Regardless of a particular OEM machine tool builder, there are several common machine configurations for 5-axis CNC machines that are available - and each one has its own set of strengths that make it stand out among the choices. The most common types are: Table-Table, Head-Table, and Head-Head configurations.
But first things first…when talking about 5-axis machining center configurations, I always begin by clarifying the correct definition of each of the rotary axes. Often times, when discussing a particular machine type, people will refer to the rotary axes incorrectly…so I like to use this as an opportunity to teach! If you think about the linear axes of the machine in alphabetical order (XYZ), you can also think about the rotary axes in the same manner (ABC). The A-axis always rotates around the X-axis, the B-axis always rotates around the Y-axis, and the C-axis always rotates around the Z-axis. This is true, regardless of the machine configuration or machine tool builder.
One of the most common configurations – or at least the one most people identify with the most when they hear the term “5-axis CNC machine” – is the trunnion table machine. The trunnion configuration can also be referred to as a Table-Table configuration…because both rotary axes are contained in the trunnion table itself, and the head is always stationary.
Machined components for industrial applications are highly complex and often engineered to 5-axis machining and require precision engineering for production. In short-run production cycles, the development time of components significantly reduces. Components made are typically in materials such as; aluminum, stainless, and titanium, which companies like Rapid Axis readily utilize.
I've found that having a good supplier such as Rapid Axis can configure their machining operations to have low waste and great finish.
