large bench vise and use the extra space to complete the sixth side of the part or perform 3-axis machining. In addition, when the rotating head tilts the tool, you don't have to worry about the tool interfering with the spindle head of the machine tool. Finally, with the rotating head/turntable configuration, you can run the machine horizontally and get better chip control.


What to Expect from the Costs?

What is the cost of a 5-axis CNC milling machine compared to a 4-axis CNC milling machine? This is a concern for many people. If you choose a 3 + 2 5-axis machining center, the biggest cost difference is the 5-axis CNC turntable. The cost of 5-axis CNC turntables of different sizes varies greatly, and the price of different 5-axis CNC controllers varies greatly. These will affect the cost of the 3 + 2 5-axis CNC milling machine.

It should be pointed out that the five-axis CNC milling machine is a very expensive investment and requires very professional CNC technology. If you are a 5-axis machining enthusiast, you can choose a desktop mini 5-axis CNC milling machine. You can also consider buying a small 5-axis CNC milling machine.
