Multi-Axis CNC Machining: Precision Components in 3, 4, and 5 Axes
What Is Multi-Axis Machining?
Multi-axis CNC machining is an advanced manufacturing process that allows simultaneous movement of cutting tools along multiple axes—3-axis, 4-axis, and 5-axis—to produce complex, high-precision parts with tight tolerances. By enabling rotational and angular movements in addition to linear X, Y, and Z axes, multi-axis machining can create intricate geometries, undercuts, angled surfaces, and contoured profiles that are difficult or impossible with standard CNC methods.
This process is widely used for aerospace components, automotive parts, medical devices, molds, dies, and precision engineering parts, delivering both efficiency and accuracy in prototyping and production.
主要特征和优势
3-Axis Machining – Moves along X, Y, and Z axes; ideal for simple prismatic parts and flat surfaces. Accuracy up to ±0.01 mm.
4-Axis Machining – Adds rotational motion around the X-axis (A-axis), allowing features like slots, pockets, and angled cuts. Suitable for small batch production with cycle times 20–30% faster than sequential setups.
5-Axis Machining – Provides simultaneous movement along X, Y, Z axes plus A and B rotational axes. Enables complex surfaces, free-form contours, multi-sided machining in a single setup. Tolerance as tight as ±0.005 mm, surface finish Ra 0.4 μm achievable.
Complex Geometry Capability – Undercuts, curved surfaces, deep pockets, and compound angles can be machined efficiently.
Material Flexibility – Metals (aluminum, stainless steel, titanium, brass, copper alloys) and high-performance plastics (PEEK, PTFE, POM, ABS).
