5-axis machining centres are becoming increasingly popular due to their ability to machine complex parts with high precision. However, there are many different combinations of 5-axis machines, and it can be difficult to know which one is the best to use for your application. This blog discusses the three most common 5-axis kinematics: trunnion table, swivel head, and bi-axis head.
What are 5-axis kinematics?
5-axis kinematics is the study of the motion of a 5-axis machine tool. The five axes are typically three linear axes (X, Y, and Z) and two rotary axes (A and B). The rotary axes can be configured in a number of different ways, which is what gives rise to the different 5-axis kinematics.
Trunnion Table
The first combination is the table-table type which is commonly known as Trunnion Table. This type of machine is often found on smaller machines and is traditionally utilised to machine impellers, blades, and engine blocks. Trunnion table machines are a good choice for machining parts that require a lot of flexibility in tool orientation.
Swivel Head
The second type is the head-table or Swivel Head model, which can give a lot of flexibility from the rotary axis to handle workpieces, even if they are reasonably heavy. This method utilises the benefits of turning the piece to work as a lathe. Swivel head machines are a good choice for machining parts that are too large or heavy to be machined on a trunnion table machine.
Bi-Axis Head
The third type is the head-head or Bi-Axis Head type, which is best for handling much more substantial workpieces and when machining is required at different heights on a single workpiece. Bi-axis head machines are a good choice for machining very large or complex parts.
Choosing the Right 5-Axis Kinematics
The best way to choose the right 5-axis kinematics for your application is to consider the following factors:
- The complexity of the parts you are machining: If you are machining complex parts with a lot of undercuts, you will need 5-axis kinematics that can provide a lot of flexibility in tool orientation.
- The size of the parts you are machining: If you are machining large parts, you will need 5-axis kinematics that can provide a lot of travel.
- If you need to machine parts with high accuracy, you will need 5-axis kinematics that are very precise.
We hope this provides an overview of the most recognisable 5-axis kinematics of CNC machines. See the selection of 5-Axis machines from Hyundai-Wia & Hartford which are available exclusively in the United Kingdom and Irish Republic from Ward CNC here.
