What is 5-Axis Machining? Working Principles, Types, Benefits

07 Feb.,2024

 

There are a couple of operations where 5-axis CNC machines can save much of your time and enhance your current procedure. These machines come in several types to meet the requirements of the ever-growing manufacturing industry. A unique difference in 5-Axis CNC machines is the arrangement of the rotary axes. 

Head/Head

In this type of CNC machine, the head houses its rotary axes. In this part, you do not need to worry about tool interference of the machine spindle head since the 5-axis apex is on a particular platform. Another reason not to worry about interference is that this 5-axis apex moves through a fixed table that ensures the workpiece remains in place.

This type of 5-axis machine design allows the apex to move around a particular piece during machining. Therefore, Head/Head CNC machines are ideal for producing large parts. However, along the rotary axes, this design has limited movement.

Table/Head

In this setup, there are also two rotary axes, one rotary axis is on the head, and the other is on the rotary table. Located in the head is the revolving axis, and due to the position of this axis, it has a restricted range. On the other hand, there is no limit on the scope of the rotary shaft placed on the table.

One advantage this setup has over the Head/Head is the lack of worry about reaching a specific limit because the parts are consistently revolving. Conversely, since the part or workpiece rests on the rotary axis, the CNC machine’s design limits the number of items it can produce.

Table/Table

This setup has both rotary axes on the table. There is a serious limitation to the scope of the revolving axis here, but there is no limit to the range of the rotary axis. This makes this type of machine ideal for machining undercuts. Also, compared to other machine arrangements, Table/Table has a minimal work envelope.

Additionally, it is slower than other machines since it does not come fitted with definite motors that make the other machines work fast. It is also less suitable for machining large or heavy components since they cannot carry much weight.
