What is 5-axis CNC machining?
5-axis CNC machining refers to the process of controlling cutting tools along five different axes simultaneously. This method allows the creation of intricate parts. Designers love it! With greater angles and approach options, complex geometries are shaped with ease. It elevates precision, enabling the machining of highly complicated components. A must for advanced manufacturing.
What is the “5 spindle” in a 5-axis CNC machine?
To help understand the axes in a five-axis CNC milling machine, let’s explain what an axis count entails in CNC machining. A machining axis count is the number of directions in which the cutting tool (or raw material) can move to create the desired product. For instance, conventional CNC machines have a three-axis count. Consequently, their cutting tools can only move across the X, Y, and Z axes. Five-axis machining centers increase the functionalities of the linear axes by tilting (and rotating) the worktable. There are two additional rotational axes called the A-axis and the C-axis. The A-axis is also referred to as the tilting table axis, while the B-axis is the table rotation axis. Including these axes allows the machining of more complex geometries than 2-axis or 3-axis CNC machines.
Below is a summary of the movement of the axes:
X-axis: Left to right
Y-axis: Front to back
Z-axis: Top to bottom
A-axis: Rotation around the X-axis (tilts forward and backward)
B-axis: Rotation around the Y-axis (tilts from left to right)
