Four-axis CNC machining is an advanced manufacturing technology that adds a rotary axis to three-axis CNC machining. Compared with traditional three-axis CNC machining, four-axis CNC machining is more complex for the processing operation of the workpiece, which greatly improves processing efficiency and accuracy.
What is the working principle of four-axis CNC machining?
In a three-axis CNC machining centre, the tool moves along the X, Y, and Z axes, enabling the machining centre to perform both plane and solid machining. However, in the face of certain complex shapes, three-axis CNC machining may be limited. Four-axis CNC machining adds an axis of rotation (usually axis A or B) to this purpose, which rotates the tool or workpiece around a specific axis, allowing for more diverse machining operations.
By adding this axis of rotation, what operations can be performed on a four-axis CNC machining centre?
●Multi-functional machining: The workpiece can be rotated to different angles to avoid multiple processing and improve processing efficiency.
●Spiral machining: machining complex curves such as threads and spiral grooves.
●Bevel machining: machining of the surface of a part with an inclined plane or angle.
What are the advantages of four-axis CNC machining?
●Increased machining efficiency: Since the workpiece can be machined at different angles, multiple faces can be completed in one clamping, reducing the time for multiple chucks and workpiece alignment.
●Improve machining accuracy: reduce the error caused by multiple oil smoke in four-axis machining, and ensure the consistency of machining accuracy.
●Extended machining range: Four-axis CNC machining can handle complex geometries and surfaces that cannot be achieved with three-axis CNC machining centres, greatly expanding the range of parts that can be machined.
●Simplify the machining process: The use of rotating axes can simplify the machining process steps of some complex parts and reduce production difficulties.
